and died on the spot through holding his breath.
The Athenians buried him in the Ceramicus and honoured him in the decrees already cited above, adding their testimony of his goodness. Here is the epitaph composed for him by Antipater of Sidon Anth. Plan. iii.
104.: Here lies great Zeno, dear to Citium, who scaled high Olympus, though he piled not Pelion on Ossa, nor toiled at the labours of Heracles, but this was the path he found out to the stars--the way of temperance alone.
Here too is another by Zenodotus the Stoic, a pupil of Diogenes Anth. Pal. vii. 117.: Thou madest self-sufficiency thy rule, Eschewing haughty wealth, O godlike Zeno, With aspect grave and hoary brow serene.
A manly doctrine thine: and by thy prudence With much toil thou didst found a great new school, Chaste parent of unfearing liberty.
And if thy native country was Phoenicia, What need to slight thee? came not Cadmus thence, Who gave to Greece her books and art of writing?
And Athenaeus the epigrammatist speaks of all the Stoics in common as follows Anth. Pal. ix.
496.: O ye who've learnt the doctrines of the Porch And have committed to your books divine The best of human learning, teaching men That the mind's virtue is the only good!
She only it is who keeps the lives of men And cities,--safer than high gates and walls.
But those who place their happiness in pleasure Are led by the least worthy of the Muses.
We have ourselves mentioned the manner of Zeno's death in the Pammetros (a collection of poems in various metres): The story goes that Zeno of Citium after enduring many hardships by reason of old age was set free, some say by ceasing to take food; others say that once when he had tripped he beat with his hand upon the earth and cried, "I come of my own accord; why then call me?" Anth. Pal. vii. 118.
For there are some who hold this to have been the manner of his death.
So much then concerning his death.
Demetrius the Magnesian, in his work on Men of the Same Name, says of him: his father, Mnaseas, being a merchant often went to Athens and brought away many books about Socrates for Zeno while still a boy.
Hence he had been well trained even before he left his native place.
And thus it came about that on his arrival at Athens he attached himself to Crates. And it seems, he adds, that, when the rest were at a loss how to express their views, Zeno framed a definition of the end. They say that he was in the habit of swearing by "capers" just as Socrates used to swear by "the dog." Some there are, and among them Cassius the Sceptic and his disciples, who accuse Zeno at length. Their first count is that in the beginning of his Republic he pronounced the ordinary education useless: the next is that he applies to all men who are not virtuous the opprobrious epithets of foemen, enemies, slaves, and aliens to one another, parents to children, brothers to brothers, friends to friends.
Again, in the Republic, making an invidious contrast, he declares the good alone to be true citizens or friends or kindred or free men; and accordingly in the view of the Stoics parents and children are enemies, not being wise. Again, it is objected, in the Republic he lays down community of wives, and at line 200 prohibits the building of temples, lawcourts and gymnasia in cities; while as regards a currency he writes that we should not think it need be introduced either for purposes of exchange or for travelling abroad. Further, he bids men and women wear the same dress and keep no part of the body entirely covered.
That the Republic is the work of Zeno is attested by Chrysippus in his De Republica. And he discussed amatory subjects in the beginning of that book of his which is entitled "The Art of Love." Moreover, he writes much the same in his Interludes. So much for the criticisms to be found not only in Cassius but in Isidorus of Pergamum, the rhetorician. Isidorus likewise affirms that the passages disapproved by the school were expunged from his works by Athenodorus the Stoic, who was in charge of the Pergamene library; and that afterwards, when Athenodorus was detected and compromised, they were replaced. So much concerning the passages in his writings which are regarded as spurious.
There have been eight persons of the name of Zeno. First the Eleatic, of whom more hereafter; the second our present subject; the third a Rhodian who wrote a local history in one volume; the fourth a historian who wrote about the expedition of Pyrrhus into Italy and Sicily, and besides that an epitome of the political history of Rome and Carthage; the fifth a pupil of Chrysippus, who left few writings but many disciples; the sixth a physician of the school of Herophilus, a competent practitioner, though a poor writer; the seventh a grammarian, who besides other writings has left behind him epigrams; the eighth a Sidonian by birth and an Epicurean philosopher, lucid both in thinking and in style.
Of the many disciples of Zeno the following are the most famous: Persaeus, son of Demetrius, of Citium, whom some call a pupil and others one of the household, one of those sent him by Antigonus to act as secretary; he had been tutor to Antigonus's son Halcyoneus. And Antigonus once, wishing to make trial of him, caused some false news to be brought to him that his estate had been ravaged by the enemy, and as his countenance fell, "Do you see," said he, "that wealth is not a matter of indifference?"
The following works are by Persaeus: Of Kingship.
The Spartan Constitution.
Of Marriage.
Of Impiety.
Thyestes.
Of Love.
Exhortations.
Interludes.
Four books of Anecdotes.
Memorabilia.
A Reply to Plato's Laws in seven books.
Ariston, the son of Miltiades and a native of Chios, who introduced the doctrine of things morally indifferent; Herillus of Carthage, who affirmed knowledge to be the end; Dionysius, who became a renegade to the doctrine of pleasure, for owing to the severity of his ophthalmia he had no longer the nerve to call pain a thing indifferent: his native place was Heraclea; Sphaerus of Bosporus; Cleanthes, son of Phanias, of Assos, his successor in the school: him Zeno used to compare to hard waxen tablets which are difficult to write upon, but retain the characters written upon them. Sphaerus also became the pupil of Cleanthes after Zeno's death, and we shall have occasion to mention him in the Life of Cleanthes.
And furthermore the following according to Hippobotus were pupils of Zeno: Philonides of Thebes; Callippus of Corinth; Posidonius of Alexandria; Athenodorus of Soli; and Zeno of Sidon. Perhaps an error for Zeno of Tarsus.
I have decided to give a general account of all the Stoic doctrines in the life of Zeno because he was the founder of the School. I have already given a list of his numerous writings, in which he has spoken as has no other of the Stoics. And his tenets in general are as follows. In accordance with my usual practice a summary statement must suffice. Laertius adheres to his plan of arranging doctrine under two heads: (1) a general or summary, (2) a particular, treatment; cf. inf. vii. 48 kefala iwdw=s kata\ me/ros. Here follows a valuable and full doxography, extending to § 160, collected from various sources; §§ 49-83 come from Diocles. The classification is roughly as follows: Philosophic doctrine, say the Stoics, falls into three parts: one physical, another ethical, and the third logical. Zeno of Citium was the first to make this division in his Exposition of Doctrine, and Chrysippus too did so in the first book of his Exposition of Doctrine and the first book of his Physics; and so too Apollodorus and Syllus in the first part of their Introductions to Stoic Doctrine, as also Eudromus in his Elementary Treatise on Ethics, Diogenes the Babylonian, and Posidonius.
These parts are called by Apollodorus "Heads of Commonplace"; by Chrysippus and Eudromus specific divisions; by others generic divisions.
Philosophy, they say, is like an animal, Logic corresponding to the bones and sinews, Ethics to the fleshy parts, Physics to the soul. Another simile they use is that of an egg: the shell is Logic, next comes the white, Ethics, and the yolk in the centre is Physics. Or, again, they liken Philosophy to a fertile field: Logic being the encircling fence, Ethics the crop, Physics the soil or the trees.
Or, again, to a city strongly walled and governed by reason.
No single part, some Stoics declare, is independent of any other part, but all blend together. Nor was it usual to teach them separately. Others, however, start their course with Logic, go on to Physics, and finish with Ethics; and among those who so do are Zeno in his treatise On Exposition, Chrysippus, Archedemus and Eudromus.
Diogenes of Ptolemaïs, it is true, begins with Ethics; but Apollodorus puts Ethics second, while Panaetius and Posidonius begin with Physics, as stated by Phanias, the pupil of Posidonius, in the first book of his Lectures of Posidonius. Cleanthes makes not three, but six parts, Dialectic, Rhetoric, Ethics, Politics, Physics, Theology. But others say that these are divisions not of philosophic exposition, but of philosophy itself: so, for instance, Zeno of Tarsus. Some divide the logical part of the system into the two sciences of rhetoric and dialectic; while some would add that which deals with definitions and another part concerning canons or criteria: some, however, dispense with the part about definitions.
Now the part which deals with canons or criteria they admit as a means for the discovery of truth, since in the course of it they explain the different kinds of perceptions that we have. And similarly the part about definitions is accepted as a means of recognizing truth, inasmuch as things are apprehended by means of general notions. Further, by rhetoric they understand the science of speaking well on matters set forth by plain narrative, and by dialectic that of correctly discussing subjects by question and answer; hence their alternative definition of it as the science of statements true, false, and neither true nor false.
Rhetoric itself, they say, has three divisions: deliberative, forensic, and panegyric.
Rhetoric according to them may be divided into invention of arguments, their expression in words, their arrangement, and delivery; and a rhetorical speech into introduction, narrative, replies to opponents, and peroration.
Dialectic (they hold) falls under two heads: subjects of discourse and language. And the subjects fall under the following headings: presentations The word fantas i/a (=appearance or appearing) is a technical term in Stoic logic for which no one English equivalent is as yet unanimously adopted. It denotes the immediate datum of consciousness or experience, whether presented to sense or in certain cases to the mind. Hence "presentation" is nearer than "perception" or "impression." It might be thought to correspond to Locke's "simple ideas," for which Hume substituted "impressions and ideas"; but this is hardly so; for fantas i/ai are "given" as it were from without, and then with them as materials the mind itself constructs general notions and concepts. and the various products to which they give rise, propositions enunciated and their constituent subjects and predicates, and similar terms whether direct or reversed, genera and species, arguments too, moods, syllogisms and fallacies whether due to the subject matter or to the language; these including both false and true and negative arguments, sorites and the like, whether defective, insoluble, or conclusive, and the fallacies known as the Veiled, or Horned, No man, and The Mowers.
The second main head mentioned above as belonging to Dialectic is that of language, wherein are included written language and the parts of speech, with a discussion of errors in syntax and in single words, poetical diction, verbal ambiguities, euphony and music, and according to some writers chapters on terms, divisions, and style.
The study of syllogisms they declare to be of the greatest service, as showing us what is capable of yielding demonstration; and this contributes much to the formation of correct judgements, and their arrangement and retention in memory give a scientific character to our conception of things.
An argument is in itself a whole containing premisses and conclusion, and an inference (or syllogism) is an inferential argument composed of these. Demonstration is an argument inferring by means of what is better apprehended something less clearly apprehended.
A presentation (or mental impression) is an imprint on the soul: the name having been appropriately borrowed from the imprint made by the seal upon the wax.
There are two species of presentation, the one apprehending a real object, the other not. The former, which they take to be the test of reality, is defined as that which proceeds from a real object, agrees with that object itself, and has been imprinted seal-fashion and stamped upon the mind: the latter, or non-apprehending, that which does not proceed from any real object, or, if it does, fails to agree with the reality itself, not being clear or distinct.
Dialectic, they said, is indispensable and is itself a virtue, embracing other particular virtues under it. Cf. Plut. Mor. 874 e, and inf. §§ 62, 83. Freedom from precipitancy is a knowledge when to give or withhold the mind's assent to impressions. By wariness they mean a strong presumption against what at the moment seems probable, so as not to be taken in by it.
Irrefutability is strength in argument so as not to be brought over by it to the opposite side. Earnestness (or absence of frivolity) is a habit of referring presentations to right reason. Knowledge itself they define either as unerring apprehension or as a habit or state which in reception of presentations cannot be shaken by argument. Without the study of dialectic, they say, the wise man cannot guard himself in argument so as never to fall; for it enables him to distinguish between truth and falsehood, and to discriminate what is merely plausible and what is ambiguously expressed, and without it he cannot methodically put questions and give answers.
Overhastiness in assertion affects the actual course of events, so that, unless we have our perceptions well trained, we are liable to fall into unseemly conduct and heedlessness; and in no other way will the wise man approve himself acute, nimblewitted, and generally skilful in argument; for it belongs to the same person to converse well and to argue well, to put questions to the purpose and to respond to the questions put; and all these qualifications are qualifications belonging to the skilled dialectician.
Such is, summarily stated, the substance of their logical teaching. And in order to give it also in detail, Cf. supra,§ 38 note. This distinction between the general and particular treatment is also frequent in Sextus Empiricus: e.g. Pyrrh. Hyp. i. 5 cite as much of it as comes within the scope of their introductory handbook. I will quote verbatim what Diocles the Magnesian says in his Synopsis of Philosophers. These are his words: "The Stoics agree to put in the forefront the doctrine of presentation and sensation, inasmuch as the standard by which the truth of things is tested is generically a presentation, and again the theory of assent and that of apprehension and thought, which precedes all the rest, cannot be stated apart from presentation. For presentation comes first; then thought, which is capable of expressing itself, puts into the form of a proposition that which the subject receives from a presentation."
There is a difference between the process and the outcome of presentation.
The latter is a semblance in the mind such as may occur in sleep, while the former is the act of imprinting something on the soul, that is a process of change, as is set forth by Chrysippus in the second book of his treatise Of the Soul (De anima). For, says he, we must not take "impression" in the literal sense of the stamp of a seal, because it is impossible to suppose that a number of such impressions should be in one and the same spot at one and the same time. The presentation meant is that which comes from a real object, agrees with that object, and has been stamped, imprinted and pressed seal-fashion on the soul, as would not be the case if it came from an unreal object.
According to them some presentations are data of sense and others are not: the former are the impressions conveyed through one or more sense-organs; while the latter, which are not data of sense, are those received through the mind itself, as is the case with incorporeal things and all the other presentations which are received by reason. Of sensuous impressions some are from real objects and are accompanied by yielding and assent on our part. But there are also presentations that are appearances and no more, purporting, as it were, to come from real objects.
Another division of presentations is into rational and irrational, the former being those of rational creatures, the latter those of the irrational. Those which are rational are processes of thought, while those which are irrational have no name. Again, some of our impressions are scientific, others unscientific: at all events a statue is viewed in a totally different way by the trained eye of a sculptor and by an ordinary man.
The Stoics apply the term sense or sensation ( ai)/sqhs is ) to three things: (1) the current passing from the principal part of the soul to the senses, (2) apprehension by means of the senses, (3) the apparatus of the sense-organs, in which some persons are deficient. Moreover, the activity of the sense-organs is itself also called sensation.
According to them it is by sense that we apprehend black and white, rough and smooth, whereas it is by reason that we apprehend the conclusions of demonstration, for instance the existence of gods and their providence. General notions, indeed, are gained in the following ways: some by direct contact, some by resemblance, some by analogy, some by transposition, some by composition, and some by contrariety.
By incidence or direct contact have come our notions of sensible things; by resemblance notions whose origin is something before us, as the notion of Socrates which we get from his bust; while under notions derived from analogy come those which we get (1) by way of enlargement, like that of Tityos or the Cyclops, or (2) by way of diminution, like that of the Pygmy.
And thus, too, the centre of the earth was originally conceived on the analogy of smaller spheres. Of notions obtained by transposition creatures with eyes on the chest would be an instance, while the centaur exemplifies those reached by composition, and death those due to contrariety. Furthermore, there are notions which imply a sort of transition to the realm of the imperceptible: such are those of space and of the meaning of terms. The notions of justice and goodness come by nature. Again, privation originates notions; for instance, that of the man without hands. Such are their tenets concerning presentation, sensation, and thought.
The standard of truth they declare to be the apprehending presentation, i.e. that which comes from a real object--according to Chrysippus in the twelfth book of his Physics and to Antipater and Apollodorus. Boëthus, on the other hand, admits a plurality of standards, namely intelligence, senseperception, appetency, and knowledge; while Chrysippus in the first book of his Exposition of Doctrine contradicts himself and declares that sensation and preconception are the only standards, preconception being a general notion which comes by the gift of nature (an innate conception of universals or general concepts). Again, certain others of the older Stoics make Right Reason the standard; so also does Posidonius in his treatise On the Standard.
In their theory of dialectic most of them see fit to take as their starting-point the topic of voice. Now voice is a percussion of the air or the proper object of the sense of hearing, as Diogenes the Babylonian says in his handbook On Voice. While the voice or cry of an animal is just a percussion of air brought about by natural impulse, man's voice is articulate and, as Diogenes puts it, an utterance of reason, having the quality of coming to maturity at the age of fourteen. Furthermore, voice according to the Stoics is something corporeal: I may cite for this Archedemus in his treatise On Voice, Diogenes, Antipater and Chrysippus in the second book of his Physics.
For whatever produces an effect is body; and voice, as it proceeds from those who utter it to those who hear it, does produce an effect. Reduced to writing, what was voice becomes a verbal expression, as "day"; so says Diogenes. A statement or proposition is speech that issues from the mind and signifies something, e.g. "It is day." Dialect ( dia/- lektos ) means a variety of speech which is stamped on one part of the Greek world as distinct from another, or on the Greeks as distinct from other races; or, again, it means a form peculiar to some particular region, that is to say, it has a certain linguistic quality; e.g. in Attic the word for "sea" is not qa/lass a but qa/latt a, and in Ionic "day" is not h(me/ra but h(me/rh.
Elements of language are the four-and-twenty letters. "Letter," however, has three meanings: (1) the particular sound or element of speech; (2) its written symbol or character; (3) its name, as Alpha is the name of the sound A.
Seven of the letters are difference between voice and speech; because, while voice may include mere noise, speech is always articulate. Speech again differs from a sentence or statement, because the latter always signifies something, whereas a spoken word, as for example bli/tur i, may be unintelligible-- which a sentence never is. And to frame a sentence is more than mere utterance, for while vocal sounds are uttered, things are meant, that is, are matters of discourse.
There are, as stated by Diogenes i.e. the Babylonian.
in his treatise on Language and by Chrysippus, five parts of speech: proper name, common noun, verb, conjunction, article. To these Antipater in his work On Words and their Meaning adds another part, the "mean." Probably "adverb."
A common noun or appellative is defined by Diogenes as part of a sentence signifying a common quality, e.g. man, horse; whereas a name is a part of speech expressing a quality peculiar to an individual, e.g. Diogenes, Socrates. A verb is, according to Diogenes, a part of speech signifying an isolated predicate, or, as others Sc. Apollodorus and his school; cf. inf. § 64. define it, an un-declined part of a sentence, signifying something that can be attached to one or more subjects, e.g. "I write," "I speak." A conjunction is an indeclinable part of speech, binding the various parts of a statement together; and an article is a declinable part of speech, distinguishing the genders and numbers of nouns, e.g. o(, h(, to/, oi(, ai(, ta/. = "the," masc., fem. and neut., singular and plural.
There are five excellences of speech--pure Greek, lucidity, conciseness, appropriateness, distinction. By good Greek is meant language faultless in point of grammar and free from careless vulgarity.
Lucidity is a style which presents the thought in a way easily understood; conciseness a style that employs no more words than are necessary for setting forth the subject in hand; appropriateness lies in a style akin to the subject; distinction in the avoidance of colloquialism. Among vices of style barbarism is violation of the usage of Greeks of good standing; while there is solecism when the sentence has an incongruous construction.
Posidonius in his treatise On Style defines a poetical phrase as one that is metrical or rhythmical, thus mechanically avoiding the character of prose; an example of such rhythmical phrase is: O mightiest earth, O sky, God's canopy. Nauck, T.G.F. 2, Eur. 839.
And if such poetical phraseology is significant and includes a portrayal or representation of things human and divine, it is poetry.
A term is, as stated by Antipater in his first book On Terms, a word which, when a sentence is analysed, is uttered with complete meaning; or, according to Chrysippus in his book On Definitions, is a rendering back one's own. The author seems to have confused "term," which Antipater defines, with "definition," which, as Chrysippus says, is simply "giving back" the meaning in other words. Zeller's correction Dionysius Thrax. Delineation is a statement which brings one to a knowledge of the subject in outline, or it may be called a definition which embodies the force of the definition proper in a simpler form. Genus (in logic) is the comprehension in one of a number of inseparable objects of thought: e.g.
Animal; for this includes all particular animals.
A notion or object of thought is a presentation to the intellect, which though not really substance nor attribute is W. Thus an image of a horse may rise before the mind, although there is no horse present.
Species is that which is comprehended under genus: thus Man is included under Animal. The highest or most universal genus is that which, being itself a genus, has no genus above: namely, reality or the real; and the lowest and most particular species is that which, being itself a species, has no species below it, e.g. Socrates.
Division of a genus means dissection of it into its proximate species, thus: Animals are either rational or irrational (dichotomy). Contrary division dissects the genus into species by contrary qualities: for example, by means of negation, as when all things that are are divided into good and not good. Subdivision is division applied to a previous division: for instance, after saying, "Of things that are some are good, some are not good," we proceed, "and of the not good some are bad, some are neither good nor bad (morally indifferent)."
Partition in logic is (according to Crinis) classification or distribution of a genus under heads: for instance, Of goods some are mental, others bodily.
Verbal ambiguity arises when a word properly, rightfully, and in accordance with fixed usage denotes two or more different things, so that at one and the same time we may take it in several distinct senses: e.g. in Greek, where by the same verbal expression may be meant in the one case that "A house has three times" fallen, in the other that "a dancing-girl" has fallen.
Posidonius defines Dialectic as the science dealing with truth, falsehood, and that which is neither true nor false; whereas Chrysippus takes its subject to be signs and things signified. Such then is the gist of what the Stoics say in their theory of language.
To the department dealing with things as such and things signified is assigned the doctrine of expressions, including those which are complete in themselves, as well as judgements and syllogisms and that of defective expressions comprising predicates both direct and reversed. "Direct Predicate" answers to our Active Verb, "Predicate reversed" to our Passive; cf.
supra, 43.
By verbal expression they mean that of which the content corresponds to some rational presentation. Of such expressions the Stoics say that some are complete in themselves and others defective. Those are defective the enunciation of which is unfinished, as e.g. "writes," for we inquire "Who?" Whereas in those that are complete in themselves the enunciation is finished, as "Socrates writes." And so under the head of defective expressions are ranged all predicates, while under those complete in themselves fall judgements, syllogisms, questions, and inquiries.
A predicate is, according to the followers of Apollodorus, what is said of something; in other words, a thing associated with one or more subjects; or, again, it may be defined as a defective expression which has to be joined on to a nominative case in order to yield a judgement. Of predicates some are adjectival [and so have personal subjects], as e.g. "to sail through rocks." We should expect ta\ de\ parasum ba/mata to follow ( cf. Luc. Vit.
Auct. 21). By parasu/m bama is meant an impersonal verb with subject in oblique case, as me/lei moi. For other conjectures see Zeller, Phil. der Gr. iii. 1 3, 89 note 2, 90. Again, some predicates are direct, some reversed, some neither. Now direct predicates are those that are constructed with one of the oblique cases, as "hears," "sees," "converses"; while reversed are those constructed with the passive voice, as "I am heard," "I am seen." Neutral are such as correspond to neither of these, as "thinks," "walks." Reflexive predicates are those among the passive, which, although in form passive, are yet active operations, An attempt to distinguish what we call the Middle Voice from the Passive--as e.g. sune/qe nto, "they made compacts with each other," is more active ( o)rqa/ ) than passive ( u)/ptia ). as "he gets his hair from a fleece being shorn--"is both active and passive, as he suits his motions to the shaving.": for here the agent includes himself in the sphere of his action. The oblique cases are genitive, dative, and accusative.
A judgement is that which is either true or false, or a thing complete in itself, capable of being denied in and by itself, as Chrysippus says in his Dialectical Definitions: "A judgement is that which in and by itself can be denied or affirmed, e.g. `It is day,' `Dion is walking.'" The Greek word for judgement ( a)ci/wma ) is derived from the verb a)ciou=n, as signifying acceptance or rejection; for when you say "It is day," you seem to accept the fact that it is day. Now, if it really is day, the judgement before us is true, but if not, it is false.
There is a difference between judgement, interrogation, and inquiry, as also between imperative, adjurative, optative, hypothetical, vocative, whether that to which these terms are applied be a thing or a judgement. For a judgement is that which, when we set it forth in speech, becomes an assertion, and is either false or true: an interrogation is a thing complete in itself like a judgement but demanding an answer, e.g. "Is it day?" and this is so far neither true nor false. Thus "It is day" is a judgement; "Is it day?" an interrogation. An inquiry is something to which we cannot reply by signs, as you can nod Yes to an interrogation; but you must express the answer in words, "He lives in this or that place."
An imperative is something which conveys a command: e.g.
Go thou to the waters of Inachus. Nauck, T.G.F. 2, Adesp. 177; cf. Galen, xiii. p. 363 K.
An adjurative utterance is something...A vocative utterance is something the use of which implies that you are addressing some one ; for instance: Most glorious son of Atreus, Agamemnon, lord of men. Iliad ix. 96.
A quasi-proposition is that which, having the enunciation of a judgement, yet in consequence of the intensified tone or emotion of one of its parts falls outside the class of judgements proper, e.g.
Yea, fair indeed the Parthenon!
How like to Priam's sons the cowherd is! Nauck, T.G.F. 2, Adesp. 286.
There is also, differing from a proposition or judgement, what may be called a timid suggestion, the expression of which leaves one at a loss, e.g.
Can it be that pain and life are in some sort akin?
Interrogations, inquiries and the like are neither true nor false, whereas judgements (or propositions) are always either true or false.
The followers of Chrysippus, Archedemus, Athenodorus, Antipater and Crinis divide propositions into simple and not simple. Simple are those that consist of one or more propositions which are not ambiguous, as "It is day." Not simple are those that consist of one or more ambiguous propositions.
They may, that is, consist either of a single ambiguous proposition, e.g. "If it is day, it is day," or of more than one proposition, e.g.
"If it is day, it is light."
With simple propositions are classed those of negation, denial, privation, affirmation, the definitive and the indefinitive; with those that are not simple the hypothetical, the inferential, the coupled or complex, the disjunctive, the causal, and that which indicates more or less. An example of a negative proposition is "It is not day." Of the negative proposition one species is the double negative. By double negative is meant the negation of a negation, e.g. "It is not not-day." Now this presupposes that it is day.
A denial contains a negative part or particle and a predication: such as this, "No one is walking." A privative proposition is one that contains a privative particle reversing the effect of a judgement, as, for example, "This man is unkind." An affirmative or assertory proposition is one that consists of a noun in the nominative case and a predicate, as "Dion is walking." A definitive proposition is one that consists of a demonstrative in the nominative case and a predicate, as "This man is walking." An indefinitive proposition is one that consists of an indefinite word or words and a predicate, e.g. "Some one is walking," or "There's some one walking"; "He is in motion."
Of propositions that are not simple the hypothetical, according to Chrysippus in his Dialectics and Diogenes in his Art of Dialectic, is one that is formed by means of the conditional conjunction "If." Now this conjunction promises that the second of two things follows consequentially upon the first, as, for instance,
