De què tracta
Per què uns éssers vius duren molt i altres poc.
Context i història
Una de les primeres temptatives de trobar una llei general de la durada de la vida, relacionant-la amb la humitat, la mida i el medi. Interessa com a plantejament del problema: la pregunta de per què les espècies envelleixen a ritmes tan diferents encara és de biologia viva. Forma part dels «Parva naturalia», els vuit opuscles breus que continuen la «De anima» aplicant-ne la teoria a fenòmens concrets del cos viu. Es transmeten com un grup i es llegeixen millor seguits.

But we must discover the reason why trees are of an enduring constitution, for it is peculiar to them and is not found in any animals except the insects. Plants continually renew themselves and hence last for a long time. New shoots continually come and the others grow old, and with the roots the same thing happens. But both processes do not occur together. Rather it happens that at one time the trunk and the branches alone die and new ones grow up beside them, and it is only when this has taken place that the fresh roots spring from the surviving part. Thus it continues, one part dying and the other growing, and hence also it lives a long time. There is a similarity, as has been already said, between plants and insects, for they live, though divided, and two or more may be derived from a single one. Insects, however, though managing to live, are not able to do so long, for they do not possess organs; nor can the principle resident in each of the separated parts create organs. In the case of a plant, however, it can do so; every part of a plant contains potentially both root and stem. Hence it is from this source that issues that continued growth when one part is renewed and the other grows old; it is practically a case of longevity. The taking of slips furnishes a similar instance, for we might say that, in a way, when we take a slip the same thing happens; the shoot cut off is part of the plant. Thus in taking slips this perpetuation of life occurs though their connexion with the plant is severed, but in the former case it is the continuity that is operative. The reason is that the life principle potentially belonging to them is present in every part.
