Aggressivita' e istinto materno nella zoologia aristotelica: l'identita' sessuale tra maschile e femminile.

subject

description

As it appears in the Aristotelian Biological Corpus, male and female of the different species of animals differs in characters and, consequently, in their body constitutions. Since nature does nothing in vain, the former are courageus and made for a more active and violent life, and, for this reason, are endowed with natural weapons as horns, and stings. The latter are fearful and fragile, made for the care of offspring. There is a very close correspondence between body parts and attitudes and sexual behaviour: when the one changes, the others modify in the same way. There is just one period, during females life, in which their behaviour become naturally aggressive ad courageous in order to defend their offspring and to take care of it: the period after parturition.
