Drei Sichtweisen des Aristoteles auf die Natur1

This article tries to disentangle different perspectives on nature in Aristotle's biological work. In one sense Aristotle speaks of nature as a craft-like factor in the generation of living beings. In another sense 'nature' refers to Aristotle's conception of an unchanging universe, in which the individual living beings are perishable, but reproduce themselves and thus guarantee that the essential blueprints of the different species remain the same. In addition, however, Aristotle's zoology acknowledges natural processes that involve greater dynamics and more exceptions, most notably when it comes to the allocation of available matter within the animals of a certain species or to the adaptation to a species' proper environment. In conclusion, it seems fair to say that in Aristotle's zoology different autonomous perspectives overlap, so that it would be inappropriate to reduce all of them to a common denominator.
