L'analogia physis-techne in Aristotele (Fisica B, 3-9) e la teoria interventistica della causalità

I have split the interpretation of chapters 3-9 of Aristotle's Physics B in tw parts: in chapters 3-7 the definition of the four causes is formulated and it is set the proble whether chance and fortune are causes of becoming, in chapters 8-9 this problem is solve in teleological way and the conclusions on the relation are drawn. The interventionis theory of causality claims that there is a strong connection between causality and huma intervention in nature: The idea of a causal relation between two events (one whic causes and the other which is caused) has as its presupposition the concept of intentiona action and it is generated by the reflection of man on his own operating with aims in the reality Though it is an archaic aspect, and against the contemporary positions of science, i Physics B Aristotle conceives the natural becoming as an operating which develops toward a precise aim; moreover the causa efficiens is in nature the active element whic gives raise to the movement and imposes the form, in analogy with the active element that i is the craftsman who operates the production. This analogy suggests that Aristotl conceives the efficient cause on the basis of the human ability to modify the environment, i agreement with the contemporary interventionist theory of causality.
