Do you know why the philosophy emphasizes the soul-anima? What's the cause of the difference of opinion between biology and psychology on the one hand and philosophy on the other?
The clue exists in the meaning of philosophy: "A pursuit of wisdom. A search for a general understanding of values and reality by chiefly speculative rather than observational means. An analysis of the grounds of and concepts expressing fundamental beliefs."
If we add to this the meaning of to 'philosophize', we'll have a clearer picture: "To expound a moralizing and often superficial philosophy. To consider from or bring into conformity with a philosophic point of view."
So philosophy pursues wisdom, general understanding of values and reality. How does it do this? By speculative rather than observational means. If there is nothing to observe in the quantitative and/or qualitative sense, and if it has to analyse the grounds of and the concepts expressing fundamental beliefs it has to have a dimension which would link the material to the incorporeal, because it has to expound a moralizing and often superficial philosophy. That dimension is the soul or the spirit.
Philosophy has to find a way to explain this thing called the incorporeal and all the other subjects related to it. It is still trying. To no avail! That's the reason behind this difference of opinion.
