No discipline can be entirely independent, however, to some degree, it must or else we would otherwise confuse all the different studies together. The separation in different studies kind of organize our areas of focus and helps keep us from thinking too abroad. For example, one can argue that language and imagination ( an anthropological suggestion ) is formerly the first sign of mathematical intelligence instead of regarding ( as nearly every mathematician would insist ) simple arithmetic operations as being the first. Both are correct because language and imagination inevitably lead to mathematical intelligence, yet the question is carried to a very obscure place where ( if we are going to think that abroad ) there would be far too many factors and possibilities to consider that we would eventually change course from the main focus.
My question is, the study of psychology and philosophy are separate fields that focus on different things but can they intermix to bring more clarity without the results being too broad and obscure?
