Abstract
Being at the heart of all sciences, Philosophy is an understanding of thinking, knowing, enlightenment and practical life wisdom aimed at researching and enlightening the ways for human to be happy on earth, at the final point. In other words, it means to explore the ways and the methods to achieve eunoia, that is, "good thinking", "having a well-balanced mind" and finally "goodwill" and "kindness". For this reason, philosophy is the knowledge, wisdom and method of holistic thinking and action. Benefiting from the results of every science that studies all intellectual, emotional and behavioural accumulation of humanity individually within their borders, by their own methods, stems from the nature of this holistic approach of philosophy.
