Abstract: Philosophy is the study of general and fundamental problems, connected with human existence, knowledge, values, reason, mind, morality, science and language. Philosophy is the critical examination of the grounds for fundamental beliefs and an analysis of the basic concepts employed in the expression of such beliefs. Philosophical problems characterize human life and human history: philosophical inquiry is a central element in the intellectual history of many historical civilizations. Philosophical theories are answers related to our philosophical problems. In this horizon, it is very important to analyze the semantic connection between “history of philosophy” and “philosophy of science”, which is a branch of philosophy concerned with the foundations, methods and implications of science and “scientific theories”.
