Psychology is about the way we know the object. Philosophy, instead, is about the object of knowledge. Psychology is about feelings and emotions. Such mental states are the way we grasp the object. But they are not the object of knowledge. Psychology tends to believe that reality is a psychic act, and does not make a distinction between thoughts, feelings, emotions and immutable essences, like laws of mathematics and logic, or structures of social reality.
Philosophy is, instead, about the weightless and invisible structures underlying reality. Quite often we inìdentify our thoughts with ourselves, or rather believe that reality, the object that appears is what we think and feel upon it. All this lead us to analyze our thoughts and emotions only, without freeing us from prejudices and grasping phenomena in the way they really appear. Philosophy is about “seeing” (idein).
