In section 15 of The Crisis, Husserl offers an introspective investigation into ourselves guided by the teleology of philosophy. To try to understand ourselves, we must go back and examine what other philosophers of history have said to try to "understand the unity that runs through all the [philosophical] projects of history that 'oppose each other and work together in their shape-shifting'. To the extent that this historical analysis is personal, we are only part of the whole history of philosophy and have a role to play in building on what has been established before. In order to understand the teleological journey of philosophy and how we are part of it, we cannot simply look at it from the outside. We must try to understand it from within - we already have the spiritual-historical connection - if we truly want to know who we are. Husserl emphasizes that criticizing a current body of knowledge, a scientific or pre-scientific “Weltaschauung” is not sufficient to provide us with the answers to this philosophical quest. We can only find the answers we seek “through a critical understanding of the total unity of history – our history.” There is a certain spiritual connection between philosophers throughout history, and a critical analysis of their philosophies throughout time will illuminate our path as we seek to truly understand ourselves. What Husserl asserts is that philosophy has evolved over time, each step revealing more than before, and that we are meant to continue on this path until the "perfect vision" is finally achieved. This task is imposed on us as philosophers today because we are, after all, functionaries of modern philosophical humanity; we are the heirs and co-carriers of the direction of the ...... middle of article ...... philosophers of today, we are part of a long historical path that began with the primitive Greek settlement and which is set to continue with future generations until the final settlement is achieved. The concept of reductionism also attempts to bring together different things, different parts, to form a whole, unified form. We can trace the origins of modern scientific trends back to the early Greek establishment. From the simplistic Socratic approach of “Who am I?” ", philosophical self-reflection builds on thoughts and concepts like those of Galileo and Socrates until reaching current thinking. Modern scientific trends have developed from philosophies of the past and are part of the philosophical path that a philosopher must travel when undergoing self-reflection. They are a presentation of the prejudices of modern times, which the philosopher must seek to understand and overcome.
