Yes, that is correct. Philosophy has never been a purely objective pursuit of truth, but rather it is an ongoing dialogue and investigation that is influenced by the cultural, social and historical context in which it is practiced. Philosophers are influenced by their own experiences, beliefs and biases, which inevitably shape their perspectives and understanding of the world.
Furthermore, the philosophical concepts and questions have often evolved in response to historical and cultural developments, and different cultures have developed distinct philosophical traditions. The ideas of Western philosophy, for example, are deeply rooted in the culture and history of ancient Greece, while Eastern philosophy has distinct concepts and traditions rooted in the culture and history of China, India, and Japan.
This doesn't mean that philosophy lacks objectivity or value, but it's important to recognize that philosophies are products of their time, place, and culture and that they are subject to change and revision over time. It is worth studying different philosophical perspectives to understand how the diverse cultures and societies have shaped their philosophies and the questions they were trying to answer, this provides a richer and more complete understanding of the subject.
