Throughout modern history, the philosophical imagination has created the philosophical perspectives of modern materialism, rationalism, empiricism, phenomenalism, historicism, existentialism, pragmatism, hermeneutics, and feminism. Although these schools of thought have their origin in the imagination, we all too often believe these perspectives give us access to truth itself, rather than being ways to make sense of our experience. Truth as something to know will always be relative to the imagination and the perspectives it creates. However, another notion of truth as something to be has emerged over the history of philosophical thought from Socrates to the present that is not relative to the changing perspectives of truth as something to know. This book distils the evolution of these concepts into an easily readable history of philosophy.
