If there is one thing I have learned from reading the history of philosophy it is this: Time is freedom. An idea that has been forgotten, and has been replaced by a utopia of timelessness: retirement. It is obvious to me, that philosophy has one assignment: To free time from being a burden and combine it with our idea of freedom and possibility. This is a feat that only can be done through historical research.
Why? Because we need to learn to think in time.
