But who am I? What right have I to decide? What is it that determines my judgments? If they are inevitable… — Jean Jacques Rousseau

But who am I? What right have I to decide? What is it that determines my judgments? If they are inevitable, if they are the results of the impressions I receive, I am wasting my strength in such inquiries; they would be made or not without any interference of mine. I must therefore first turn my eyes upon myself to acquaint myself with the instrument I desire to use, and to discover how far it is reliable. I exist, and I have senses through which I receive impressions. This is the first truth that strikes me and I am forced to accept it.
