To create a doctrine, experience is not needed. Really, on the contrary, the less you know the better because then you can propose a system unhesitatingly. Only a blind man can easily define what light is. When you do not know you are bold. Ignorance is always bold; knowledge hesitates. And the more you know, the more you feel that the ground underneath is dissolving. The more you know, the more you feel how ignorant you are.
