I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.
Man is not only a contributory creature, but a total creature; he does not only make one, but he is all; he is not a piece of the world, but the world itself, and next to the glory of God, the reason why there is a world.
