I am an anarchist, a political and social Huguenot; I deny everything and affirm naught but myself: because the sole truth of which I have material and moral proof and tangible, comprehensible and intelligible evidence, the only real, startling, non-arbitrary truth not susceptible to interpretation, is myself. I am. There I have a positive fact. Everything else is abstraction and, in mathematics, would be designated as "x", and unknown quantity; and I need not trouble myself with it.
