There's a tiredness of abstract inteligence, and it's the most horrible of tirednesses. It doesn't weight on you like the tiredness of the body, nor does it worry you like the tiredness of knowledge and emotion. It's a weightiness of the conscience of the world, an inability of the soul to breathe.
Fernando PessoaThere's something vile (and all the more vile because ridiculous) in the tendency of feeble men to make universal tragedies out of the sad comedies of their private woes.
Fernando PessoaGiving importance to what we think because we thought it, taking our own selves not only (to quote the Greek philosopher) as the measure of all things but as their norm or standard, we create in ourselves, if not an interpretation, at least a criticism of the universe, which we don't even know and therefore cannot criticize. The giddiest, most weak-minded of us then promote that criticism to an interpretation that's superimposed, like a hallucination; induced rather than deduced. It's a hallucination in the strict sense, being an illusion based on something only dimly seen.
