The abstract intelligence produces a fatigue that's the worst of all fatigues. It doesn't weigh on us like bodily fatigue, nor disconcert like the fatigue of emotional experience. It's the weight of our consciousness of the world, a shortness of breath in our soul.
Fernando PessoaThere'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 PessoaNever having discovered qualities in myself which could attract someone else, I could never believe that anyone felt attracted to me.
Fernando Pessoa
