No problem has a solution. None of us can untie the Gordian knot; all of us either give up or cut it. We use our feelings indiscriminately to resolve problems of our intelligence, and we do it because we are tired of thinking or because we are too timid to draw conclusions, out of an absurd [?] necessity to find a support, or out of a gregarious impulse to return to the others and to life.
Since we can never know all the elements in a problem, we can never solve it. We lack the data necessary to attain the truth as well as the intellectual processes that would exhaust the interpretation of those data.
— Bernardo Soares (Fernando Pessoa), The Book of Disquiet
