Fyodor Dostoyevsky said this quote
“ He was, however, unable to give much prolonged or continuous thought to anything that evening , or to concentrate on any one idea; and anyway, even if he had been able to, he would not have found his way to a solution of these questions in a conscious manner; now he could only feel. In place of dialectics life had arrived, and in his consciousness something of a wholly different nature must now work towards fruition. ”
