From: Leo Tolstoy, Anna Karenina, Penguin, 2006, p.239. Translated by Richard Pevear and Larissa Volokhonsky. (Original date of publication 1873-77.)

“Konstantin Levin regarded his brother as a man of great intelligence and education, noble in the highest sense of the word, and endowed with the ability to act for the common good. But, in the depths of his soul, the older he became and the more closely he got to know his brother, the more often it occurred to him that this ability to act for the common good, of which he felt himself completely deprived, was perhaps not a virtue but, on the contrary, a lack of something – not a lack of good, honest and noble desires and tastes, but a lack of life force, of what is known as heart, of that yearning which makes a man choose one out of all the countless paths in life presented to him and desire that one alone. The more he knew his brother, the more he noticed that Sergei Ivanovich and many other workers for the common good had not been brought to this love of the common good by the heart, but had reasoned in their minds that it was good to be concerned with it and were concerned with it only because of that. And Levin was confirmed in this surmise by observing that his brother took questions about the common good and the immortality of the soul no closer to heart than those about a game of chess or the clever construction of a new machine.”

Note: I don’t find this persuasive but find it interesting none the less
