Sergey Ivanovitch merely shrugged his shoulders, as though to express his wonder how the birch branches had come into their argument at that point, though he did really understand at once what his brother meant.
“Excuse me, but you know one really can’t argue in that way,” he observed.
But Konstantin Levin wanted to justify himself for the failing, of which he was conscious, of lack of zeal for the public welfare, and he went on.
“I imagine,” he said, “that no sort of activity is likely to be lasting if it is not founded on self-interest, that’s a universal principle, a philosophical principle,” he said, repeating the word “philosophical” with determination, as though wishing to show that he had as much right as anyone else to talk of philosophy.
Sergey Ivanovitch smiled. “He too has a philosophy of his own at the service of his natural tendencies,” he thought.
“Come, you’d better let philosophy alone,” he said. “The chief problem of the philosophy of all ages consists just in finding the indispensable connection which exists between individual and social interests. But that’s not to the point; what is to the point is a correction I must make in your comparison. The birches are not simply stuck in, but some are sown and some are planted, and one must deal carefully with them. It’s only those peoples that have an intuitive sense of what’s of importance and significance in their institutions, and know how to value them, that have a future before them—it’s only those peoples that one can truly call historical.”
And Sergey Ivanovitch carried the subject into the regions of philosophical history where Konstantin Levin could not follow him, and showed him all the incorrectness of his view.
