Man is not given that godlike unselfishness that thinks only of others' good.

Context

“The men wrong who, with bent back and sweating brow, cut the smooth road over which humanity marches forward from generation to generation! Men wrong for using the talents that their Master has intrusted to them—for toiling while others play! Of course they are seeking their reward. Man is not given that godlike unselfishness that thinks only of others' good. But in working for themselves they are working for us all. We are so bound together that no man can labor for himself alone. Each blow he strikes in his own behalf helps to mold the universe. The stream in struggling onward turns the mill-wheel;” source
