If out of all mankind one finds a single friend, he has found something more precious than any treasure, since there is nothing in the world so valuable that it can be compared to a real friend. Andreas Capellanus
The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter, I should have advised him to continue the generation of the species by fashioning them out of clay. Martin Luther
There is a law that man should love his neighbor as himself. In a few hundred years it should be as natural to mankind as breathing or the upright gait; but if he does not learn it he must perish. Alfred Adler
Leibniz dedicated his life to efforts to educate people to understand that true happiness is found by locating their identity in benefitting mankind and their posterity. Robert Trout
A person who has sympathy for mankind in the lump, faith in its future progress, and desire to serve the great cause of this progress, should be called not a humanist, but a humanitarian, and his creed may be designated as humanitarianism.
Irving Babbitt
