Human knowledge and skills alone cannot lead humanity to a happy and dignified life. Humanity has every reason to place the proclaimers of high moral standards and values above the discoverers of objective truth.
There are some who esteem that it is a naivety to believe that a moral regeneration may be possible ("soit possible", Fr.); now, if this was not the case, it would not be worth the trouble that humanity continue to vegetate without aim.
Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.
Our chief usefulness to humanity rests on our combining power with high purpose. Power undirected by high purpose spells calamity, and high purpose by itself is utterly useless if the power to put it into effect is lacking.
