“Penalties are only missed by those who have the courage to take them.”

Letter to Sophie Germain (30 April 1807) ([...]; les charmes enchanteurs de cette sublime science ne se décèlent dans toute leur beauté qu'à ceux qui ont le courage de l'approfondir. Mais lorsqu'une personne de ce sexe, qui, par nos meurs [sic] et par nos préjugés, doit rencontrer infiniment plus d'obstacles et de difficultés, que les hommes, à se familiariser avec ces recherches épineuses, sait néanmoins franchir ces entraves et pénétrer ce qu'elles ont de plus caché, il faut sans doute, qu'elle ait le plus noble courage, des talents tout à fait extraordinaires, le génie superieur.)
Context: The enchanting charms of this sublime science reveal themselves in all their beauty only to those who have the courage to go deeply into it. But when a person of that sex, that, because of our mores and our prejudices, has to encounter infinitely more obstacles and difficulties than men in familiarizing herself with these thorny research problems, nevertheless succeeds in surmounting these obstacles and penetrating their most obscure parts, she must without doubt have the noblest courage, quite extraordinary talents and superior genius.

Original: In questo mondo, per sopravvivere devi essere una donna forte, coraggiosa, una donna che supera le difficoltà trasformandole in successi. Una donna con dedizione, intuizione, costanza, onore, lealtà e dolcezza. Una donna non per tutti, ma solo per chi osa averla al suo fianco.

Day of Affirmation Address (1966)
Context: The second danger is that of expediency: of those who say that hopes and beliefs must bend before immediate necessities. Of course, if we must act effectively we must deal with the world as it is. We must get things done. But if there was one thing that President Kennedy stood for that touched the most profound feeling of young people around the world, it was the belief that idealism, high aspirations, and deep convictions are not incompatible with the most practical and efficient of programs — that there is no basic inconsistency between ideals and realistic possibilities, no separation between the deepest desires of heart and of mind and the rational application of human effort to human problems. It is not realistic or hardheaded to solve problems and take action unguided by ultimate moral aims and values, although we all know some who claim that it is so. In my judgment, it is thoughtless folly. For it ignores the realities of human faith and of passion and of belief — forces ultimately more powerful than all of the calculations of our economists or of our generals. Of course to adhere to standards, to idealism, to vision in the face of immediate dangers takes great courage and takes self-confidence. But we also know that only those who dare to fail greatly, can ever achieve greatly.
