Talent is able to achieve what is beyond other people's capacity to achieve, yet not what is beyond their capacity of apprehension; therefore it at once finds its appreciators. The achievement of genius, on the other hand, transcends not only others' capacity of achievement, but also their capacity of apprehension; therefore they do not become immediately aware of it. Talent is like the marksman who hits a target which others cannot reach; genius is like the marksman who hits a target, as far as which others cannot even see.

Animals learn death first at the moment of death;...man approaches death with the knowledge it is closer every hour, and this creates a feeling of uncertainty over his life, even for him who forgets in the business of life that annihilation is awaiting him. It is for this reason chiefly that we have philosophy and religion.
