Nothing is more human than for man to desire naturally things impossible to his nature. It is, indeed, the property of a nature which is not closed up in matter like the nature of physical things, but which is intellectual or infinitized by the spirit. It is the property of a metaphysical nature. Such desires reach for the infinite, because the intellect thirsts for being and being is infinite.
