Sensual pleasure passes and vanishes, but the friendship between us, the mutual confidence, the delight of the heart, the enchantment of the soul, these things do not perish and can never be destroyed.

This astonishes our dimension of brains, which is only about six inches long, five broad, and six in depth, in the largest heads.
