Sadism is motivated by the wish to know the secret, yet I remain as ignorant as I was before.  I have torn the other being apart limb from limb, yet all I have done is to destroy him.  Love is the only way of knowledge, which in the act of union answers my quest.  In the act of loving, of giving myself, in the act of penetrating the other person, I find myself, I discover myself, I discover us both, I discover man.'
