Context

“I perceive, I said, that you have or have had experiences of this sort, and I agree. But let me ask you another question: Has excess of pleasure any affinity to temperance? How can that be? he replied; pleasure deprives a man of the use of his faculties quite as much as pain. Or any affinity to virtue in general? None whatever. Any affinity to wantonness and intemperance? Yes, the greatest. And is there any greater or keener pleasure than that of sensual love? No, nor a madder.” source
