Lincoln had no such person that he could talk with. Often, as a result, he debated with himself, and he would draw up a kind of list of the pros and cons of an argument, and carefully figure them out, and he might test them in public.

But I have tried to go over it very carefully, not merely what the evidence is, but with psychoanalysts and psychologists, and I think we're just about all agreed that Lincoln and Speed did not have a homosexual relationship.
