The speech is part of a process of mending fences between the justice and the school where he obtained his law degree in 1974, The Washington Post reported. Thomas visited Yale in December, addressing the conservative Federalist Society and the Black Law Students Association and jointly teaching a class with a law professor -- a liberal one.
In his autobiography, "My Grandfather's Son," Thomas said he felt his Yale degree had no value when he graduated because of affirmative action. In fact, he said, he stuck a 15-cent sticker from a box of cigars on the degree and stored it in the basement.
"I'd learned the hard way that a law degree from Yale meant one thing for white graduates and another for blacks, no matter how much anyone denied it," he wrote.
His confirmation battle did nothing to change his mind, when Anita Hill, a member of the class of 1980 at Yale, accused him of sexual harassment.
