Professor Richard Epstein delivered the keynote address titled "A common lawyer looks at the constitutional protection for freedom of speech" during the 2017 National Student Symposium at Columbia Law School on Saturday, March 4, 2017. -- The theme of this talk is what happens if we think about freedom of speech as an ideal, without any of the standard constitutional glosses—strict scrutiny, purposive interpretations—and then how does it play out. It does differ from the current law, quite radically on some key question that lie at the border line between tortious actions and free speech: offensive behavior, intentional infliction of emotional distress, defamation, deceit, coercion and the like. The answers sometimes overlap and sometimes differ, and I hope to explain why the common law approach is superior. -- Keynote: Prof. Richard Epstein, Laurence A. Tisch Professor of Law, New York University School of Law. Introduction: Mr. Shiva H. Logarajah, Symposium Chair, Columbia Law School Student Chapter.
