WORDS AND RULES.
Stephen Pinker, professor of psychology from the Massachusetts Institute of Technology, is giving the 1999 Lucent-Colin Memorial Lecture at Imperial College, London SW7, 5.30pm. His theme is that human language is made possible by "the arbitrary sound-meaning pairing underlying words, and the discrete combinatorial system underlying grammar".
