This collection of essays is based on papers read at a conference on freedom of expression, held at McMaster University, Ontario, Canada, in May, 1990. Its contributors are philosophers and lawyers who bring their own perspectives to bear on issues surrounding the justification of free expression and the bases, both legal and moral, for restricting or broadening its scope. The contributors discuss legal attempts in America and Canada to restrict hate literature, or more specific aspects of free expression, namely, the freedom to express oneself in the language of one's choice and freedom of commercial expression.
