Professor John Gardner says on the jacket, “these essays – without exception insightful and penetrating – set a high standard for the rest of us to aspire to.” This collection of 15 essays by 16 Canadian authors originated in a conference at Osgoode Hall Law School, York University. The majority of contributors are based in southern Ontario (Osgoode or York 5, Western 3, Toronto 2, and Queen’s 1). Two are from western Canada (Alberta, Saskatchewan), two from the UK (Manchester, Oxford) and one from the US (Cornell). The essays are arranged in three parts, the first being subdivided according to subject matter. It is a good thing for criminal law theorists to interest themselves in all facets of the subject. On the other hand, some will be deterred by the presence of essays on topics outside their specialty. It must be said that it is a well-produced book, even containing a subject index. I hope this book has wide circulation.
