Psychiatry has undergone a dynamic evolution since the 1950s, an evolution to which Dr. Louis West made many contributions. Psychiatry today and Dr. West's career are intertwined in a mosaic of interaction. It is therefore fitting that this compilation of essays in honour of Dr. West is entitled "The Mosaic of Contemporary Psychiatry: Current Perspectives". The papers collectively form a snapshot of the field of psychiatry today. Each chapter offers a historical perspective of the topic discussed, followed by a description of modern day issues and a look at the future of psychiatry.
