Dreams in the history of philosophy.

For 2,500 years western philosophers showed great interest in dreams—as subjects, examples, analogies, and contexts. Since 1960 this interest has declined, while scholars in other disciplines continue to study dreams, often addressing philosophical issues. The history and the current dialogue invite philosophers to reinvigorate their study of dreams. This essay develops these observations about the philosophy of dreams by focusing on its history, briefly noting its recent decline, and closing with comments about its future.
