"This is one of the best introductions to philosophy I know of. It covers many subdisciplines of theoretical philosophy, is extremely well-argued, and is wittily written. It teaches precision in both concept-formation and argumentation but does not invest it in all-too abstract and irrelevant problems. Instead, it focuses on the great issues of philosophy—from the existence of God to the nature of the mind. Even the expert philosopher will benefit from it."

Vittorio G. Hösle, University of Notre Dame, USA

"Virtually without exception, present-day introductions to philosophy are anthologies, mosaics of thought combining deliberations from varied sources and points of view. The systemic unity of thought that ought to be the hallmark of rigorous philosophy is entirely absent from such a Cook's tour transit across the landscape of thought. The unique feature of Tennant’s book is that it traverses a vast array of key issues from an integrated and consistent conceptual and methodological point of view. It superimposes upon thematic and doctrinal diversity a deeply insightful and analytical unity. The book will be a delight to teach."
