This book investigates whether adopting a non-Fregean intensionalist framework can resolve long-standing, intractable problems within the philosophy of language and related logical paradoxes. Jerrold J. Katz, a prominent philosopher of language, utilizes his expertise in semantic theory to challenge traditional Fregean assumptions. He argues that by shifting the foundational approach to sense and reference, one can achieve more coherent solutions to classic philosophical dilemmas. The text systematically applies this revised intensionalist methodology to demonstrate its explanatory power across various linguistic and logical puzzles.

Experts recognize this work as a significant contribution to the debate surrounding semantic theory and the limitations of Fregean logic. Readers frequently note the academic density of the prose, which requires a strong background in analytic philosophy to fully grasp the author's arguments.
