Peter Geach

Peter Geach was a British philosopher known for his work in meta-ethics, which examines the nature of moral statements and values. He challenged conventional views on ethics by introducing the idea that moral terms are often misunderstood when viewed through a purely logical lens. He also contributed to philosophical logic, particularly in the study of conditionals—statements that depend on hypothetical situations. Geach emphasized the importance of language in philosophy, arguing that analyzing how we use terms can clarify complex philosophical problems, helping us better understand both logical reasoning and moral discourse.
