J. M. E. McTaggart

J. M. E. McTaggart. John McTaggart Ellis McTaggart was a prominent English metaphysician and a leading figure in the tradition of British idealism. Educated at Trinity College, Cambridge, he spent his entire academic career as a fellow and lecturer at his alma mater, profoundly influencing generations of students and philosophers. He is best known for his rigorous and paradoxical argument for the unreality of time, a thesis that has remained a central puzzle in the philosophy of time. His major works, including The Nature of Existence, systematically develop a unique idealist metaphysics grounded in a pluralistic universe of loving souls.

Life and career

Born in London, McTaggart entered Clifton College before winning a scholarship to Trinity College, Cambridge in 1885. At Cambridge University, he fell under the influence of the idealist philosopher Henry Sidgwick and immersed himself in the works of G. W. F. Hegel. He was elected a fellow of Trinity College, Cambridge in 1891, a position he held, alongside a university lectureship, for the rest of his life, becoming a central and somewhat eccentric figure in Cambridge philosophical circles. A committed atheist and a socialist, he was also a member of the Cambridge Apostles, a secret society that included figures like G. E. Moore and John Maynard Keynes. His personal life was marked by deep friendships, most notably with the philosopher Bertrand Russell in their early careers, though they later diverged philosophically.

Philosophy

McTaggart’s philosophical system is a distinctive blend of absolute idealism and rigorous logical analysis. While influenced by Hegel, he rejected Hegel's monism, arguing instead for a pluralistic universe composed ultimately of immaterial substances, which he termed souls. His magnum opus, the two-volume The Nature of Existence, employs a deductive method to argue that the only things that truly exist are souls standing in a direct relation of love, a conclusion he saw as necessitated by the fundamental categories of existence. This work engaged critically with other major philosophical traditions, including the logical atomism of Bertrand Russell and the new realism emerging in America. His style was characterized by exceptional clarity and a relentless pursuit of logical consequences, earning him great respect even from philosophical opponents.

The unreality of time

McTaggart’s most famous and enduring contribution is his argument for the unreality of time, first presented in a 1908 paper in the journal Mind and later expanded in The Nature of Existence. He distinguished between two ways of ordering events: the **A-series** (positions of past, present, and future) and the **B-series** (positions of earlier than and later than). He argued that time essentially involves change, and genuine change requires the A-series, as the B-series is static. He then famously contended that the A-series is inherently contradictory because every event has all A-properties (past, present, and future), which are mutually incompatible. This paradox, known as **McTaggart’s paradox**, led him to conclude that time is unreal. The debate between **A-theory** and **B-theory** of time, framing much contemporary philosophy of time, originates directly from this argument.

Influence and legacy

Despite the general decline of British idealism, McTaggart’s work on time has secured his lasting philosophical legacy. His paradox forced philosophers like C. D. Broad, who dedicated a substantial section of his Examination of McTaggart's Philosophy to it, and later A. J. Ayer and D. H. Mellor, to grapple with the metaphysics of temporality. The framework of the A-series and B-series became foundational, influencing major 20th-century thinkers including Michael Dummett and contemporary debates in the philosophy of physics. His rigorous method also impressed early analytic philosophers, and his arguments continue to be a mandatory reference point in university courses on metaphysics and the philosophy of time, ensuring his ideas remain actively discussed in journals like The Philosophical Review.

Published works

McTaggart’s philosophical output, though not voluminous, is highly systematic. His first major work was Studies in the Hegelian Dialectic (1896), followed by Studies in Hegelian Cosmology (1901). The seminal paper “The Unreality of Time” appeared in Mind in 1908. His definitive system is presented in the two-volume The Nature of Existence (Vol. I, 1921; Vol. II, edited posthumously by C. D. Broad in 1927). Broad also edited a collection of his shorter writings, Philosophical Studies, in 1934. These works collectively outline his unique idealist metaphysics and his timeless argument against the reality of time.
