Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

The Nature of Existence

1921 (Vol. I); 1927 (Vol. II, posthumous). McTaggart died in January 1925 at age 58; his unfinished work was completed and published by Broad.

Space

The Nature of Existence

Trinity College, Cambridge — McTaggart's institutional base from 1885 until his 1925 death.

Matter

The Nature of Existence

Two-volume systematic metaphysical treatise (~600 pages total). Form is rigorously systematic-deductive: numbered sections, propositions, derivations.

Observer

The Nature of Existence

Late McTaggart. The observer is the philosophical metaphysician working in the last sustained generation of the British idealist tradition (alongside Bradley, Bosanquet, and Royce).

Energy

The Nature of Existence

Late-systematic energies. The book is the culmination of forty years of British-idealist metaphysical work, executed with a rigor that no other British-idealist had attempted.

Information

The Nature of Existence

Two-volume magnum opus. The volume II Unreality-of-Time argument has been the single most-discussed McTaggart passage in twentieth-century analytic philosophy.

Internal Tensions

Where each work's argument pulls against itself.

The Nature of Existence

McTaggart's magnum opus — the most concentrated late-British-idealist metaphysical synthesis and the source of the canonical Unreality of Time argument. The A-theory/B-theory distinction (McTaggart's framework) shaped twentieth-century philosophy of time; the personal-idealist conclusions did not survive analytic philosophy's anti-idealist turn (Moore, Russell), but the time-argument has been continuously productive.
