Philosophical Investigations

Ludwig Wittgenstein
c. 1929–49 (drafted across two decades); 1953 (posthumous publication, ed. Anscombe & Rhees) · German (with parallel English by G. E. M. Anscombe)
Numbered remarks (§1–§693) plus Part II / "Philosophy of Psychology — A Fragment" · Analytic philosophy / ordinary-language philosophy

Meaning is use — language is a family of games — philosophy leaves everything as it is, and the picture of the inner that held us captive is dismantled

Dimension-by-Dimension Evidence

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

Time

Philosophical Investigations

The Investigations do not theorise time as such, but the whole approach is recognisably anti-Tractarian: meanings are constituted in the temporal extension of practices, not in atemporal logical relations. Time is real and relational in the strong Wittgensteinian sense — there is no fact about meaning prior to the time-extended practice of meaning-use.

Space

Philosophical Investigations

Not directly engaged. The implicit framework is the space of human practices and forms of life — relational, lived, oriented.

Matter

Philosophical Investigations

Not theorised. The Tractatus's "objects" are gone; the Investigations leave matter to the empirical sciences and to the ordinary practices in which we use object-language. Matter is real but relational in the precise sense that object-talk derives its content from use.

Observer

Philosophical Investigations

The Investigations' observer is plural, embodied, enmeshed in language-games, and self-corrected through reflective attention to the use of words. There is no transcendental subject (a major departure from the Tractatus). Knowledge is immediate but always practice-embedded. The "private language argument" (§§243–315) is the textual heart of the analysis of mind: there is no logically private inner realm; sensations have public criteria.

Energy

Philosophical Investigations

Not engaged. The framework is consistent with standard physical energetics in ordinary use.

Information

Philosophical Investigations

No substantival informational structure prior to use; no preserved inner record. Personal information is not philosophically privileged — the Investigations's analysis of pain, memory, and inner experience systematically displaces the picture of the inner as a private container of preserved data.

Internal Tensions

Where each work's argument pulls against itself.

Philosophical Investigations

The relation between the Tractatus and the Investigations is the most-discussed author-stage problem in twentieth-century philosophy. Wittgenstein insisted that the two be read together — he wanted the Tractatus printed alongside the Investigations — but the philosophical positions are genuinely different. Resolute readers of the Tractatus try to soften the apparent break by reading the earlier work as already therapeutic; standard readers accept the change as a major philosophical reversal. The compare-pair on this site exists in part to make this disagreement legible.
