Ideality of Meaning

Investigation I's central positive doctrine (husserl-1900-logical-investigations-vol1): the meaning (Bedeutung) of an expression is an ideal unity — "an identity in the strict sense, one and the same," whoever asserts it and however often — categorically distinct from the transient acts of meaning it unifies: "my act of judging is a transient experience: it arises and passes away. But what my assertion asserts… neither arises nor passes away" (§11). Its precise formulation (§31): the identity of meaning across acts is the identity of a species — meaning stands to acts of meaning "just as Redness in specie is to the slips of paper which lie here" — with metaphysical hypostatization expressly refused ("a τόπος οὐράνιος… would be absurd"). The doctrine culminates in the volume's most counterintuitive thesis (§35): meanings form "an ideally closed set of general objects, to which being thought or being expressed are alike contingent" — there are "countless meanings which… are never expressed, and… can never be expressed."

Key Points

Meaning ≠ act: the act is intimated, never asserted; "multiplication of persons and acts does not multiply propositional meanings; the judgement in the ideal, logical sense remains single" (§31). This holds even for false and absurd assertions.
Meaning ≠ object: reference runs through meaning — same object under different meanings ("the victor at Jena" / "the vanquished at Waterloo"), same meaning over different objects ("a horse" of Bucephalus and the cart-horse); "the object never coincides with the meaning" (§§12–13). Objectlessness is not meaninglessness: "golden mountain" and "round square" mean; what the absurd lacks is "the a priori impossibility of a fulfilling sense" (§15, with Marty's point that even to reject the round square one must mean it). Frege's Sinn/Bedeutung split is cited and declined — LI-era terminology is deliberately non-Fregean (§15 n.).
Specific, not normative, ideality (§32): the ideality of meaning is unity-in-multiplicity, "the complete opposite of reality or individuality" — not an ideal-of-perfection (which a real thing could realize). And meaning-as-species is not the object-species it presents: "the number 4 – the second even number in the number-series" is a generale whose object is the number 4 (§33).
Not normally an object: in the live act "we naturally refer to its object and not to its meaning"; meaning becomes objective "only in a reflex act of thought" — ideation (§34). Meaning is lived through, not inspected — which is why its ideality goes unnoticed by psychologism.
The occasional-expressions pressure (§26): "I," "here," "now" have meanings that necessarily vary with the occasion — "the word 'I' names a different person from case to case, and does so by way of an ever altering meaning" — analysed as an indicating meaning (the general function: "your vis-à-vis intends himself") supporting an indicated meaning (the singular presentation).
The promissory resolution (§28): fluctuation belongs to the act, not the meaning — "the content meant by the subjective expression… is an ideal unit of meaning in precisely the same sense as the content of a fixed expression" — secured by the ideal replaceability of every subjective by an objective expression, which "is no more than to assert the unbounded range of objective reason." Husserl concedes in the same breath that the replacement "will, in fact, never be" carried out: "we are infinitely removed from this ideal."
Husserl's own verdict: the 2nd-ed Foreword calls the occasional-meanings treatment "an act of violence – the enforced consequence of the imperfect conception of the essence of 'truth in itself' in the Prolegomena" — and notes that in strictness all empirical predication is occasional. The Sixth Investigation (Vol. II) is named as the correction site.

What the Concept Does

It is the hinge between the Prolegomena and the Investigations: the ideal propositions and truths pure-logic ranges over are meanings, so "all theoretical science consists, in its objective content, of one homogeneous stuff: it is an ideal fabric of meanings" (§29) — logic becomes the science of ideal meanings, and the psychologism refutation acquires its positive ontology. Within Investigation I it converts the intimated/asserted distinction into an ontological result; toward Investigation II it hands over the species-question ("the essence of universal objects" — deferred there explicitly). The mathematical exemplar carries the exhibition throughout (π, the perpendiculars-theorem, the number-series) — a monopoly the extraction note flags: ordinary occasional language resists the thesis "infinitely," on Husserl's own admission.

What It Rejects

The identification of meaning with the real act of judging (psychologism's semantic arm) and with accompanying images (imagism, §§17–18).
The identification of meaning with the object (which would make objectless names meaningless).
Platonic hypostatization of the meaning-species (§31: "the seven regular solids are, logically speaking, seven objects precisely as the seven sages are" — ideal objects without a heavenly place).

Stakes

Two intra-corpus fault lines run through this page. (1) Against Husserl's own future: §35's contingency-of-expression is the exact antithesis of the Origin of Geometry's thesis that ideal objectivity requires its Sprachleib and writing (ideal-objectivity) — the un-instituted pole of the wiki's stiftung/sedimentation genealogy (claim candidate li-static-vs-instituted-ideality, routed to the audit Harvest). (2) Against the MP corpus: MP's mature reading makes ideality emerge "at the edge of speech," intersubjectively and simultaneously with language (merleau-ponty-2002-husserl-limits) — a targeted double inversion of §8's solitary locus and §35's priority-claim; indirect-language's "the idea of a complete expression is nonsensical" negates precisely §28's "unbounded range of objective reason."

The Vol. II Completions (2026-07-21)

Two of this page's structural debts were paid by the Vol. II ingest. (1) The instance-side of the species-doctrine: Inv V §21 supplies what §31 left unanalysed — the concrete correlate of the meaning-species is the act's semantic essence (quality + matter, functioning expressively): "the ideational abstraction of this essence yields a 'meaning' in our ideal sense," with Husserl's own back-reference to Inv I §12's identity-series (see intentionality). The instantiation relation is thereby located (meaning : semantic essence :: Redness : this red moment), though the relation itself remains self-evidence-secured — the methexis parallel below stands. (2) The occasional-expressions relocation confirmed: Inv VI §5 revises §26's hearer-based indicating/indicated analysis ("from the first the speaker enjoys the 'indicated' meaning") and concedes that perception "determines, but does not embody" the meaning of "this" — the pointing-act account; the full generalization (all empirical predication occasional) arrives only in the 2nd-ed Foreword's retrospect, as this page already records. Additionally, pure-grammar supplies the combination-laws of the ideal meanings whose ontology this page states (Inv IV: semantic categories, Unsinn/Widersinn — §12's "round square" redeploys §15's objectlessness-≠-meaninglessness), and fulfilment supplies their epistemology (meaning empty without intuitive fulfilment; the "unbounded range of objective reason" priced at Inv VI §29: adequation never reached for external things).

Open Questions

~~Is the indicating/indicated analysis of "I" (§26) a solution or a relocation of the problem?~~ (Confirmed a relocation at Inv VI §5 — see The Vol. II Completions; the residual question is whether the pointing-act account escapes the original difficulty or renames it.)
What exactly is the instantiation relation between meaning-species and act-moment? Inv V §21 locates the instance (the semantic essence) but the relation stays secured by self-evidence — structurally parallel to the methexis the Phaedo leaves undefined (see ideal-species, theory-of-forms).
Does the §34 thesis (meaning lived through, not objectified) survive the §29 program (logic as science of meanings, which must objectify them wholesale)?
