Gottlob Frege

German logician (1848–1925), founder of modern quantificational logic and — with Bolzano behind him — "the grandfather" of analytic philosophy (Dummett). He enters the wiki through his double relation to Husserl in the Logical Investigations era: as the reviewer whose "acerbic" 1894 notice of the Philosophy of Arithmetic accused Husserl of psychologism, and as the terminological road Husserl saw and declined.

Key Points

  • The 1894 review: Frege charged that Husserl confused numbers with presentations of numbers, "collapsing together truth and judging something as true" (Moran's editorial account in husserl-1900-logical-investigations-vol1). Relations, previously cordial (correspondence 1891, again 1906), broke off for a decade.
  • The single citation: in the whole Prolegomena, Frege appears exactly once — the endnote to §45: "I no longer approve of my own fundamental criticisms of Frege's antipsychologistic position set forth in my Philosophie der Arithmetik," now approving the Grundlagen der Arithmetik (1884) and the Preface to the Grundgesetze (1893). The retraction marks Husserl's break with his own 1891 psychologism — while the Foreword's conversion-narrative is internal (the psychological method's breakdown before "the unity of theory"), and Dummett's Preface records that the Frege-influence thesis is "widely believed… albeit some reject this conjecture." The wiki should not assert the "Frege converted Husserl" story as the book's own.
  • Sinn/Bedeutung declined: Inv I §15 cites Über Sinn und Bedeutung and declines the split — Husserl keeps Bedeutung, Sinn (and Meinung) equivalent "since it is at variance with ordinary German usage" (restricting Bedeutung to linguistic meaning only later, Ideas I §124 per Moran). LI-era terminology is deliberately non-Fregean — a philological guard for any Husserl–Frege comparison drawn from this corpus.
  • Convergence at 1900: Dummett's Preface argues that at the Logical Investigations' publication the two "did not… appear any great distance apart" — both anti-psychologistic, both holding logic non-normative at bottom (laws of truth, resting on the theoretical) — and that the analytic/phenomenological divergence came after. Husserl remained suspicious of purely formal-symbolic logic as "a refinement of logical technique rather than… a genuine philosophy of logic" (Moran).

Connections

  • contests psychologism — independently of and before the Prolegomena; Husserl's §45 note aligns the two campaigns retroactively.
  • contrasts with ideality-of-meaning — Husserl's meaning-as-species and declined Sinn/Bedeutung split mark the LI-era boundary between the two semantics.
  • is flanked by bernard-bolzano — the shared ancestor ("great-grandfather" of the analytic school, per Dummett) whom Husserl credits far more loudly than Frege.

Open Questions

  • The Husserl–Frege influence question (Mohanty vs Dummett camps, per Moran's notes) is reception-literature territory — not adjudicable from this corpus; ingest candidates: Frege's review (1894), Mohanty's Husserl and Frege.
