Neighbourhoods and Intersubjectivity

Back to Kant! QBism, Phenomenology, and Reality from Invariants

“…advertise below. Third, it is not clear just how close Weyl's attachment to phenomenology really is, as pointed out, e.g., by Bernard and Lobo (2019) or Sieroka (2019), and underscored by Weyl's self-admitted interest in thinkers such as Fichte, Plato, Hume and others. 15 Finally, even if geometry was a field in which the phenomenological method could be put to good use, it remains unclear to me whether the same is true of quantum physics-wherein "Evidenz" and "Anschaulichkeit" (Ryckman, 2007, § 5.4.1; § 6.3.1) clearly become touchy subjects (however, see French, 2020, in this connection).…”

Connecting the Revolutionary with the Conventional: Rethinking the Differences between the Works of Brouwer, Heyting, and Weyl

“…Solomon Feferman argued that Weyl's criticism of the set-theoretical approach led him to embrace a predicativist position in Das Kontinuum (Weyl 1918;see Feferman [1988] for further discussion). Erhard Scholz describes Weyl's inclination toward intuitionism as rooted in philosophical considerations deeply influenced by Fichte's approach to the concept of continuum and space (Scholz 2000), whereas Norman Sieroka claims that during the 1920s, Husserl's phenomenology motivated Weyl to adopt Brouwer's intuitionism, and Fichte's constructivism motivated him to adopt formalism-which explains why, after his brief affiliation with Husserl's "intuitionistic-phenomenological" approach, from 1925 Weyl's foundational views drifted toward Fichte's "formalistic-constructivist" approach (Sieroka 2009(Sieroka , 2019.…”

“…Brouwer shared a similar impression with Kant's approach to the apriority of time and dedicated the second chapter of his dissertation to improving Kant's view of the a priori (Brouwer 1907, 99-131). During the 1910s, Weyl was attracted to idealist philosophy, specifically to the works of Husserl and Fichte, which played a significant role in his foundational thought and the development of his inclination toward constructive approaches and, later, toward Brouwer's intuitionistic ideas (Scholz 2005;Sieroka 2009Sieroka , 2019. Because Weyl's metaphysical outlook included some realistic aspects, his idealism was different from Brouwer's idealism because Brouwer's philosophy amounted virtually to solipsism, whereas Weyl still seemed to have cleaved to phenomenology 5 (Mancosu and Ryckman 2002;Bell and Korté 2015).…”
