In the 1890's, when fields such as psychology and philosophy were just emerging, turf wars between the disciplines were common-place. Philosophers widely discounted the possibility that psychology's claim to empirical truth had anything relevant to offer their field. And psychologists, such as the crazed and eccentric Otto Weinegger, often considered themselves philosophers. Freud, it is held, was deeply influenced by his wife, Martha's, uncle, who was also a philosopher. The tension between the fields persisted, until the two fields eventually matured and grew apart. Until the publication of Martin Kursch's masterly work Psychologism , few philosophers and psychologists have attended to their originally unhappy, turn-of-the-century engagement. Martin Kusch explores the origins of psychologism in Germany and fin de siecle Vienna by examining two major figures of twentieth century philosophy: Frege and Husserl. As one of the few serious works on Frege, Kusch trenchantly and clearly reconstructs the debate and the context in which it flourished. Psychologism will prove to be a key work of intellectual history on a subject which has largely been overlooked and, above all, understudied.

An influential interpretation of phenomenology construes Husserl's project as an attempt to generalize the Fregean notion of sense- an attempt to extend Frege's analysis of the structure of meaningful expressions to a more general account of the structure of meaning in experience . Michael Dummett has articulated a broadly Fregean critique of this Husserlian program, arguing that the project is misguided and retrograde-a relapse into the psychologism and idealism that Frege sought to avoid. A defense of Husserl is offered, based in part on key elements of the theory of meaning articulated in his Logical Investigations . But the main aim is neither to acquit nor to convict Husserl of Dummett's charges; rather it is to use the exchange to investigate some of the philosophical commitments of a broadly Husserlian phenomenology. If we are to understand how Husserl avoids psychologism then we must come to terms with the paradoxical idea of an anti-psychologistic investigation of consciousness (an anti-psychologistic psychology). If we are to understand his complex stance toward idealism then we must not only understand the grounds for his rejection of subjective idealism but also be attuned to the other forms of idealism to which his project is committed. In the course of investigating these matters the author considers how Husserl can reply to the charge of explanatory vacuity, and shows that Frege himself recognizes the legitimacy of something like the Husserlian project.

ESSAY HUSSERL, FREGE AND THE OVERCOMING OF PSYCHOLOGISM* I In a letter to Marvin Farber, Husserl wrote, "External 'influences' are without significance . ...

Psychologism in logic holds that logic is a branch of psychology. This view has been vigorously defended by John Stuart Mill and by a number of German philosophers of logic, notably Erdmann. Its chief critics have been Husserl and Frege and, to a lesser extent, Russell. Husserl set forth a profound and detailed critique of psychologism in Logical Investigations. This paper examines this critique. First, I explain why the psychologistic theory is attractive. Then I show that Husserl's critique is not convincing, partly because he does not take the theory in its most plausible form and partly because he ignores certain important distinctions (for example, between what a statement is about and what it is true in virtue of). Then I raise two new objections to the psychologistic theory. The purpose of this paper is to suggest that the psychologistic theory remains an important and serious position from which we can learn much about the status of logic.

By tracing the general evolution of HusserI’s theory of logic and mathematics, this essay explores Husserl’s identification and strategic overcoming of the two forms of psychologism--Iogical psychologism and transcendental psychologism--that bar the way to rigorous phenomenological inquiry. In the early works “On the Concept of Number” and the Philosophie der Arithmetik Husserl himself falls victim to a particular form of logical psychologism. By the time of the Logical Investigations this problem has been dealt with: the method of eidetic intuition enables an account of the “origins” of logical and mathematical concepts without reducing such concepts to mere predicates of mental acts. The task of Formal and Transcendental Logic is to disclose the more pervasive problem of transcendental psychologism, one that taints even the theory of pure logic articulated in the Logical Investigations. A radical solution is provided through the development of an “ultimate logic” of transcendental subjectivity.
