In this video, Professor Thorsby walks through the first arguments of the "Logical Investigations" by Edmund Husserl.

Summary:

In this reading, Husserl offers a critique of the position of logical psychologism. The problem concerns the theoretical foundations upon which the validity of the sciences depend. All science psychology, physics, biology, etc. depend upon the validity of their reasoning. Taken in this way, logic can be understood as a normative discipline or technology that gets used by other sciences. Logic as its own science is an investigation into the principles that govern validity. Logic is dependent upon certain core methodological features. Or, as Husserl puts it, the normative technology of logic depends upon a theoretical foundation. Logicians of the 19th century had largely held that these theoretical foundations were empirically given as inductive forms of reasoning governed by psychological laws. (see Mill and Lipps). Husserl's work represents a sustained attack against the logical psychologist of this period in favor of an a priori theoretical foundation. Put in historical context, Husserl's own philosophical position is much closer to the position of Immanuel Kant. Historically, this text nicely illustrates the continued tension between the tradition of English empiricism and German idealism.
