In A Realist Theory of Science, Roy Bhaskar provides several transcendental arguments for critical realism – a position Bhaskar himself characterized as transcendental realism. Bhaskar provides an argument from perception and from the intelligibility of scientific experimentation, maintaining that transcendental realism is necessary for both. I argue that neither argument succeeds, and that transcendental idealism can better vindicate scientific practice than Bhaskar’s realism. Bhaskar’s arguments against the Kantian view fail, for they misrepresent the transcendental idealist position. I conclude that, if (...) they wish to retain their theoretical commitments, critical realists ought to be transcendental idealists. (shrink)

In this article, I assess Tuukka Kaidesoja’s response to my objections to his critique of transcendental arguments and respond to his criticisms of my work. I argue that his new attempt to link transcendental arguments to Kant’s transcendental idealism is just as question-begging as his previous attempt, that his problematization of Bhaskar’s use of Kantian terminology is premised upon a confusion, and that his elaboration of explanatory necessity still fails to clearly distinguish it from transcendental necessity. I also elaborate and (...) defend my conception of transcendental arguments and the relative a priority it involves against Kaidesoja’s criticisms of them. While I concede the validity of his concerns about the starting point of Bhaskar’s transcendental analysis of experimental activity, I maintain that this does not undermine naturalized transcendentalism itself. I thus conclude that Kaidesoja’s metaphilosophical naturalism is premised upon a flawed critique of transcendentalism and an insufficiently motivated alternative approach. (shrink)
