Though Kant himself would undoubtedly have thought it a scandal that differing interpretations of his Critique of Pure Reason would continue to be given well into the twentieth century, the fact may be that it is less a scandal than a testament to the richness, depth and enduring vitality of his thought. In any case several major books on the first Critique have appeared within the last few years. D. P. Dryer's Kant's Solution for Verification in Metaphysics is one of the most substantial.
