Kant sought throughout his life to provide a philosophy adequate to the sciences of his time—especially Euclidean geometry and Newtonian physics. In this new book, Michael Friedman argues that Kant’s continuing efforts to find a metaphysics that could provide a foundation for the sciences is of the utmost importance in understanding the development of his philosophical thought from its earliest beginnings in the thesis of 1747, through the Critique of Pure Reason, to his last unpublished writings in the Opus postumum.
