Prolegomena to Any Future Metaphysics That Will Be Able to Present Itself as a Science () is a book by the German philosopher Immanuel Kant, published in 1783, two years after the first edition of his "Critique of Pure Reason". One of Kant's shorter works, it contains a summary of the "Critique"‘s main conclusions, sometimes by arguments Kant had not used in the "Critique". Kant characterizes his more accessible approach here as an "analytic" one, as opposed to the "Critique"‘s "synthetic" examination of successive faculties of the mind and their principles.
