In the Metaphysical Foundations of Natural Science, Kant’s project is to provide the metaphysical basis for a proper science of matter. What he calls a special metaphysics of corporeal nature involves determining the powers, properties, and laws of matter. These include the fundamental forces of attraction and repulsion, along with their laws of diffusion (treated in the Dynamics chapter), and the three laws of mechanics (treated in the Mechanics chapter). In the preface, Kant indicates that the pure intuition of space (MAN, 4:472) and the “form and principles of outer intuition” have a crucial (though not yet specified) role to play in his project (MAN, 4:478).
