 We can only have objective experience of particular events, for Kant, in so far as we simultaneously construct particular causal relations among them step by step, and this is only possible, in turn, in so far as we presuppose that they are one and all parts of a unified and uniform experience of nature in space and time governed by the Analogies of Experience (together with the other principles of pure understanding). Moreover, since particular causal relations, for Kant, necessarily involve causal laws, all of our inferences from particular perceptions to universal causal laws of nature are grounded in synthetic a priori principles of pure understanding providing a synthetic a priori conception of the unity and uniformity of nature in general. Hume was correct, therefore, that the principle of the uniformity of nature governs all of our inductive causal inferences; and he was also correct that this principle is not and cannot be analytic a priori. What Hume did not see, from Kant’s point of view, is that the merely comparative universality of inductive generalization can indeed be overcome by transforming initially merely subjective “empirical rules” into truly objective and necessary “universal laws” in accordance with synthetic but still a priori principles of the unity of nature in  general.[52]
