Kant, and Causal Law

Introduction
In the critique of pure reason, Kant states, “All alternations occur in accordance with the law of the connection of cause and effect.”1 This statement is interpreted in two different ways: weak readings and strong readings. Weaker readings basically suggest that Kant's statement only refers to “All events have a cause”; however, the strong readings suggest that “the Second Analogy is committed not just to causes, but to causal laws as well.”2 To understand the difference between the readings, it is helpful to notice Kant's distinction between empirical laws of nature and universal transcendental principles. Empirical laws have an empirical element that universal transcendental principles cannot imply. On the other hand, empirical experiences require necessity to become a law, accordingly, “the transcendental laws “ground” the empirical laws by supplying them with their necessity.”3In this paper, according to this distinction, I first, argue that the second analogy supports the weak reading, second, show how in Prolegomena he uses the concept of causation in a way that is compatible to the strong reading, and third, investigate whether this incongruity is solvable.

Hume's Critique
In the preface of the Prolegomena, Kant freely admits that David Hume is the one who “first interrupted [his] dogmatic slumber and gave [his] investigations in the field of speculative philosophy a completely different direction.” Hume famously attacked metaphysics by questioning the necessity of the general law of causality, which is “All events have a cause.”Kant believes that this objection applies to the whole category of understanding, and insist that the possibility of metaphysics entirely depends on this probl...

There are two possible interpretations for the causal rule: first, any rule that include causal dependence, and second, a rule that necessarily determines in a given situation which state happens next. The first one is what the weak reading would suggest, which reduce the causal law to “Every event has a cause,” and the second one is the strong reading and indicates that “events type A are the cause of events type B.” In the next section, I argue that the second reading is what Kant explains here.
