Editing Critique of Practical Reason (section)

==Dialectic: Chapter One==
Pure reason, in both its theoretical and practical forms, faces the fundamental problem that things in the phenomenal realm of experience are conditional (i.e. they depend on something else) but pure reason always seeks for the unconditional. The solution to this is that the unconditional, according to Kant, is only to be found in the noumenal world. Pure theoretic reason, when it attempts to reach beyond its limits into the unconditional is bound to fail and the result is the creation of [[antinomy|antinomies]] of reason.

Antinomies are conflicting statements both of which appear to be validated by reason. Kant exposed several such antinomies of speculative reason in the first Critique. In the second Critique, he finds an antinomy of pure practical reason whose resolution is necessary in order to further our knowledge.

In this case, the antinomy consists in the fact that the object of pure practical reason must be the highest good (''[[Summum bonum]]''). Good actions depend on the highest good to make them worthwhile. However, assuming the existence of a highest good leads to paradox and assuming the non-existence of a highest good also leads to paradox.
