For this accession, then, pure theoretical reason,
for which all those ideas are transcendent and without object, has
simply to thank its practical faculty.

Question:

How do pure and practical faculties coalesce?

Answer (optional):

Pure and practical faculties coalesce through the use of an apodeictic practical law, which allows (transcendent) thoughts to acquire objective reality. While these thoughts do not form any synthetical judgement about the objects, or help in determining their theoretical application, they help in the enlargement of the theoretical knowledge of reason. When these ideas become the source of the possibility of realizing the necessary object of pure practical reason - the summum bonum - they can be said to have become immanent and constitutive, rather than remaining transcendent, and merely regulative principles of speculative reason. This is made possible by the practical faculty of reason, which helps stay clear of anthropomorphism and fanaticism, thus acting as an aid to the practical use of pure reason.
