ABSTRACT
Approaching the conclusion of his monumental Critique of Pure Reason, Immanuel Kant observes:
All the interests of my reason, speculative as well as practical, combine in the three following questions:
What can I know?
What ought I to do?
What may I hope?
The first question is merely speculative. We have, as I flatter myself, exhausted all the possible answers to it, and at last have found the answer with which reason must perforce content itself, and with which, so long as it takes no account of the practical, it has also good cause to be satisfied. 1
