text: My tardiness in answering your letter was not due to press of business. Do not listen to that sort of excuse; I am at liberty, and so is anyone else who wishes to be at liberty. No man is at the mercy of affairs. He gets entangled in them of his own accord, and then flatters himself that being busy is a proof of happiness. Very well; you no doubt want to know why I did not answer the letter sooner? The matter about which you consulted me was being gathered into the fabric of my volume. For you know that I am planning to cover the whole of moral philosophy and to settle all the problems which concern it. Therefore I hesitated whether to make you wait until the proper time came for this subject, or to pronounce judgment out of the logical order; but it seemed more kindly not to keep waiting one who comes from such a distance. So I propose both to pick this out of the proper sequence of correlated matter, and also to send you, without waiting to be asked, whatever has to do with questions of the same sort.
