One can bring no greater reproach against a man than to say that he does not set sufficient value upon pleasure, and there is no greater sign of a fool than the thinking that he can tell at once and easily what it is that pleases him. To know this is not easy, and how to extend our knowledge of it is the highest and most neglected of all arts and branches of education. Indeed, if we could find its springs, it inception and earliest modus operandi, we should have discovered the very secret of life and development of every sense from touch onwards, and no new sense was ever developed without pains. A man had better stick to known and proved pleasures, but, if he will venture in quest of new ones, he should not do so with a light heart. One reason why we find it so hard to know our own likings is because we are so little accustomed to try: we have our likings found for us in respect of by far the greater number of all the matters that concern us; thus we have grown all our limbs on the strength of the likings of our ancestors and adopt these without question. Another reason is that, except in mere matters of eating and drinking, people do not realize the importance of finding out what it is that gives them pleasure of, that is to say, they would make themselves as comfortable here as they reasonably can. very few, however, seem to are greatly whether they are comfortable or not. These are some men so ignorant and careless of what gives them pleasure that they cannot be said ever to have been really born as living beings at all.
