Live peaceably with all mankind, if you can; but, as you cannot, endeavor, as the next best thing, to settle all disputes as speedily as possible, by coming, without loss of time, to blows; provided always that the debate promises to be terminated, by reason of your superior strength, in your own favour, and that you are not likely to be taken up for knocking another person down.  It is very true that I, individually, never shun this kind of discussion, whatever may be the strength and pretensions of my opponent; but then, I enjoy a consciousness of superiority over the whole world, which you, perhaps, may not feel, and which might, in some cases, mislead you.  I think, however, that a supreme contempt for all but yourselves is a very proper sentiment to entertain; and, from what I observe of the conduct of certain teachers, I imagine that this is what is meant by the word humility.  You must, nevertheless, be careful how you display it; do so only when you see a probability of overawing and frightening those around you, so as to make them contributors to the great aim of your existence—­self-gratification.

Be firm, but not obstinate.  Never change your mind when the result of the alteration would be detrimental to your comfort and interest; but do not maintain an inconvenient inflexibility of purpose.  Do not, for instance, in affairs of the heart, simply because you have declared, perhaps with an oath or two, that you will be constant till death, think it necessary to make any effort to remain so.  The case stands thus:  you enter into an agreement with a being whose aggregate of perfections is expressible, we will say, by 20.  Now, if they would always keep at that point, there might be some reason for your remaining unaltered, namely, your not being able to help it.  But suppose that they dwindle down to 19-1/2, the person, that is, the whole sum of the qualities admired, no longer exists, and you, of course, are absolved from your engagement.  But mind, I do not say that you are justified in changing only in case of a change on the opposite side:  you may very possibly become simply tired.  In this case, your prior promise to yourself will absolve you from the performance of the one in question.

And now, my good friends, before we part, let me beg of you not to allow yourselves to be diverted from the right path by a parcel of cant.  You will hear my system stigmatised as selfish; and I advise you, whenever you have occasion to speak of it in general society, to call it so too.  You will thus obtain a character for generosity; a very desirable thing to have, if you can get it cheap.  Selfish, indeed! is not self the axis of the earth out of which you were taken?  The fact is, good people, that just as notions the very opposite of truth have prevailed in matters of science, so have they, likewise, in those of morals.  A set of impracticable doctrines, under the name of virtue, have been preached up by your teachers; and it is only fortunate that they have been practised by so few; those few having been, almost to a man, poisoned, strangled, burnt, or worse treated, for their pains.
