SECTION 39. If you want your judgment to be accepted, express it
coolly and without passion. All violence has its seat in the will; and so, if your judgment is expressed with vehemence, people will consider it an effort of will, and not the outcome of knowledge, which is in its nature cold and unimpassioned. Since the will is the primary and radical element in human nature, and intellect merely supervenes as something secondary, people are more likely to believe that the opinion you express with so much vehemence is due to the excited state of your will, rather than that the excitement of the will comes only from the ardent nature of your opinion.
SECTION 40. Even when you are fully justified in praising yourself,
you should never be seduced into doing so. For vanity is so very common, and merit so very uncommon, that even if a man appears to be praising himself, though very indirectly, people will be ready to lay a hundred to one that he is talking out of pure vanity, and that he has not sense enough to see what a fool he is making of himself.
Still, for all that, there may be some truth in Bacon's remark that, as in the case of calumny, if you throw enough dirt, some of it will stick, so it it also in regard to self-praise; with the conclusion that self-praise, in small doses, is to be recommended.[44]
