For some natures, changing their opinions is just as much a requirement of cleanliness as changing their clothes: for others, however, it is merely a requirement of vanity.
The majority of mankind is lazyminded, incurious, absorbed in vanities, and tepid in emotion, and is therefore incapable of either much doubt or much faith.
Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil. They give us, now and then, some of those luxurious sterile emotions that have a certain charm for the weak.... They are simply cheques that men draw on a bank where they have no account.
He who denies his own vanity usually possesses it in so brutal a form that he instinctively shuts his eyes to avoid the necessity of despising himself.
The most vulnerable and yet most unconquerable of things is human vanity; nay, through being wounded its strength increases and can grow to giant proportions.
To be beneficent when we can is a duty; and besides this, there are many minds so sympathetically constituted that, without any other motive of vanity or self-interest, they find a pleasure in spreading joy around them, and can take delight in the satisfaction of others so far as it is their own work. But I maintain that in such a case an action of this kind, however proper, however amiable it may be, has nevertheless no true moral worth, but is on a level with other inclinations. . . . For the maxim lacks the moral import, namely, that such actions be done from duty, not from inclination.
