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.
The need for sociability induce man to be in touch with his fellow men. However, this need might not ("ne saurait", Fr.) find its full (or complete) satisfaction in the conventional (or superficial, - "conventionnel", Fr.) and deceitful world, in which (or where) everyone is mainly (or mostly) trying to assert oneself in front of others ("devant les autres", Fr.), to appear, and hoping to find in society ("mondaine", Fr.) relationships some advantages for his interest and vanity (or vainglory or conceit", Fr).

She was heartily ashamed of her ignorance - a misplaced shame. Where people wish to attach, they should always be ignorant. To come with a well−informed mind is to come with an inability of administering to the vanity of others, which a sensible person would always wish to avoid.

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.
