Although most friendships that exist do not merit the name, we can nevertheless make use of them in accordance with our needs, as a kind of commercial venture based on uncertain foundations and in which we are very often deceived.

The conversation of those who like to lord it over us is very disagreeable. But we should always be ready to graciously acknowledge the truth, no matter in what guise it comes to us.

There is no one who cannot derive great help and great benefit from learning; but there are also only a few people who do not receive a great harm from the light and knowledge they have received by learning, unless they use their knowledge in a manner both fit and natural for them.

True merit does not depend on the times or on fashion. Those who have no other advantage than courtly manners lose it when they are away from court. But good sense, knowledge, and wisdom make their possessors knowledgeable and beloved in all ages and in all times.

There are people so blind and self-absorbed in all matters that they always believe that, whatever they desire or think, they can impose their will on other people. Whatever bad reason they use to persuade others, these self-centered people are so caught up in the process that it seems to them all they have to do is to speak their wishes in a lofty and commanding tone of voice in order to convince everybody.

We are more put off by people who parade their dignity than by people who show off their wardrobes. When people have to trick themselves out to gain attention, it is a sure sign that they are unworthy of it. If we want to make ourselves worthy, we can do so only by the innate eminence conferred by virtue. We hold great people in esteem more for the qualities of their soul than for the qualities of their fortune.

Although we should not love our friends for the good that they do us, it is a sign that they do not love us much if they do not do us good when they have the power to do so.
