To do nothing is in everyone's power.

In traveling, a man must carry knowledge with him, if he would bring home knowledge.

The gratification which affluence of wealth, extent of power, and eminence of reputation confer, must be always, by their own nature, confined to a very small number; and the life of the greater part of mankind must be lost in empty wishes and painful comparisons, were not the balm of philosophy shed upon us, and our discontent at the appearances of unequal distribution soothed and appeased.

No wise man will go to live in the country, unless he has something to do which can be better done in the country. For instance, if he is to shut himself up for a year to study science, it is better to look out to the fields, than to an opposite wall. Then, if a man walks out in the country, there is nobody to keep him from walking in again: but if a man walks out in London, he is not sure when he will walk in again. A great city is, to be sure, the school for studying life.

The happiest part of a man's life is what he passes lying awake in bed in the morning.

The first step to greatness is to be honest.

By the consultation of books, whether of dead or living authors, many temptations to petulance and opposition, which occur in oral conferences, are avoided. An author cannot obtrude his service unasked, nor can be often suspected of any malignant intention to insult his readers with his knowledge or his wit. Yet so prevalent is the habit of comparing ourselves with others, while they remain within the reach of our passions, that books are seldom read with complete impartiality, but by those from whom the writer is placed at such a distance that his life or death is indifferent.
