He that lives well in the world is better than he that lives well in a monastery. But perhaps everyone is not able to stem the temptations of public life, and if he cannot conquer he may properly retreat.
 Samuel Johnson, The History of Rasselas, Prince of Abissinia (1759). copy citation

Context

“May not he equally hope for future happiness who converses openly with mankind, who succours the distressed by his charity, instructs the ignorant by his learning, and contributes by his industry to the general system of life, even though he should omit some of the mortifications which are practised in the cloister, and allow himself such harmless delights as his condition may place within his reach? ” “ This, ” said Imlac, “ is a question which has long divided the wise and perplexed the good. I am afraid to decide on either part. He that lives well in the world is better than he that lives well in a monastery. But perhaps everyone is not able to stem the temptations of public life, and if he cannot conquer he may properly retreat. Some have little power to do good, and have likewise little strength to resist evil. Many are weary of the conflicts with adversity, and are willing to eject those passions which have long busied them in vain.” source
