Section 14: True Leisure Belongs To The Wise explained simply

XIV. The only persons who are really at leisure are those who devote themselves to philosophy: and they alone really live: for they do not merely enjoy their own lifetime, but they annex every century to their own: all the years which have passed before them belong to them. Unless we are the most ungrateful creatures in the world, we shall regard these noblest of men, the founders of divine schools of thought, as having been born for us, and having prepared life for us: we are led by the labour of others to behold most beautiful things which have been brought out of darkness into light; we are not shut out from any period, we can make our way into every subject, and, if only we can summon up sufficient strength of mind to overstep the narrow limit of human weakness, we have a vast extent of time wherein to disport ourselves: we may argue with Socrates, doubt with Carneades, repose with Epicurus, overcome human nature with the Stoics, out-herod it with the Cynics. Since Nature allows us to commune with every age, why do we not abstract ourselves from our own petty fleeting span of time, and give ourselves up with our whole mind to what is vast, what is eternal, what we share with better men than ourselves? Those who gad about in a round of calls, who worry themselves and others, after they have indulged their madness to the full, and crossed every patron’s threshold daily, leaving no open door unentered, after they have hawked about their interested greetings in houses of the most various character,—after all, how few people are they able to see out of so vast a city, divided among so many different ruling passions: how many will be moved by sloth, self-indulgence, or rudeness to deny them admittance: how many, after they have long plagued them, will run past them with feigned hurry? how many will avoid coming out through their entrance-hall with its crowds of clients, and will escape by some concealed backdoor? as though it were not ruder to deceive their visitor than to deny him admittance!—how many, half asleep and stupid with yesterday’s debauch, can hardly be brought to return the greeting of the wretched man who has broken his own rest in order to wait on that of another, even after his name has been whispered to them for the thousandth time, save by a most offensive yawn of his half-opened lips. We may truly say that those men are pursuing the true path of duty, who wish every day to consort on the most familiar terms with Zeno, Pythagoras, Democritus, and the rest of those high priests of virtue, with Aristotle and with Theophrastus. None of these men will be “engaged,” none of these will fail to send you away after visiting him in a happier frame of mind and on better terms with yourself, none of them will let you leave him empty-handed: yet their society may be enjoyed by all men, and by night as well as by day.
