["But unless the mind is purified, what internal combats and dangers must we incur in spite of all our efforts!  How many bitter anxieties, how many terrors, follow upon unregulated passion!  What destruction befalls us from pride, lust, petulant anger!  What evils arise from luxury and sloth!”—­Lucretius, v. 4.]

Our disease lies in the mind, which cannot escape from itself;

          “In culpa est animus, qui se non effugit unquam,”
          —­Horace, Ep., i. 14, 13.

and therefore is to be called home and confined within itself:  that is the true solitude, and that may be enjoyed even in populous cities and the courts of kings, though more commodiously apart.

Now, since we will attempt to live alone, and to waive all manner of conversation amongst them, let us so order it that our content may depend wholly upon ourselves; let us dissolve all obligations that ally us to others; let us obtain this from ourselves, that we may live alone in good earnest, and live at our ease too.

Stilpo having escaped from the burning of his town, where he lost wife, children, and goods, Demetrius Poliorcetes seeing him, in so great a ruin of his country, appear with an undisturbed countenance, asked him if he had received no loss?  To which he made answer, No; and that, thank God, nothing was lost of his.—­[Seneca, Ep. 7.]—­This also was the meaning of the philosopher Antisthenes, when he pleasantly said, that “men should furnish themselves with such things as would float, and might with the owner escape the storm";—­[Diogenes Laertius, vi. 6.] and certainly a wise man never loses anything if he have himself.  When the city of Nola was ruined by the barbarians, Paulinus, who was bishop of that place, having there lost all he had, himself a prisoner, prayed after this manner:  “O Lord, defend me from being sensible of this loss; for Thou knowest they have yet touched nothing of that which is mine.”—­[St. Augustin, De Civit.  Dei, i. 10.]—­The riches that made him rich and the goods that made him good, were still kept entire.  This it is to make choice of treasures that can secure themselves from plunder and violence, and to hide them in such a place into which no one can enter and that is not to be betrayed by any but ourselves.  Wives, children, and goods must be had, and especially health, by him that can get it; but we are not so to set our hearts upon them that our happiness must have its dependence upon them; we must reserve a backshop, wholly our own and entirely free, wherein to settle our true liberty, our principal solitude and retreat.  And in this we must for the most part entertain ourselves with ourselves, and so privately that no exotic knowledge or communication be admitted there; there to laugh and to talk, as if without wife, children, goods, train, or attendance, to the end that when it shall so fall out that we must lose any or all of these, it may be no new thing to be without them.  We have a mind pliable in itself, that will be company; that has wherewithal to attack and to defend, to receive and to give:  let us not then fear in this solitude to languish under an uncomfortable vacuity.
