Socrates, seeing a great quantity of riches, jewels, and furniture carried in pomp through his city: "How many things," said he, "I do not desire!"--[Cicero, Tusc. Quaes., V. 32.]--Metrodorus lived on twelve ounces a day, Epicurus upon less; Metrocles slept in winter abroad amongst sheep, in summer in the cloisters of churches: "Sufficit ad id natura, quod poscit." ["Nature suffices for what he requires."--Seneca, Ep., 90.] Cleanthes lived by the labour of his own hands, and boasted that Cleanthes, if he would, could yet maintain another Cleanthes. If that which nature exactly and originally requires of us for the conservation of our being be too little (as in truth what it is, and how good cheap life may be maintained, cannot be better expressed than by this consideration, that it is so little that by its littleness it escapes the gripe and shock of fortune), let us allow ourselves a little more; let us call every one of our habits and conditions nature; let us rate and treat ourselves by this measure; let us stretch our appurtenances and accounts so far; for so far, I fancy, we have some excuse. Custom is a second nature, and no less powerful. What is wanting to my custom, I reckon is wanting to me; and I should be almost as well content that they took away my life as cut me short in the way wherein I have so long lived. I am no longer in condition for any great change, nor to put myself into a new and unwonted course, not even to augmentation. 'Tis past the time for me to become other than what I am; and as I should complain of any great good hap that should now befall me, that it came not in time to be enjoyed: "Quo mihi fortunas, si non conceditur uti?" ["What is the good fortune to me, if it is not granted to me to use it."--Horace, Ep., i. 5, 12.]
