49. For the wealth, say they, of nature is definite, and easily obtained; but that which proceeds from vain opinions, is indefinite, and procured with difficulty. For things which may be readily obtained, remove in a beautiful and abundantly sufficient manner that which, through indigence, is the cause of molestation to the flesh; and these are such as have the simple nature of moist and dry aliments. But every thing else, say they, which terminates in luxury, is not attended with a necessary appetition, nor is it necessarily produced from a certain something which is in pain; but partly arises from the molestation and pungency solely proceeding from something not being present; partly from joy; and partly from vain and false dogmas, which neither pertain to any natural defect, nor to the dissolution of the human frame, those not being present. For things which may every where be obtained, are sufficient for those purposes which nature necessarily requires. But these, through their simplicity and paucity, may be easily procured. And he, indeed, who feeds on flesh, requires also inanimate natures; but he who is satisfied with things inanimate, is easily supplied from the half of what the other wants, and needs but a small expense for the preparation of his food. 50. They likewise say, it is requisite that he who prepares the necessaries of life, should not afterwards make use of philosophy as an accession; but, having obtained it, should, with a confident mind, thus genuinely endure[33] the events of the day. For we shall commit what pertains to ourselves to a bad counsellor, if we measure and procure what is necessary to nature, without philosophy. Hence it is necessary that those who philosophize should provide things of this kind, and strenuously attend to them as much as possible. But, so far as there is a dereliction from thence, [_i.e._ from philosophizing], which is not capable of effecting a perfect purification[34], so far we should not endeavour to procure either riches or nutriment. In conjunction, therefore, with philosophy, we should engage in things of this kind, and be immediately persuaded that it is much better to pursue what is the least, the most simple, and light in nutriment. For that which is least, and is unattended with molestation, is derived from that which is least[35].
