“ III. I have often wondered how it should come to pass, that every man loving himself best, should more regard other men's opinions concerning himself than his own. ”

“If then thou shalt separate from thyself, that is from thy mind, whatsoever other men either do or say, or whatsoever thou thyself hast heretofore either done or said; and all troublesome thoughts concerning the future, and whatsoever, (as either belonging to thy body or life:) is without the jurisdiction of thine own will, and whatsoever in the ordinary course of human chances and accidents doth happen unto thee; so that thy mind (keeping herself loose and free from all outward coincidental entanglements; always in a readiness to depart:) shall live by herself, and to herself, doing that which is just, accepting whatsoever doth happen, and speaking the truth always; if, I say, thou shalt separate from thy mind, whatsoever by sympathy might adhere unto it, and all time both past and future, and shalt make thyself in all points and respects, like unto Empedocles his allegorical sphere, 'all round and circular,' &c., and shalt think of no longer life than that which is now present: then shalt thou be truly able to pass the remainder of thy days without troubles and distractions; nobly and generously disposed, and in good favour and correspondency, with that spirit which is within thee.
III. I have often wondered how it should come to pass, that every man loving himself best, should more regard other men's opinions concerning himself than his own. For if any God or grave master standing by, should command any of us to think nothing by himself but what he should presently speak out; no man were able to endure it, though but for one day. Thus do we fear more what our neighbours will think of us, than what we ourselves.” source
