"If you have an earnest desire towards philosophy, prepare yourself from the very first to have the multitude laugh and sneer, and say, "He is returned to us a philosopher all at once; "and "Whence this supercilious look?" Now, for your part, do not have a supercilious look indeed; but keep steadily to those things which appear best to you, as one appointed by God to this particular station.

When therefore we are hindered, or disturbed, or grieved, let us never attribute it to others, but to ourselves; that is, to our own principles. An uninstructed person will lay the fault of his own bad condition upon others. Someone just starting instruction will lay the fault on himself. Some who is perfectly instructed will place blame neither on others nor on himself.

Taking account of the value of externals, you see, comes at some cost to the value of one's own character.
