And where there is ignorance, there is also want of learning and instruction in essentials. - Epictetus

He did not say, 'Define me envy', and then, when the man defined it, 'You define it ill, for the terms of the definition do not correspond to the subject defined.' Such phrases are technical and therefore tiresome to the lay mind, and hard to follow, yet you and I cannot get away from them. We are quite unable to rouse the ordinary man's attention in a way which will enable him to follow his own impressions and so arrive at admitting or rejecting this or that. And therefore those of us who are at all cautious naturally give the subject up, when we become aware of this incapacity; while the mass of men, who venture at random into this sort of enterprise, muddle others and get muddled themselves, and end by abusing their opponents and getting abused in return, and so leave the field. But the first quality of all in Socrates, and the most characteristic, was that he never lost his temper in argument, never uttered anything abusive, never anything insolent, but bore with abuse from others and quieted strife.

Your aim should be to view the world as an integrated whole, to faithfully incline your whole being toward the highest good, and to adopt the will of nature as your own.

Whatever moral rules you have deliberately proposed to yourself. abide by them as they were laws, and as if you would be guilty of impiety by violating any of them. Don’t regard what anyone says of you, for this, after all, is no concern of yours.
