If any man is able to convince me and show me that I do not think or act right, I will gladly change; for I seek the truth by which no man was ever injured. But he is injured who abides in his error and ignorance.
If a thing is in thy own power, why dost thou do it? But if it is in the power of another, whom dost thou blame? The atoms (chance) or the gods? Both are foolish. Thou must blame nobody. For if thou canst, correct that which is the cause; but if thou canst not do this, correct at least the thing itself; but if thou canst not do even this, of what use is it to thee to find fault? For nothing should be done without a purpose.
If thou art able, correct by teaching those who do wrong; but if thou canst not, remember that indulgence is given to thee for this purpose. And the gods, too, are indulgent to such persons; and for some purposes they even help them to get health, wealth, reputation; so kind they are. And it is in thy power also; or say, who hinders thee?
