text: Now that which Panaetius replied to the question about love may be applied, I believe, to all the emotions. In so far as we are able, let us step back from slippery places; even on dry ground it is hard enough to take a sturdy stand. At this point, I know, you will confront me with that common complaint against the Stoics: "Your promises are too great, and your counsels too hard. We are mere manikins, unable to deny ourselves everything. We shall sorrow, but not to any great extent; we shall feel desires, but in moderation; we shall give way to anger, but we shall be appeased." And do you know why we have not the power to attain this Stoic ideal? It is because we refuse to believe in our power. Nay, of a surety, there is something else which plays a part: it is because we are in love with our vices; we uphold them and prefer to make excuses for them rather than shake them off. We mortals have been endowed with sufficient strength by nature, if only we use this strength, if only we concentrate our powers and rouse them all to help us or at least not to hinder us. The reason is unwillingness, the excuse, inability. Farewell.
