Under the influence of the same error (for who could keep the right course when Cicero is in error?), Seneca said: “Philosophy is nothing else than the right method of living, or the science of living honourably, or the art of passing a good life. We shall not err in saying that philosophy is the law of living well and honourably. And he who spoke of it as a rule of life, gave to it that which was its due.” He evidently did not refer to the common name of philosophy; for, since this is diffused into many sects and systems, and has nothing certain—nothing, in short, respecting which all agree with one mind and one voice,—what can be so false as that philosophy should be called the rule of life, since the diversity of its precepts hinders the right way and causes confusion? or the law of living well, when its subjects are widely discordant? or the science of passing life, in which nothing else is effected by its repeated contradictions than general uncertainty? For I ask whether he thinks that the Academy is philosophy or not? I do not think that he will deny it. And if this is so, none of these things, therefore, is in agreement with philosophy; which renders all things uncertain, abrogates law, esteems art as nothing, subverts method, distorts rule, entirely takes away knowledge. Therefore all those things are false, because they are inconsistent with a system which is always uncertain, and up to this time explaining nothing. Therefore no system, or science, or law of living well, has been established, except in this the only true and heavenly wisdom, which had been unknown to philosophers. For that earthly wisdom, since it is false, becomes varied and manifold, and altogether opposed to itself. And as there is but one founder and ruler of the world, God, and as truth is one; so wisdom must be one and simple, because, if anything is true and good, it cannot be perfect unless it is the only one of its kind. But if philosophy were able to form the life, no others but philosophers would be good, and all those who had not learned it would be always bad. But since there are, and always have been, innumerable persons who are or have been good without any learning, but of philosophers there has seldom been one who has done anything praiseworthy in his life; who is there, I pray, who does not see that those men are not teachers of virtue, of which they themselves are destitute? For if any one should diligently inquire into their character, he will find that they are passionate, covetous, lustful, arrogant, wanton, and, concealing their vices under a show of wisdom, doing those things at home which they had censured in the schools.
