For my own part, I cannot but think that an ordinary mechanic—for instance, a maker of musical instruments —would be much more attentive and pleased at his work, if he knew that his harp would be touched by the famous Amphion, and in his hand serve for the builder of Thebes, or if that Thales had bespoke it, who was so great a master that by the force of his music he pacified a popular tumult amongst the Lacedaemonians. A good-natured shipwright would ply his work more heartily, if he were making the steerage for the admiral galley of Themistocles when he fought for the liberty of Greece, or of Pompey when he went on his expedition against the pirates: what ecstasy of delight then must a philosopher be in, when he reflects that his scholar is a man of authority, a prince or great potentate, that he is employed in so public a work, giving laws to him who is to give laws to a whole nation, who is to punish vice, and to reward the virtuous with riches and honor? The builder of the Argo certainly would have been mightily pleased, if he had known what noble mariners were to row in his ship, and that at last she should be translated into heaven; and a carpenter would not be half so much pleased to make a coach or plough, as to make the tablets on which Solon’s laws were to be engraved. In like manner the discourses and rules of philosophy, being once deeply stamped and imprinted on the minds of great personages, will stick so close, that the prince shall seem no other than justice incarnate and animated law. This was the design of Plato’s voyage into Sicily,—he hoped that the lectures of his philosophy would serve for laws to Dionysius, and bring his affairs again into a good posture. But the soul of that unfortunate prince was like paper scribbled all over with the characters of vice; its piercing and corroding quality had stained quite through, and sunk into the very substance of his soul. Whereas, if such persons are to profit by sage lessons, they must be taken when they are at full speed.
