*158* Nec verum est, quod dicitur a quibusdam, propter necessitatem vitae, quod ea, quae natura desideraret, consequi sine aliis atque efficere non possemus, idcirco initam esse cum hominibus communitatem et societatem; quodsi omnia nobis, quae ad victum cultumque pertinent, quasi virgula divina, ut aiunt, suppeditarentur, tum optimo quisque ingenio negotiis omnibus omissis totum se in cognitione et scientia collocaret. Non est ita; nam et solitudinem fugeret et socium studii quaereret, tum docere tum discere vellet, tum audire tum dicere. Ergo omne officium, quod ad coniunctionem hominum et ad societatem tuendam valet, anteponendum est illi officio, quod cognitione et scientia continetur.

And yet scholars, whose whole life and interests have been devoted to the pursuit of knowledge, have not, after all, failed to contribute to the advantages and blessings of mankind. For they have trained many to be better citizens and to render larger service to their country. So, for example, the Pythagorean Lysis taught Epaminondas of Thebes; Plato, Dion of Syracuse; and many, many others. As for me myself, whatever service I have rendered to my country--if, indeed, I have rendered any--I came to my task trained and equipped for it by my teachers and what they taught me. *156* And not only while present in the flesh do they teach and train those who are desirous of learning, but by the written memorials of their learning they continue the same service after they are dead. For they have overlooked no point that has a bearing upon laws, customs, or political science; in fact, they seem to have devoted their retirement to the benefit of us who are engaged in public business. The principal thing done, therefore, by those very devotees of the pursuits of learning and science is to apply their own practical wisdom and insight to the service of humanity. And for that reason also much speaking (if only it contain wisdom) is better than speculation never so profound without speech; for mere speculation is self-centred, while speech extends its benefits to those with whom we are united by the bonds of society.
