They never applied their minds to any kind of learning, further than what was necessary for use and service ; nature indeed having made them more fit for the purposes of war than for the improvements of knowledge. And therefore for speculative sciences and philosophic studies, they looked upon them as foreign to their business and unserviceable to their ends of living, and for this reason they would not tolerate them amongst them, nor suffer the professors of them to live within their government. They banished them their cities, as they did all sorts of strangers, esteeming them as things that did debase the true worth and excellency of virtue, which they made to consist only in manly actions and generous exercises, and not in vain disputations and empty notions. So that the whole of what their youth was instructed in was to learn obedience to the laws and injunctions of their governors, to endure with patience the greatest labors, and where they could not conquer, to die valiantly in the field For this reason likewise itwas, that all mechanic arts and trades, all vain and insignificant employments, such as regarded only curiosity or pleasure, were strictly prohibited them, as things that would make them degenerate into idleness and covetousness, would render them vain and effeminate, useless to themselves, and unserviceable to the state ; and on this account it was that they would never suffer any scenes or interludes, whether of comedy or tragedy, to be set up among them, lest there should be any encouragement given to speak or act any thing that might savor of contempt or contumely against their laws and government, it being customary for the stage to assume an indecent liberty of taxing the one with faults and the other with imperfections.
