The Society that separates its scholars from its warriors will have its thinking done by cowards and its fighting done by fools. - Thucydides

war is a matter not so much of arms as of money,

There is, however, no advantage in reflections on the past further than may be of service to the present. For the future we must provide by maintaining what the present gives us and redoubling our efforts; it is hereditary to us to win virtue as the fruit of labour, and you must not change the habit, even though you should have a slight advantage in wealth and resources; for it is not right that what was won in want should be lost in plenty.

And do not imagine that what we are fighting for is simply the question of freedom or slavery: there is also involved the loss of our empire and the dangers arising from the hatred which we have incurred in administering it. Nor is it any longer possible for you to give up this empire, though there may be some people who in a mood of sudden panic and in a spirit of political apathy actually think that this would be a fine and noble thing to do. Your empire is now like a tyranny: it may have been wrong to take it; it is certainly dangerous to let it go.
