“Virtue's a mere name,
Or 'tis high venture that achieves high aim.”

The Mill on the Floss (1860)

The Dominant Idea (1910)
Context: It is not to be supposed that any one will attain to the full realization of what he purposes, even when those purposes do not involve united action with others; he will fall short; he will in some measure be overcome by contending or inert opposition. But something he will attain, if he continues to aim high.
What, then, would I have? you ask. I would have men invest themselves with the dignity of an aim higher than the chase for wealth; choose a thing to do in life outside of the making of things, and keep it in mind, — not for a day, nor a year, but for a life-time. And then keep faith with themselves! Not be a light-o'-love, to-day professing this and to-morrow that, and easily reading oneself out of both whenever it becomes convenient; not advocating a thing to-day and to-morrow kissing its enemies' sleeve, with that weak, coward cry in the mouth, "Circumstances make me." Take a good look into yourself, and if you love Things and the power and the plenitude of Things better than you love your own dignity, human dignity, Oh, say so, say so! Say it to yourself, and abide by it. But do not blow hot and cold in one breath. Do not try to be a social reformer and a respected possessor of Things at the same time. Do not preach the straight and narrow way while going joyously upon the wide one. Preach the wide one, or do not preach at all; but do not fool yourself by saying you would like to help usher in a free society, but you cannot sacrifice an armchair for it.

Difficile est, fateor, sed tendit in ardua virtus
et talis meriti gratia maior erit.

Context: These are the elements of the plan I am proposing. Real reform starts by giving schools and school districts more authority and flexibility. We cannot expect schools to change unless they have the freedom to change. My plan respects the principle of local control. It does not try to run the schools from a central office in Washington. I view principals, teachers and parents as allies in reform. They are ready to raise the standards, ready to take responsibility and answer for results. Those results must be measured by testing every child every year, in tests developed and administered by states and local districts, not the federal government. Without yearly testing, we do not know who is falling behind and who needs our help. Without yearly testing, too often we don't find failure until it is too late. Testing allows us to help children early, before frustration turns into apathy. We need to aim high, but we also need to be realistic. Many schools, particularly those in poor neighborhoods, will need help to meet high standards. And they will have it, including a new $5 billion initiative over five years for reading instruction. The goal is to improve our public schools. We want them to succeed, and when they're willing to change, we'll give them the tools to do so.

Variant: Cynics are - beneath it all - only idealists with awkwardly high standards.
