Two Ancient Greek Quotations

These quotations decorate the doors of other teachers I know...

"Most ideas about teaching are not new, but not everyone knows the old ideas."
-Euclid, ~300 B.C.E.

"The budget should be balanced, the treasury should be refilled, public debt should be reduced, the arrogance of officialdom should be tempered and controlled, and the assistance to foreign lands should be curtailed lest Rome become bankrupt. People must again learn to work, instead of living on public assistance."
-Cicero, 55 B.C.E.
