I could trust a fact and always cross-question an assertion
Things do not change; we change
When people talk, listen completely. Most people never listen
One must be sane to think clearly, but one can think deeply and be quite insane
Nothing strengthens authority so much as silence
The brave may not live forever – But the cautious do not live at all
