Err Quotes
For the fact is thatneither the grammarian nor any other person of skill ever makes a mistakein so far as he is what his name implies; they none of them err unlesstheir skill fails them, and then they cease to be skilled artists. Noartist or sage or ruler errs at the time when he is what his name implies; though he is commonly said to err.
Plato
All our knowledge hast its origins in our perceptions? In nature there is no effect without a cause? Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments? Science is the observation of things possible, whether present or past; prescience is the knowledge of things which may come to pass.
Leonardo da Vinci
One will seem to promote virtue better by using encouragement and persuasion of speech than law and necessity. For it is likely that he who is held back from wrongdoing by law will err in secret but that he who is urged to what he should by persuasion will do nothing wrong either in secret or openly. Therefore he who acts rightly from understanding and knowledge proves to be at the same time courageous and right-minded.
Democritus
