Quote

Maimonides·1190

Every Israelite has a duty to study whether he is poor or rich, whether healthy or suffering, whether young or very old and in failing strength, even if he is poor and supported by charity or begs from door to door.

Aesop

Better be wise by the misfortunes of others than by your own.

Isaac Newton·1704

To explain all nature is too difficult a task for any one man or even for any one age. 'Tis much better to do a little with certainty, & leave the rest for others that come after you, than to explain all things by conjecture without making sure of any thing.
