Kindness is the language which the deaf can hear and the blind can see.
Education is the kindling of a flame, not the filling of a vessel.
Never memorize something that you can look up.
Ask the right questions, and nature will open the doors to her secrets.
Every cause produces more than one effect.
That which can be asserted without evidence, can be dismissed without evidence.
Education consists mainly of what we have unlearned.
I think that we must find some way to get more common sense, more rationality, in our decisions and less emotion.
Refusal to believe until proof is given is a rational position; denial of all outside of our own limited experience is absurd.
