“The interest of [businessmen] is always in some respects different from, and even opposite to, that of the public ... The proposal of any new law or regulation of commerce which comes from this order ... ought never to be adopted, till after having been long and carefully examined ... with the most suspicious attention. It comes from an order of men ... who have generally an interest to deceive and even oppress the public”
― Adam Smith, An inquiry into the nature and causes of the wealth of nations. Volume 1 of 2

“Trees are made of air, primarily. When they are burned, they go back to air, and in the flaming heat is released the flaming heat of the Sun which was bound in to convert the air into tree. And in the ash is the small remnant of the part which did not come from air, that came from the solid earth, instead.”
― Richard P. Feynman

“Never argue with an idiot. They will only bring you down to their level and beat you with experience.”
