“We can fortell little of the future save that the thing that has not been is the thing that shall be.”
― J.B.S. Haldane, Daedalus

“To light a lamp as a source of light is about as wasteful of energy as to burn down ones house to roast one's pork.”
― J.B.S. Haldane

“The conservative has but little to fear from the man whose reason is the servant of his passions, but let him beware of him in whom reason has become the greatest and most terrible of the passions. These are the wreckers of outworn empires and civilisations, doubters, disintegrators, deicides.”
― J.B.S. Haldane

“There is not a single effect in Nature, not even the least that exists, such that the most ingenious theorists can ever arrive at a complete understanding of it. This vain presumption of understanding everything can have no other basis than never understanding anything. For anyone who had experienced just once the perfect understanding of one single thing, and had truly tasted how knowledge is attained, would recognise that of the infinity of other truths he understands nothing.”
― Galileo Galilei, Dialogue Concerning the Two Chief World Systems: Ptolemaic and Copernican
