“We can judge our progress by the courage of our questions and the dept...” — Carl Sagan Quote

“We can judge our progress by the courage of our questions and the depth of our answers, our willingness to embrace what is true rather than what feels good.”

“You probably don't need more weapons than what's required to destroy every city on earth. There's only 2,300 cities. So, the United States, by that criteria, only needs 2,300 nuclear weapons - well, we've got more than 25,000!”

“Whatever their neurological and molecular antecedents, hallucinations feel real. They are sought out in many cultures and considered a sign of spiritual enlightenment.”

“When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.”

“If you wish to make an apple pie from scratch, you must first invent the universe.”

“The Cosmos is all that is or ever was or ever will be. Our feeblest contemplations of the Cosmos stir us - there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.”

“We know evolution happened because innumerable bits of data from myriad fields of science conjoin to paint a rich portrait of life's pilgrimage.”

“We all have an unscientific weakness for being always in the right, and this weakness seems to be particularly common among professional and amateur politicians. But the only way to apply something like scientific method in politics is to proceed on the assumption that there can be no political move which has no drawbacks, no undesirable consequences. To look out for these mistakes, to find them, to bring them into the open, to analyse them, and to learn from them, this is what a scientific politician as well as a political scientist must do. Scientific method in politics means that the great art of convincing ourselves that we have not made any mistakes, of ignoring them, of hiding them, and of blaming others from them, is replaced by the greater art of accepting the responsibility for them, of trying to learn from them, and of applying this knowledge so that we may avoid them in future.”

“Dream research is a wonderful field. All you do is sleep for a living.”

“The unraveling of our home planet is a mental disorder in which thoughs and feelings are so impaired they have no relationship to external reality. Wild is the opposite. It is when our thoughts, feelings, and actions are exquisitely sensity to our relationship with the living world and each other.”
