“Although science claims the whole universe as its field... it confesses that its ignorance is more widely extended than its knowledge. In this very confession... it finds a safeguard for future progress. Science cannot... allow theologian or metaphysician... to the foreshore of our present ignorance, and so hinder the development in due time...”

“Science can destroy religion by ignoring it as well as by disproving its tenets.”
1950s

Context: Science can destroy religion by ignoring it as well as by disproving its tenets. No one ever demonstrated, so far as I am aware, the non-existence of Zeus or Thor — but they have few followers now.

“A nation which is ignorant of its history cannot properly make choices about its future.”
St Andrew's Day (November 30, 2007)

This "aphorism" was expressed in different forms by Josh Billings and Socrates. note: Often misquoted as, "The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge," and often misattributed to Stephen Hawking.

Context: One cannot ignore half of life for the purposes of science, and then claim that the results of science give a full and adequate picture of the meaning of life. All discussions of 'life' which begin with a description of man's place on a speck of matter in space, in an endless evolutionary scale, are bound to be half-measures, because they leave out most of the experiences which are important to use as human beings.

"Why We Need To Understand Science" in The Skeptical Inquirer Vol. 14, Issue 3 (Spring 1990)
Context: Science is much more than a body of knowledge. It is a way of thinking. This is central to its success. Science invites us to let the facts in, even when they don’t conform to our preconceptions. It counsels us to carry alternative hypotheses in our heads and see which ones best match the facts. It urges on us a fine balance between no-holds-barred openness to new ideas, however heretical, and the most rigorous skeptical scrutiny of everything — new ideas and established wisdom. We need wide appreciation of this kind of thinking. It works. It’s an essential tool for a democracy in an age of change. Our task is not just to train more scientists but also to deepen public understanding of science.
