Courage is never to let your actions be influenced by your fears.

The progress of science is strewn, like an ancient desert trail, with the bleached skeleton of discarded theories which once seemed to possess eternal life.
Interpretation
What this quote means
Scientific progress often involves the rejection of theories that were once widely accepted.
In this quote, Arthur Koestler reflects on the nature of scientific advancement, suggesting that the path to knowledge is often littered with the remnants of outdated theories. These theories, which once appeared to be true and foundational, are eventually dismissed as new evidence and understanding emerge, highlighting the ever-evolving nature of science and our quest for truth.

If one looks with a cold eye at the mess man has made of his history, it is difficult to avoid the conclusion that he has been afflicted by some built-in mental disorder which drives him towards self-destruction. Murder within the species on an individual or collective scale is a phenomenon unknown in the whole animal kingdom, except for man, and a few varieties of ants and rats.

Space-ships and time machines are no escape from the human condition. Let Othello subject Desdemona to a lie-detector test; his jealousy will still blind him to the evidence. Let Oedipus triumph over gravity; he won't triumph over his fate.

The real achievement in discoveries... is seeing an analogy where no one saw one before... The essence of discovery is that unlikely marriage of cabbages and kings β of previously unrelated frames of reference or universes of discourse β whose union will solve the previously insoluble problem.

In my youth I regarded the universe as an open book, printed in the language of equations, whereas now it appears to me as a text written in invisible ink, of which in our rare moments of grace we are able to decipher a small segment.

The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species.

I think we're just scratching the surface. One of the most exciting aspects of 23andMe is that we're enabling you to watch a revolution unfold live during your lifetime, and I think that the decoding of the genome, in my opinion, is the most fascinating discovery of our lifetime, and you get to be part of it.

The scientific value of truth is not, however, ultimate or absolute. It rests partly on practical, partly on aesthetic interests. As our ideas are gradually brought into conformity with the facts by the painful process of selection,-for intuition runs equally into truth and into error, and can settle nothing if not controlled by experience,-we gain vastly in our command over our environment. This is the fundamental value of natural science
