“The measure of greatness in a scientific idea is the extent to which it stimulates thought and opens up new lines of research.”

“New scientific ideas never spring from a communal body, however organized, but rather from the head of an individually inspired researcher who struggles with his problems in lonely thought and unites all his thought on one single point which is his whole world for the moment.”

“One cannot, therefore, understand Arabic science without considering the extent to which Islam influenced scientific and philosophical thought. Arabic science was, throughout its golden age, inextricably linked to religion. Clearly, the scientific revolution of the Abbasids would not have taken place if it were not for Islam, incontrast to the spread of Christianity over the preceding centuries, which had nothink like the same effect in stimulation and encouraging original scientific thinking.”

“Any great art work … revives and readapts time and space, and the measure of its success is the extent to which it makes you an inhabitant of that world - the extent to which it invites you in and lets you breathe its strange, special air.”

“I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.”

“What is called for is an exquisite balance between two conflicting needs: the most skeptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas. If you are only skeptical, then no new ideas make it through to you. On the other hand, if you are open to the point of gullibility and have not an ounce of skeptical sense in you, then you cannot distinguish useful ideas from the worthless ones.”
