“Nothing is so fatal to the progress of the human mind as to suppose that our views of science are ultimate; that there are no mysteries in nature; that our triumphs are complete, and that there are no new worlds to conquer.”
As quoted in Humphry Davy : Science & Power (1998) by David Knight, p. 87

Emperor Has No Clothes Award acceptance speech (2003)
Context: The purpose of science in understanding who we are as humans is not to rob us of our sense of mystery, not to cure us of our sense of mystery. The purpose of science is to constantly reinvent and reinvigorate that mystery. To always use it in a context where we are helping people in trying to resist the forces of ideology that we are all familiar with.

Kosmos (1845 - 1847)
Context: From the remotest nebulæ and from the revolving double stars, we have descended to the minutest organisms of animal creation, whether manifested in the depths of ocean or on the surface of our globe, and to the delicate vegetable germs which clothe the naked declivity of the ice-crowned mountain summit; and here we have been able to arrange these phenomena according to partially known laws; but other laws of a more mysterious nature rule the higher spheres of the organic world, in which is comprised the human species in all its varied conformation, its creative intellectual power, and the languages to which it has given existence. A physical delineation of nature terminates at the point where the sphere of intellect begins, and a new world of mind is opened to our view. It marks the limit, but does not pass it.
“Our leaders invent nothing but new taxes, and conquer nothing but the pockets of their subjects.”

Variants:
Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.
Science cannot solve the ultimate mystery of nature, for in the final analysis we ourselves are part of the mystery we are trying to solve.

Commenting upon the Aleinu prayer, in "Why We Remain Jews" (1962)
Context: The kingdom is Yours, and You will reign in glory for all eternity. As it is written in Your Torah: "The Lord shall reign for ever and ever." And it is said: " And the Lord shall be King over all the earth: on that day the Lord shall be One, and His name One."
No nobler dream was ever dreamt. It is surely nobler to be a victim of the most noble dream than to profit from a sordid reality and to wallow in it. Dream is akin to aspiration. And aspiration is a kind of divination of an enigmatic vision. And an enigmatic vision in the emphatic sense is the perception of the ultimate mystery, of the truth of the ultimate mystery. The truth of the ultimate mystery — the truth that there is an ultimate mystery, that being is radically mysterious — cannot be denied even by the unbelieving Jew of our age. That unbelieving Jew of our age, if he has any education, is ordinarily a positivist, a believer in Science, if not a positivist without any education.
