„The majority of them seem to be "sub-critical," i.e., to correspond in this analogy to piles of sub-critical size. An idea presented to such a mind will on average give rise to less than one idea in reply. A smallish proportion are super-critical. An idea presented to such a mind may give rise to a whole "theory" consisting of secondary, tertiary and more remote ideas.“
— Alan Turing, Context: Another simile would be an atomic pile of less than critical size: an injected idea is to correspond to a neutron entering the pile from without. Each such neutron will cause a certain disturbance which eventually dies away. If, however, the size of the pile is sufficiently increased, the disturbance caused by such an incoming neutron will very likely go on and on increasing until the whole pile is destroyed. Is there a corresponding phenomenon for minds, and is there one for machines? There does seem to be one for the human mind. The majority of them seem to be "sub-critical," i. e., to correspond in this analogy to piles of sub-critical size. An idea presented to such a mind will on average give rise to less than one idea in reply. A smallish proportion are super-critical. An idea presented to such a mind may give rise to a whole "theory" consisting of secondary, tertiary and more remote ideas. Animals minds seem to be very definitely sub-critical. Adhering to this analogy we ask, "Can a machine be made to be super-critical?" p. 454.

Response to a reporter seeking an interview during a vacation with her husband in Brittany, who mistaking her for a housekeeper, asked her if there was anything confidential she could recount, as quoted in Living Adventures in Science (1972), by Henry Thomas and Dana Lee Thomas <!-- Pierre died in 1906, so this comment dates to before that time, possibly to a trip in 1897 --> Variant: In science, we must be interested in things, not in persons. This is stated to be a declaration she often made to reporters, in Madame Curie : A Biography (1937) by Eve Curie Labouisse, as translated by Vincent Sheean, p. 222

„God has not given to us (in this state of existence) more than very limited powers of expression of one's ideas and feelings“

Context: Circumstances have been such, that I have lived almost entirely secluded for some time. Those who are much in earnest and with single minds devoted to any great object in life, must find this occasionally inevitable.... You will wonder at having heard nothing from me; but you have experience and candour enough to perceive and know that God has not given to us (in this state of existence) more than very limited powers of expression of one's ideas and feelings... I shall be very desirous of again seeing you. You know what that means from me, and that it is no form, but the simple expression and result of the respect and attraction I feel for a mind that ventures to read direct in God's own book, and not merely thro' man's translation of that same vast and mighty work. In a letter to Andrew Crosse, as quoted in Eugen Kölbing's Englische Studien, Volume 19 https://archive.org/stream/englischestudien19leipuoft#page/157/mode/1up (1894), Leipzig; O.R. Reisland, "Byron's Daughter", p. 157.

Context: If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, the wish to belittle them. It springs rather from my conviction that, if our civilization is to survive, we must break with the habit of deference to great men. Great men may make great mistakes; and as the book tries to show, some of the greatest leaders of the past supported the perennial attack on freedom and reason. Their influence, too rarely challenged, continues to mislead those on whose defence civilization depends, and to divide them. The responsibility of this tragic and possibly fatal division becomes ours if we hesitate to be outspoken in our criticism of what admittedly is a part of our intellectual heritage. By reluctance to criticize some of it, we may help to destroy it all. Preface to the First Edition
