Included as a quotation in The Great Quotations (1977) by George Seldes, p. 35, this appears to be a paraphrase of a summation of arguments of Bruno's speech in a debate at the College of Cambray (25 May 1588) which are not clearly presented as a direct translation of his statements:
: In an inspired speech Bruno, through the interpreter, Jean Hennequin, of Paris, declared the discovery of numberless worlds in the One Infinite Universe. Nothing was more deplorable, declared he, than the habit of blind belief, for of all other things it hinders the mind from recognizing such matters as are in themselves clear and open. It was proof of a base and low mind for one to wish to think with the masses or majority, merely because the majority is the majority. Truth does not change because it is, or is not, believed by a majority of the people. However, he cautioned that they should not be influenced by the fervor of speech, but by the weight of his argument and the majesty of truth.

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?"
