… is from page 148 of F.A. Hayek’s profound 1952 book The Counter-Revolution of Science, as this book appears as part of volume 13 (Studies on the Abuse & Decline of Reason, Bruce Caldwell, ed. [2010]) of the Collected Works of F.A. Hayek:
Even more significant of the inherent weakness of the collectivist theories is the extraordinary paradox that from the assertion that society is in some sense more than merely the aggregate of all individuals their adherents regularly pass by a sort of intellectual somersault to the thesis that in order that the coherence of the larger entity be safeguarded it must be subjected to conscious control, that is, to the control of what in the last resort must be an individual mind. It thus comes about that in practice it is regularly the theoretical collectivist who extols individual reason and demands that all forces of society be made subject to the direction of a single mastermind, while it is the individualist who recognises the limitations of the powers of individual reason and consequently advocates freedom as a means for the fullest development of the powers of the inter-individual process.
