“States have two kinds of power: latent power and military power.”

Power and the Useful Economist (1973)
Context: When the modern corporation acquires power over markets, power in the community, power over the state and power over belief, it is a political instrument, different in degree but not in kind from the state itself. To hold otherwise — to deny the political character of the modern corporation — is not merely to avoid the reality. It is to disguise the reality. The victims of that disguise are those we instruct in error. The beneficiaries are the institutions whose power we so disguise. Let there be no question: economics, so long as it is thus taught, becomes, however unconsciously, a part of the arrangement by which the citizen or student is kept from seeing how he or she is, or will be, governed.

Context: Faculty X is simply that latent power in human beings possess to reach beyond the present. After all, we know perfectly well that the past is as real as the present, and that New York and Singapore and Lhasa and Stepney Green are all as real as the place I happen to be in at the moment. Yet my senses do not agree. They assure me that this place, here and now, is far more real than any other place or any other time. Only in certain moments of great inner intensity do I know this to be a lie. Faculty X is a sense of reality, the reality of other places and other times, and it is the possession of it — fragmentary and uncertain though it is — that distinguishes man from all other animals.
