Daniel Dennet on the Illusion of Uncaused Acts

Elbow Room: The Varieties of Free Will Worth Wanting (MIT Press: 1984), p. 77.

Whatever else we are, we are information-processing systems, and all information-processing systems rely on amplifiers of a sort. Relatively small causes are made to yield relatively large effects. … Vast amounts of information arrive on the coattails of negligible amounts of energy, and then, thanks to the amplification powers of systems of switches, the information begins to do some work — evoking other information that was stored long ago, for instance transmuting it for the present occasion in a million small ways, and leading eventually to an action whose pedigree of efficient (or triggering) causation is so hopelessly inscrutable as to be invisible. We see the dramatic effects leaving; we don’t see the causes entering; we are tempted by the hypothesis that there are no causes.
