Categories: Comparisons

An analogy used by a scientist:

"Just as we do not need to distinguish, in principle, between the current in a water pipe and the flow of blood in the vessels, no more should we expect, beforehand, any profound fundamental difference between the propagation of sense impressions in the nerves and conduction of electricity in a metal wire."
