Finally, note a peculiar implication of an ordinary-language analysis of trust. Anyone who wishes to make trust a simple primitive or who wishes to take it as a deontological moral concept should have trouble with real-world experience, which often lacks any such notion. (A deontological concept is universally applicable and derivable from pure reason.) Even today, many languages have no direct, perspicuous equivalent of the term.

DEFINE: Clarifies what a deontological concept is: universally applicable and derivable from pure reason.
