Fear is not conditioned; security is unlearned, in the presence of particular things or contexts, as a consequence of violation of explicit or implicit presupposition. Classical behavioral psychology is wrong in the same manner our folk presumptions are wrong: fear is not secondary, not learned; security is secondary, learned. Everything not explored is tainted, a priori, with apprehension. Any thing or situation that undermines the foundations of the familiar and secure is therefore to be feared.
