The principle that rationality operates within paradigms—that what counts as rational is framework-dependent, that standards of rationality shift over time and vary across contexts. The Law of Rational Paradigms argues that there is no transhistorical, transcultural standard of rationality; there are only rational paradigms, each adequate to its context, each limited by its assumptions. Scientific rationality is one paradigm; legal rationality is another; everyday rationality is another. None is rationality itself; all are rationalities, each valid within its domain. The law doesn't say reason is arbitrary; it says reason is plural, and that the task is to understand different rational paradigms.
Example: "She'd thought rationality was the same for everyone, everywhere. The Law of Rational Paradigms showed her otherwise: what was rational in court wasn't rational in lab; what was rational in one culture wasn't rational in another. Rationality wasn't one thing; it was many, each valid in its context. She stopped looking for universal reason and started learning local rationalities."
