What's the difference between stipulation and postulation?
I am a German native speaker and both words can be translated to the German 'Forderung'.
In what context can 'postulation' be used? Is it an antiquated word?
According to Websters, stipulate means to make an agreement or to demand an express term in an agreement. There's the sense that two or more minds are at work to agree on a specific term or set of terms.
Postulate, says Wesbters, is "to assume or claim as true, existent, or necessary." There's no sense of two minds coming to agreement and memorializing it.
Postulate isn't antiquated, but usually used in the context of setting or assuming terms in an argument or proposition.
