the logical handcuff: accept the premises and you're forced to drag the conclusion along.
means The relationship by which one statement logically follows from, and is necessitated by, another — if the first is true, the second must be too.
from From Old French 'entaillier,' to cut into or carve (en- 'in' + 'taillier' 'to cut,' source also of 'tailor' and 'detail'). It first meant to limit how an estate could be inherited — to 'cut' the line of succession so property passed in a fixed, unbreakable order. That sense of a binding, predetermined chain was later borrowed by logicians for the way a conclusion is locked to its premises.
