How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to opposition is resistance.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Logic

the classical scheme of logical relations, such as contradictory and contrary, among the four basic categorical statements.

The square of opposition is the classical scheme of logical relations among the four basic categorical statements (all S are P, no S are P, some S are P, some S are not P), setting out which pairs are contradictory, contrary, subcontrary, or ordered as subaltern. Aristotle laid out these relations in De Interpretatione (ca. 350 B.C.E.) and the Prior Analytics, and later writers such as Apuleius and Boethius arranged them into the familiar diagram; Terence Parsons's account The Traditional Square of Opposition (2017) reconstructs the scheme and its assumptions for modern readers. Here opposition names a fixed relationship between propositions, such as two claims that cannot both be true, and it has nothing to do with a planet placed across the sky from the Sun or with parties out of government.[1][2][3]

Unit
A named logical relation between two categorical propositions
Recovery means
Not applicable
Measured by
Determined by the truth conditions of the propositions and the inference rules that connect them

Political science

the legislative parties or members not in government whose recognized role is to scrutinize, criticize, and offer an alternative.

The (parliamentary) opposition is the set of parties or members in a legislature who are not in government and whose recognized role is to scrutinize, criticize, and offer an alternative to those in power. The practice of a loyal opposition took shape in the British Parliament in the early nineteenth century, and Robert A. Dahl's edited study Political Oppositions in Western Democracies (1966) established the comparative study of how oppositions are organized and tolerated across democracies. Here opposition names an institutional role within a system of government, counted by seats and defined by its relation to the governing majority, and it shares nothing with a planet across the sky from the Sun or a relation between logical propositions.[4]

Unit
The bloc of legislators outside the governing majority
Recovery means
Not applicable
Measured by
Identified by party membership and seat counts, and by formal recognition such as shadow offices or opposition status
