Common
sense in philosophy has a complex status. For Reid and the Scottish Common Sense school, common sense refers to a set of basic, self-evident beliefs (that the external world exists, that other people have minds) that are properly basic — they require no
justification and serve as
the foundation for all other inquiry. Moore's defence of common sense against
idealist philosophy drew on this tradition. Gramsci's analysis of common sense as a form of ideological consciousness — containing both practical wisdom and mystification — provides a critical alternative, arguing that common sense is always the common sense of a particular class and historical moment. Wittgenstein's later philosophy treats common sense as an
expression of shared forms of life. For poets, common sense is both a resource (the poem that speaks from and to shared experience) and a target (the poem that defamiliarizes the taken-for-granted). Related terms: Reid, Moore, Gramsci's ideology, doxa, forms of life, defamiliarization.
