The Thoughts Of Locke In Systemic Functional Linguistics [2]

Russell (1961: 587):

Reason, as Locke uses the term, consists of two parts: first an inquiry as to what things we know with certainty; second, an investigation of propositions which it is wise to accept in practice, although they have only probability and not certainty in the favour.  'The grounds of probability,' he says, 'are two: conformity with our own experience, or the testimony of others' experience.'

In Systemic Functional Linguistics, certainty and probability are values of modalisation, an interpersonal system that grades propositions between positive and negative polarity.

For Locke's 'experience', read 'construals of experience as meaning' in Systemic Functional Linguistics.
