  Linguistic beliefs of the second category, i.e. those that also include logical terms such as ‘not’, ‘and’ and ‘or’ are more complex. In analyzing them, Ramsey heavily relies on the Tractarian view of logical constants. Ramsey, like Wittgenstein, thinks that logical words are not names, i.e. they do not represent. The meanings of ‘not’ and ‘or’ are determined by the agents’ attitudes towards the sentences that include them. Believing that not-p and disbelieving that p are ‘equivalent occurrences’ (1927a, [PP] 43), i.e.  they express the same attitude because their practical effects are indistinguishable (1927a, [PP] 44; Dokic and Engel 2002, 24).
