 In addition to providing these quick theories of ‘reverie’, ‘attention’ and ‘intention or study’, the very same sentence of Locke’s Essay provides theories of ‘remembrance’, ‘recollection’, ‘contemplation’, ‘sleep’, ‘dreaming’, and ‘ecstasy’. It is significant that Locke’s account of attention is given so briefly, and that it goes by as part of a crowd of theories of these various other mental phenomena. Locke is not here engaging in an uncharacteristically slapdash piece of rapid-fire theorizing. His intention in going through this catalogue is to establish that these are topics for which no new substantive theory is needed. These are, in Locke’s theory, simply ‘modes of thinking’: ‘reverie’, ‘study’ etc. are not names for independent phenomena, existing in their own right. Instead they are the various names that thinking is given when it takes place in various ways.
