The "inward" wits[edit]
Stephen Hawes' poem Graunde Amoure shows that the five (inward) wits were "common wit", "imagination", "fantasy", "estimation", and "memory".[3] "Common wit" corresponds to Aristotle's concept of common sense (sensus communis), and "estimation" roughly corresponds to the modern notion of instinct.[8]
Shakespeare himself refers to these wits several times, in Romeo and Juliet (Act I, scene 4, and Act II, scene iv), King Lear (Act III, scene iv), Much Ado About Nothing (Act I, scene i, 55), and Twelfth Night (Act IV, scene ii, 92).[3] He distinguished between the five wits and the five senses, as can be seen from Sonnet 141.[3][9][10]
The five wits are derived from the faculties of the soul that Aristotle describes in De Anima.[10]
The inward wits are part of medieval psychological thought. Geoffrey Chaucer translated Boethius' Consolation of Philosophy into Middle English. According to Chaucer's translation, "ymaginacioun" is the most basic internal faculty of perception. One can, with the imagination, call to mind the image of an object, either one directly experienced or a purely imaginary fabrication. Above that comes "resoun", by which such images of individual objects are related to the universal classes to which they belong. Above that comes "intelligence", which relates the universal classes to eternal "symple forme" (akin to a Platonic ideal). Humans are thus "sensible", "ymaginable", and "reasonable" (i.e. capable of sensing, imagination, and reason, as defined), all three of which feed into memory. (Intelligence is the sole remit of Divine Providence.)[11]
To that quartet is also added "phantasia", a creative facet of imagination. A famous example of this is given by Augustine, who distinguishes between imagining Carthage, from memory (since he had been there), and imagining Alexandria, a pure fantasy image of a place that he had never been to.[12]
