Bacon's idea of a natural philosopher thus resembles the professional actor in Evelyn Tribble's reconstruction, whose "memory, vigilancy, and pregnancy of wit" afford him "a quality of alertness and attentiveness" and a "flexible mindfulness that comes only from long practice and experience." (24) To the "learned" or "literate" mind--whether it belongs to an actor, a Lord of Misrule, a charismatic courtier, or a natural philosopher--unexpected outcomes could become prompts for subsequent experiments rather than the breaking point of prior endeavors.
When confronted with the potentially formless chaos of revelry, then, "memory, vigilancy, and pregnancy of wit" were often one's only resources.
Player hath many times, many excellent qualities: as dancing, actiuitie, musicke, song, elloqution, abilitie of body, memory, vigilancy
, skill of weapon, pregnancy of wit, and such like: in all which hee resembleth an excellent spring of water, which growes the more sweeter, and the more plentifull by the often drawing out of it: so are all these the more perfect and plausible by the often practice.
