Bacon notes that in Genesis, light is created before any of the material things it will later illuminate — sun, plants, animals, man. He reads this ordering as symbolically exact: light stands to the physical world as knowledge stands to the mind, the precondition that makes everything else visible and intelligible rather than one item among others.
Bacon reinforces the point by noting that of all the days of creation, only the seventh — the day of rest and contemplation rather than making — is blessed. For a philosopher whose reputation rests on demanding useful, active knowledge, it is a telling concession: contemplation itself, not only its fruits, carries a dignity that Bacon traces to the very structure of Genesis.
