Bergson, Time and Free Will

(Essai sur les données immédiates de la conscience)


Chapter I, "The Intensity of Psychic States"

Part XIII: "Sensation of Light"


§36 "Photometric Experiments. We Perceive Different Shades and afterwards Interpret Them as Decreasing Intensities of White Light"


Imagine four candles illuminating a sheet of paper. We blow out the candles one by one. The paper seems to become less intensely lit. It is more accurate to say that a layer of shadow passes over the paper when we blow out a candle. This shadow is no less real than the light. It makes the paper a different shade of white. So it does not cause us to have less of a sensation. (53b.d) "Black has just as much reality for our consciousness as white." (54a) The varying shades of white are like colors of a spectrum. Each are different, but none are greater or lesser than another.


Colors can be lightened and darkened. Regardless of any modification to a color, we only perceive it as qualitatively different, even though we often mistakenly think it is quantitatively different. (54c.d)
