Light or No Light, that is the question...
Light or No Light, that is the question...
Light - technically or scientifically speaking - is nothing else but an electromagnetic radiation of a certain frequency (with some discussion about the wave/particle dualism of its nature) .
Visible light occupies but a very small frequency spectrum (wavelength: ~ 380 - 780 nm) out of this broad range of electromagnetic radiation which goes from the highly energetic gamma waves (wavelength: ~3x10-16m) to the low energy radio-waves (wavelength: ~ 3 km) with many other ranges in between which serve several purposes for us modern humans (TV, microwave, radio, radar, etc., etc.).
This electromagnetic radiation is always there in our universe as it is emitted by many sources (stellar bodies), and thus "light" exists independently of whether it is "perceived" or not. But what does the trick for us seeing species, is that the small range of frequency we can "see" is the very range which is only to a small degree absorbed by water and thus evolution has developed a sensorium for this frequency range which has helped early species to survive in the surface regions of water.
Since what we call light is only a very very small and - seemingly - very arbitrarily chosen range of electromagnetic radiation the conclusion is near, that "light" for us humans is also a philosophical concept. Would we not be able to perceive it with our sensorium or use it some other way (like microwave, TV), it would - just like many other parts of the electromagnetic spectrum have no significance for us and never got specifically "named". The concept of "light" and "darkness" as a pair of dependent opposites - just like "good" and "evil" - would have never arisen (aside from the question whether we as humans would exist had the early species not developed a sensorium to perceive light).
Consequently we could say "Without sight there would be no light and dark" even though the radiation that now represents light for us would still exist independently.
But Tolkien has now, it seems, ascribed a certain spiritual quality to "light" and thus made the connection between light=good and dark=evil (but of course he was neither the first nor the only one who did this). Verlyn Flieger, in her book Splintered Light pays a lot of attention to this connection and argues that light in Tolkiens mythology ever diminishes and splinters as time goes on and that this diminishing and splintering is somehow parallelled by the development of language and the spiritual development of the Children of Ilúvatar, mostly in the firstborn...
