Light (1)

The study of light entails the largest and the smallest, relativity and quantum mechanics. It also allies to the three zones of biological, psychological and social optics, if we are to migrate from the physics to the chemistry, biochemistry, physiology and psychology of light – a series that suggests a leg-up at each phase, culminating in the tricky premise that psychology is only explicable at the level of the social. It remains to construe the declination of social psychology and the material form in which it occurs: mediation.
