So yes, lets focus on one of the dualistic approaches, or the more important ones, instead of being so general as to compare them so easily and lump them together. The true nature of light, as in EM radiation, and dark, is hardly a good comparison, but if you mean the concept of light and dark, as in good and evil, well then we are just speaking about good and evil, which I believe is one of the most important concepts to human and humanity. If you know of another very important dual concept, please state it and we can discuss it. Positive and negative, again, if not speaking about magnetic, this is related to good and evil, so lets just stick to one, unless you have other separate ones.

Is creating individuality the highest purpose? Obviously in a sense, for the individual, the nature of being, is solely dependent on the very tautological concept of an individual manning its way through its being through the realm it finds itself thrust into being, in. But, this says nothing about the potential value systems and powers regarding the creating of the realm, the shaping of the realm, the shaping of the individual, the shaping of individuals, for better and for worse, and why.
