define "natural" as something that is considered normal within a particular context. Lets inspect the act of breast feeding. Most would say that breast feeding for a new born infant is essential in its development, as the mother is able to pass onto her offspring necessary aliments crucial for its survival. We would then conclude that breast feeding were "natural"; would we then also have to deduce that bottle feeding were unnatural and wrong? What if the mother were unable to breast feed her child? Would we say that the mother was in an unnatural state, that she was acting unnaturally by allowing her child to feed from a bottle? And so we can say that, in this case, breast feeding is natural, in a particular context. We are able to see that in certain circumstances, one would be unable to conduct oneself in what would be called a "natural" way; that is, we would be acting "naturally" if we did so in a socially accepted way. Again, this definition of "natural" is confined to the limits within a particular context....
