‘Abdu’l-Bahá's teaching in this regard may be easily understood if one considers that "nature" sometimes provides examples that are unworthy of emulation by human beings. For example, the fact that some species eat their young does not mean that it is acceptable for human beings to do so. The Bahá’í concept of human nature is teleological; that is, there are certain qualities intended by God for "human nature", and qualities which do not accord with these are described as "unnatural" This does not mean that such aberrations may not be caused by the operations of "nature."
