Evolutionary cosmologies may begin simply as rival evolutionist theories —
alternative causal explanations for these observed phenomena of development, change, and transformation.3 An evolutionist theory becomes an evolutionary cosmology whenever the favored evolutionist theory is extrapolated from its original context as an account of geological or biological change, and made to serve as an overarching cosmological
category, such that «evolution» in some idiosyncratic sense becomes the basis for a systematic and unified interpretation of a wide array of
diverse phenomena beyond the domains of biology and geology.
Section III of the Diagnostic and Statistical Manual of Mental Disorders — 5th Edition (DSM - 5) offers an
alternative model for personality disorders intended to address the scientific problems of the categorical system (currently preserved in Section II), including within - diagnosis heterogeneity, excessive overlap with other diagnoses, and arbitrary
categories that were developed from
diverse traditions and clinical observations.
