Individual semiotic systems interpreting their environment are not well understood from the externalist approach typical of the scientific method. Science constructs probabilities describing large populations of systems, not individuals. The Umwelt, as the individually experienced/created aspects of the habitat aspect of its population’s ecological niche, is given an internalist understanding within the framework of the compositional hierarchy. Vagueness is an important aspect of the internalist condition. It is selectively reduced momentarily by creative choices that can have a Peircean semiotic formulation, (...) and which are often unpredictable externally, thereby appearing to be chance events.

?Emergence? can be analyzed into evolutionary and developmental kinds. The latter can be further analyzed into intensional and extensional kinds of emergence. Evolutionary emergence occurs each time a uniqueness enters the world. Intensional emergence (supervenience) explicitly involves the categories of an observer. Extensional emergence (cohesion) is constructed as an attempt to see developmental emergence as a result of the imposition of larger scale constraints on a system. In all cases there is a sudden jump from pre?emergent to post?emergent stages so (...) that the transformation may be said to defy continuous description, which is also hampered by the fact that knowledge of properties of the pre?emergent condition alone does not allow us to predict post?emergent properties.
