Features, philosophy: Features are fundamentally characteristics, however in the philosophical terminology according to Frege it has become natural to speak of (necessary) characteristics, but in objects of (contingent) properties. Objects do not have their properties necessarily, they can always be different. Concepts, on the other hand, have their characteristics necessarily. E.g. that circles are round is a necessary characteristic of the concept circle, but not a necessary property of drawn circles. It is, however, not the concept which has the characteristic itself, but the objects which fall under it._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. | |||

Stephen Jay Gould on Features - Dictionary of Arguments
I 264 Features/Gould: derived features stem solely from one common predecessor. A common primitive feature, on the other hand, cannot clearly refer to ancestry. For example, the presence of DNA in both ciliates and flatworms tells us nothing about their proximity to each other, because DNA occurs in all protists and metazoans. Hanson, for example, calls the "completeness" of the cilia a "permanent" feature that occurs in both flatworms and ciliates. Gould: however, completeness is an easily occurring evolutionary characteristic that can only be analogous. Limit: large animals cannot develop enough cilia on their relatively small surface to move their larger masses. The complete cilia of the flatworms could therefore be a secondary, adaptive reaction to their small body size. The tiny snake Caecum also moves forward on cilia, while all larger relatives have muscle contractions. IV 281 Feature/Evolution/Gould: here the attribution of key features is pointless. Features that determine genera under certain conditions can vary greatly among species within another group. There are no "constant species" or "constant generic features". >Evolution. _____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
