| 4535 | A 'species' is a stable phase of evolution, implying the false notion that evolution has a goal [Nietzsche] |
| Full Idea: When a 'species' appears, it is a phase in which evolution is not visible, so an equilibrium seems to have been attained, making possible the false notion that a goal has been attained, and that evolution has a goal. | |
| From: Friedrich Nietzsche (The Will to Power (notebooks) [1888], §521) | |
| A reaction: A penetrating explanation of a crucial that won't go away, and that still grips people's minds. Even if we all want a particular goal, evolution will ignore our dreams and go another way. |
| 17369 | We name species as small to share properties, but large enough to yield generalisations [Devitt] |
| Full Idea: Our explanatory purposes in introducing a name for a species demand that we draw the lines around a group that is small enough to share a whole lot of important properties and large enough to yield broad generalizations. | |
| From: Michael Devitt (Resurrecting Biological Essentialism [2008], 10 'Arb') | |
| A reaction: Grist to my mill. In this reaction slot (16th Oct 2013) I launch my new metaphysical school - welcome to EXPLANATIONISM! Folk metaphysics, and the best philosophical metaphysics, is entirely driven by the needs of explanation. |
| 17367 | Species are phenetic, biological, niche, or phylogenetic-cladistic [Devitt, by PG] |
| Full Idea: The four main concepts of a species are 'phenetic' (similarity of traits), 'biological species' (interbreeding and isolated), 'ecological niche' (occupying an adaptive zone), or 'phylogenetic-cladistic' (start and finish at splits in lineage) | |
| From: report of Michael Devitt (Resurrecting Biological Essentialism [2008], 4) by PG - Db (ideas) | |
| A reaction: [my summary of Devitt's list] Devitt attacks the whole lot, in favour of essentialism - the species being fixed by its underlying explanatory mechanisms. |
