Competence, like truth, beauty, and contact lenses, is in the eye of the beholder. – Laurence J. Peter

Beauty depends on size as well as symmetry. No very small animal can be beautiful, for looking at it takes so small a portion of time that the impression of it will be confused. Nor can any very large one, for a whole view of it cannot be had at once, and so there will be no unity and completeness. – Aristotle
