Aristotle's geographical speculations anticipated by almost two thousand years the rationale behind Columbus' voyage. Ferdinand Columbus suggested that his father was familiar with the following passage: "Again, our observations of the stars make it evident, not only that the earth is circular, but also that it is a circle of no great size. For quite a small change of position to south or north causes a manifest alteration of the horizon. There is much change, I mean, in the stars which are overhead, and the stars seen are different, as one moves northward or southward. . . . All of which goes to show not only that the earth is circular in shape, but that it is a sphere of no great size: for otherwise the effect of so slight a change of place would not be so quickly apparent. Hence, one should not be too sure of the incredibility of the view of those who conceive that there is a continuity between the parts about the pillars of Hercules [the strait of Gibraltar] and the parts about India, and that in this way the ocean is one."
Anybody can become angry - that is easy; but to be angry with the right person, and to the right degree, and at the right time, and for the right purpose, and in the right way - that is not within everybody's power and is not easy.
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.
