    • Platonic Pertaining to Plato (about 427-347 b. c.), or to his doctrines. Reference to the school of Plato and to his followers is more usually expressed by the adjective Platonistic. Plato wrote in dialogues, which are equally admirable from a literary and from a philosophical point of view. He held that the object of philosophy is beauty; that without a deep sense of ignorance no man can philosophize; that judgments of common sense are open to doubt; that the senses may err, and at best can afford only likelihood (ει\κασια); that experience (δο\ξα), built out of perceptions, though safer, does not know the reasons of phenomena; and that man is the measure of things, not in his experience of particular facts, as Protagoras would have it, but in his knowledge of reasons, which alone is ennobling. Philosophy according to Plato has three blanches—dialectic, physics, and ethics. Dialectic, the art of discussion, proceeds by definition and division. Division should be by dichotomy. He holds strongly to the truth of cognition; the process of mind and the process of nature are one. Neither the Eleatic doctrine that all is One, and the Many mere illusion, nor the Heraclitnn doctrine that there is only a fluid manifold without unity, is the truth; there is a mixed being (μικτη\ ουὀσια): being has an eternal and an evanescent element, and only a compound of these can be an object of science. The one in the Many is the Idea, the active force prescribing regularity (as we should say, the law of nature), which in supercelestial place subsists while individual cases arise and perish. The ideas make up an organism, or living system (ζῷον). They are themselves regulated by an idea of a teleological character, the Good, or ultimate purpose of all things, identical with Reason, the true Being (ο\ντως ο\ν), the One, King of heaven and earth, which, immutable, draws all things toward itself. This Reason is God, who is related to the ideas as a poet to the ideals he has created and intends to embody. That other element which in the actual condition of things in this world has not yet been eliminated so as to leave pure Reason is extended quantity (μικρο\ν) or body (σῶμα), nearly Aristotle's matter (υ\λη). This is the secondary principle (συναιτιον) of the universe. God, the father, implants the seed of the Good in space, the mother, and without his further intervention the Cosmos, the only begotten son of God, made in his likeness, grows up. This is a second blessed god, instinct with Reason. Plato was a political philosopher. He abhorred alike the sway of oligarchy and of democracy, and still more the outcome of the latter, the one-man power—tyranny. He believed in aristocracy supported by an iron socialism. The relations of the sexes should be so regulated as to stop all increase in the population, which should be limited to 5,040 households. Private property and family relations should be abolished. Three classes should be recognized—workmen, soldiers, and lawyers. The education of a lawyer should begin with music, gymnastic, and mathematics. In his thirtieth year (up to which age he should be seen and not heard) he is to begin the study of dialectic. His education should be completed at the age of fifty, when he is to take his share in the government. The above is an outline of the general views of Plato; many of his special opinions are celebrated. He strongly maintains the immortality and previous existence of the soul. The tie which holds body and soul together is music. Virtue is not natural, nor can it be commanded by the will, but it is the result of discipline. The cardinal virtues are wisdom (σοφία), courage (ἀνδρία), prudence (σωφροσ, σ1ύνη), and justice (δικαιοσυνη). The unjust alone prosper; the perfect man would suffer on the cross. Reason resides in the head, desire in the abdomen, prophesy in the liver. Time is an image of eternity; it is produced by circular motions. Nature abhors a vacuum. Like attracts like. The constellations and the earth are living divinities. Plato was a mathematician, and is said to have invented the ancient method of analysis. His thoughts constantly show the influence of mathematical studies, and the desire to import mathematically distinct conceptions into philosophy. Aristotle, who was Plato's scholar, declared that the Platonic ideas were numbers. Plato no doubt attributed active virtues to the ideas of One, Two, Three, and Four.

Even the enrapt vision gone,
The Platonic fury it has fed upon
Hears love's sigh on every wind,
Looks in an endless urn that now discloses
Embers of joy, ashes of roses.

Cyclic $n$-gonal Surfaces
The constraints due to S being a quasi-platonic surface are not well known at this time other than to mention that the signature of A is quite restricted, and the potential for application to dessins.

We begin with the following theorem that excludes all but the full Platonic symmetry groups as candidates for the symmetry groups of regular polyhedra of index 2.
Regular Polyhedra of Index Two, I
Finally, we refer to for a proof that the rotation subgroups of the Platonic symmetry groups can also not occur as symmetry groups of regular polyhedra P of index 2.
Regular Polyhedra of Index Two, I
Let S be a Platonic solid of type {r, s}, let {v, e, f } be a flag of S, and let T be the triangle whose vertices are v, the center of e, and the center of f .
Regular Polyhedra of Index Two, I
The vertices of a regular polyhedron P of index 2 are located at the vertices of a single Platonic solid, a pair of aligned or opposed Platonic solids, a cuboctahedron, or an icosidodecahedron, in each case sharing the same symmetry group.
Regular Polyhedra of Index Two, I
We suppose, as before, that P is a regular polyhedron of index 2 with vertices coincident with the vertices of a single Platonic solid, a pair of aligned or opposed Platonic solids, a cuboctahedron, or an icosidodecahedron.
Regular Polyhedra of Index Two, I
We noted earlier that if the vertices of P are those of a centrally symmetric Platonic solid then no edge of P can join two opposite vertices, for if so then that edge would subtend at least three faces under the rotational symmetries of the Platonic solid.
Regular Polyhedra of Index Two, I
Since then S is a Platonic 1 )2 ∈ G+ (P ) = G+ (S ), so modulo G+ (P ) it suffices solid and G(P ) = G(S ), we have (σF to describe a face shape by [a, b].
Regular Polyhedra of Index Two, I
Then, by Lemma 4.4 and the analysis preceding it, the vertices of P are located at those of a pair of similar, aligned or opposed, Platonic solids, S and S (cid:5), sharing with P the same symmetry group and in particular the same center, o, and axes of rotation.
