With the Compasses and Scale, we can trace all the figures used in the mathematics of planes, or in what are called GEOMETRY and TRIGONOMETRY, two words that are themselves deficient in meaning. GEOMETRY, which the letter G in most Lodges is _said_ to signify, means _measurement_ of _land_ or the earth--or Surveying; and TRIGONOMETRY, the measurement of triangles, or figures with three sides or angles. The latter is by far the most appropriate name for the science intended to be expressed by the word "Geometry." Neither is of a meaning sufficiently wide: for although the vast surveys of great spaces of the earth's surface, and of coasts, by which shipwreck and calamity to mariners are avoided, are effected by means of triangulation;--though it was by the same method that the French astronomers measured a degree of latitude and so established a scale of measures on an immutable basis; though it is by means of the immense triangle that has for its base a line drawn in imagination between the place of the earth now and its place six months hence in space, and for its apex a planet or star, that the distance of Jupiter or Sirius from the earth is ascertained; and though there is a triangle still more vast, its base extending either way from us, with and past the horizon into immensity, and its apex infinitely distant above us; to which corresponds a similar infinite triangle belo _what is above equalling what is below, immensity equalling immensity_;--yet the Science of Numbers, to which Pythagoras attached so much importance, and whose mysteries are found everywhere in the ancient religions, and most of all in the Kabalah and in the Bible, is not sufficiently expressed by either the word "_Geometry_" or the word "_Trigonometry_." For that science includes these, with Arithmetic, and also with Algebra, Logarithms, the Integral and Differential Calculus; and by means of it are worked out the great problems of Astronomy or the Laws of the Stars. * * * * * Virtue is but heroic bravery to _do_ the thing thought to be true, in spite of all enemies of flesh or spirit, in despite of all temptations or menaces. Man is accountable for the _up_rightness of his doctrine, but not for the rightness of it. Devout enthusiasm is far easier than a good action. The end of thought is action; the sole purpose of Religion is an Ethic. Theory, in political science, is worthless, except for the purpose of being realized in practice.
