The true key to philosophic mathematics is the famous Forty-seventh Proposition of Pythagoras, erroneously attributed to Euclid. The Forty-seventh Theorem is stated thus: In a right-angled triangle the square described on the hypotenuse is equal to the sum of the squares described on the other two sides. The Forty-seventh Problem is an important Masonic symbol and because of its close connection with the builder’s art is often called the “carpenter’s theorem.” It is believed that many of the complicated mathematical details of the Great Pyramid were based upon now unknown applications of this theorem. The Forty-seventh Problem is the key to the relationship between the three major parts of man: spirit, body, and soul.
