Natural Numbers
The positive integers, 0, 1, 2, 57, etc.
Origins
All numbers used in the Bible are positive integers, for example, 20 loaves of bread, 4 horsemen of the apocalypse, 50 ways to leave your lover. By inference, all such numbers are referred to as "natural". Other other numbers are equated with progressive degrees of unnaturalness. The negative numbers are commonly associated with basic evil. The CIA uses negative numbers to denominate the ranks of terrorist groups, -1 is an ordinary member, -2 is a squadron leader, etc. This is because there is no lower bound to the negative numbers and thus no limit need be imposed on their evil[1]. The rational numbers are the next most unnatural numbers. Rationality runs directly counter to naturalness, see evolution vs creationism, Einstein vs Newton. Irrational numbers are the first numbers that cannot be formed from arithmetic operations of natural numbers and thus are the first unbiblical numbers[2]. Complex numbers are the most unnatural numbers. Recent research has suggested a link between homosexuality and complex-valued genetic base-pairs[3].
