Eudoxus said, in effect, that a point on the line is uniquely determined by its position among the rationals. |

Each continuous function from the real line to the rationals is constant, since the rationals are totally disconnected. |

Note that it is known that the boundary complex of a simplicial polytope has the WLP over the rationals. |

Keirsey and Bates also classify four subtype combinations as the four temperaments of Idealists, Rationals, Guardians, and Artisans. |
