- A sphere (from Greek σφαῖρα, sphaîra) is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. Formally, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and r is the sphere’s radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.

This work, Mandate for Leadership 2025: The Conservative Promise, is a collective effort of hundreds of volunteers who have banded together in the spirit of advancing positive change for America. Our work is by no means the comprehensive compendium of conservative policies, nor is our group the exclusive cadre of conservative thinkers. The ideas expressed in this volume are not necessarily shared by all. What unites us is the drive to make our country better.
