It is true of their corporate actions, such as political decisions, and it is true of their personal lives. The results of their thought world flow through their fingers or from their tongues into the external world. This is true of Michelangelo's chisel, and it is true of a dictator's sword. People have presuppositions, and they will live more consistently on the basis of these presuppositions than even they themselves may realize. By presuppositions we mean the basic way an individual looks at life , thier basic world view, the grid through which he sees the world.
Presuppositions rest upon that which a person considers to be the truth of what exists.
People's presuppositions lay a grid for all they bring forth into the external world. Their presuppositions also provide the basis for their values and therefore the basis for their decisions. An individual is not just the product of the forces around him. He has a mind, an inner world. Then, having thought, a person can bring forth actions into the external world and thus influence it.
