“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, his 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 the decisions…most people catch their presuppositions from their family and surrounding society the way a child catches measles. But people with more understanding realize that their presuppositions should be chosen after a careful consideration of what world view is true. When all is done, when all the alternatives have been explored, ‘not many men are in the room’—that is, although world views have many variations, there are not many basic world views or basic presuppositions.” (Schaeffer, How Should We Then Live?, 20)
