By presuppositions and assumptions it is meant the basic way an individual looks at life, his or her basic world-view, the glasses or the grid through which he sees the world.
An example of a foundational worldview presupposition—or, starting point– is the belief (or assumption) that things are billions of years old. This, of course, is quite different from the detailed genealogy data in the Old Testament—particularly in the book of Genesis–and the Creation account found at the beginning of its historical narrative, which points to an age of well less than 7,000 years.
People have presuppositions, and they will act on the basis of these presuppositions more than even they themselves may realize. By presuppositions and assumptions it is meant the basic way an individual looks at life, his or her basic world-view, the glasses or the grid through which he sees the world. They rest upon that which a person considers to be real history, or the truth of what exists. Our presuppositions–or starting assumptions—establish a starting point or framework for all we bring forth into the external world, and how we interpret things. They (or it) also provide the basis for our values and . . . consequently the basis for our decisions, and how we live our lives.
Thoughts are things. “As a man thinketh, so is he,” is not just true, it is more than profound. The two foundational worldview options mentioned in the first paragraph are in direct opposition. They cannot both be true.
What if our starting presupposition, or assumption, is wrong?
