Clearly when we do science we make these assumptions but they cannot be proved to be true. For all we know, the scientific laws may all be different tomorrow; for example the speed of light may change. The idea of a rational cosmos is an ancient one. However, it was Christianity that revitalized the idea by acknowledging that God made the universe according to divine reason so that the universe is therefore a logical and rational place, and we can come to understand it as we are made in the image of God. This means that in a small way we have the power to reason and comprehend the universe, and thus achieve certain goals.
David Glass, physicist and philosopher, comments: What about atheism? How could it account for the order in the universe? Could a scientific explanation be given for it? It seems not, since the order is found in the scientific laws themselves. We need order for intelligent beings to exist, but there will no doubt be some things we find difficult to understand, as any God who has the power to create the universe would have ways and thoughts higher than our ways and thoughts
As we shall see later, quantum mechanics as it is currently theorized fits into this difficult category where ideas are non-intuitive, though a more intelligible theory may one day replace it. There are those who would say that science is the source of all truth.
