In some quarters the very success of science has also lead to the idea that, because we can understand the mechanisms of the universe without bringing in God, we can safety conclude that there was no God who designed and created the universe in the first place.
However, such reasoning involves a logical fallacy, which we can illustrate as follows.
Take a Ford motor car. It is conceivable that someone from a remote part of the world, who was seeing one for the first time and who knew nothing about modern engineering, might imagine that there is a god (Mr Ford) inside the engine, making it go. He might further imagine that when the engine ran sweetly it was because Mr Ford liked him, and when it refused to go it was because Mr Ford disliked him. Of Course, if he were subsequently to study engineering and take the engine to pieces, he would discover that there is no Mr Ford inside it. neither would it take much intelligence for him to see that he did not need to introduce Mr Ford as an explanation for it’s working.
His Grasp of the impersonal principals of internal combustion would be altogether enough to explain how the engine works. So far, so good.
But if he then decided that his understanding of the principals of how the engine works made it impossible to believe in the existence of Mr Ford who designed the engine in the first place, this would be patently false - in philosophical terminology he would be committing a category mistake. Had there never been a Mr Ford to design the mechanisms, none would exist for him to understand.
It is likewise a category mistake to suppose that our understanding of the impersonal principals according to which the universe works makes it either unnecessary or impossible to believe in the existence of a personal creator who designed, made, and upholds the universe. In other words, we should not confuse the mechanisms of the universe with either it’s cause or it’s upholder.
The basic issue here is that those of a scientific turn of mind like Atkins and Dawkins fail to distinguish between mechanism and agency.
When Sir Isaac Newton discovered the universal law of gravitation he did not say, “I have discovered a mechanism that accounts for planetary motion, therefore there is no agent God who designed it.” Quite the opposite, precisely because he understood how it worked, he was moved to increased admiration for the God who had designed it that way.
