Science is like a clock; all the cogs must fit together to function with success, and it functions in cycles (in the respect that one stage must be completed for the next to proceed).

I am a bit indifferent to the way of looking at science presented. While I can see the logic associated with it, I don't believe it is exactly necessary to pick one way of seeing it. I'm sure many successful (however they choose to define "success") scientists have looked at their work in both or either ways.
In addition, many people seek comfort in determining what is seen as the "truth." For them, truth provides stability and support in a sometimes unpredictable world. Similarly, some people rely on religion for this solace.
