On another thread, npetreley has accused scientists of being blinded to alternative hypotheses by their committment to methodological naturalism. I'd like to explore this idea a little bit and see if npetreley can show us how science ought to work.
For this little exercise, I'd like to focus on a topic not directly related to evolution: the cause of human diseases. Let's pretend that everything we know about medicine hasn't been discovered yet. Let's say that I am a rich and benevolent king and, since I am so belevolent, I want to spend some of my vast riches to help my subjects. Many of my subjects suffer and die early deaths due to disease, so I choose to embark upon a project to determine the cause of disease, with the thought that this knowledge will help me to identify ways to prevent and cure disease among my subjects.
The first thing I do as King is to summon all the wise and learned women in my kingdom to discuss all of the various hypotheses of the cause of disease and to identify the handful of hypotheses that are most promising to investigate. After many weeks, much arguing, and many boxes of the royal Krispy Kremes, the learned women emerge with their two best hypotheses as to the cause of human disease:
a) disease is caused by evil spirits who possess our bodies
b) disease is caused by microscopic life forms who invade our bodies and damage its systems
Thrilled with results of my project so far, I summon my chief science officer, npetreley. World renowned for his non-materialistic world view, I have utmost confidence that npetreley will soon be able to discover the true cause of human disease. I present him with the best hypotheses of my learned women and offer him all of the financial and capital resources of my kingdom.
Given the vast committment I have made to the project, a last minute doubt enters my mind. I seek reassurance from science officer npetreley with one last question: "Excuse me, Sir Petreley, but how is it exactly thou doth propose to determine which of the fine hypotheses is the true cause of the human diseases which doest plague my people?"
