But where did he say anything about prediction?EXACTLY! Every scientific statement, especially those which predict are based on observation. I even gave a meteorological example.
A lot of scientific statements are predictions, not observations. Hence, his claim that "Every scientific statement" can be reduced to an observation is wrong.
You are confusing "based on" with "exclusively". Deliberately, I would guess. Lewis said "Every scientific statement" can be reduced to an observation, which is wrong. To claim every scientific statement is ultimately based on observations would be fair enough.So you think Lewis was wrong, since you think scientific predictions are NOT based on observation? How do you THINK they are made? By guessing? By magic?
My position is that science involves both observation AND prediction, so I will not be bothering to address your straw man.Yeah, right. Explain how that is done without any observation.
