On the first part, I must apologize for my lack of specificity. When I used the words "based on," I really should have said "based wholly on." Yes, new science derives from the findings of old science. But that old science can still be independently verified. What was observable fifty years ago is still observable today, and experiments can be repeated. Contrariwise, I cannot walk on water, raise the dead or part seas. I am no prophet and know of none existing today who can perform miracles. Therefore, modern religion is based wholly on past testimony, where science is not.Zen Toombs said:I love that comic. And I'm sorry to be that guy, but science is also based upon written and oral transmission of past testimony. Scientific studies are based upon the research that has already been done, which is why we comb through journals for relevant articles.
Additionally, scientists are placing their faith that the evidence of their senses is true, and that the evidence from their measurements is correct, and that the evidence given to them by others who were using rigorous methods is correct. These are very reasonable and basic assumptions, but in order to progress you need to assume at least some of these things. And if you are assuming something, you are taking it on faith that it is true.
I want to reemphasize that these are small and extremely reasonable assumptions, and that scientists do what they can to minimize the effects of those assumptions (double checking unusual data, repeating previous experiments, etc), but they are still making assumptions and still working on faith that those assumptions are true.
On the second part(and someone else who quoted me earlier made a similar mistake), you are confusing science and philosophy. They are not the same thing. You could just as easily say that scientists can only assume that god isn't fucking with them and leaving fake dinosaur bones in the ground for us to find. Science doesn't require that I constantly check to make sure that I exist as I think I exist any more than it requires that I consult the book of Acts before conducting experiments. Don't cross streams.
