That is arbitrary as well but has no real effect on your ability to separate such claims from scientific thinking
You seem to make a career out of missing points. I have never claimed that someone cannot hold two epistemological positions at once. People certainly do. I am saying that they are mutually exclusive propositions and that people who do so are being intellectually dishonest, either intentionally or unintentionally.
If you are going to argue for a position or against one, at least get a decent picture what said position is.
Then call it the bullshit box. It's still the same box and distinct from the "Science" box.
No. In order to be consistent, one needs to hold all truth claims to the same standard. What I meant by the Bullshit Box is probably more analogous to a trash can. If you are going to hold one set of truth claims to a standard of evidence, a "way of knowing" or an epistemological system you need to apply that to all truth claims. This means that if you are a scientist all truth claims need to be subjected to empirical scrutiny and evaluated by comparing them to what we can observe in the universe. It is not consistent to say "Truth Claim X requires a certain amount of evidence in order for me to accept it, but I am going to give Truth Claim Y a free pass"
What one should do, is casually discard truth claim Y unless it can be held to that same standard.
Now, does everyone do this? No. There is nothing stopping them from doing so, and their failure to do so does not invalidate their conclusion regarding Truth Claim X. However they are not being intellectually honest when they do so.
their holding of bullshit beliefs did not prevent them from holding scientific beliefs and, in fact, holding valid ones.
No. It did not. However that does not mean that they did so in a way that was intellectually consistent. People hold two mutually exclusive positions all the time. It causes something called cognitive dissonance, and the more clever a person is the better they are able to rationalize holding those mutually exclusive positions at the same time.
Take Kenneth Miller as an example. The man is a good cellular biologist. He holds the position that human cognition is rooted in brain structure and that human behavior evolved through the laws of natural selection. He also believes in an immaterial soul that controls and is cosmically responsible for your actions. It does not take rocket science to note that these two beliefs are mutually exclusive. However he has written an entire book called Finding Darwin's God where he lays out how he rationalizes holding these two fundamentally contradictory positions.
Similar situation with Francis Collins, though he is even nuttier, having seen a frozen waterfall in the mountains and literally knelt down on the spot to accept Jesus.
It wasn't until LaPlace came along with access to the work of all three that the problem was solved and it seems highly unlikely that being an atheist was instrumental in his ability to think about the problem in a different manner.
He was the first to not give up and attribute causation to God. Even if the others had no capability of finding some semblance of the answer, they still threw up their hands and said "god did it"
It is only harmful when combined with general stupidity that leads the user to try and force the stuff in their Religion box on the rest of the world... which, you may note, Serafine666 is not proposing to do.
And at no point did I say it was harmful. Only stupid. Religious people are evaluating the ethical truth claims of religion based upon the premises of secular philosophies anyway, whether they know it or not. For example, the bible tells them to stone homosexuals but you dont often see them do it now do you? They have concluded despite biblical command that doing so is wrong, but then give a contradictory portion of the bible the credit.
There's a reason why Newton's published works use geometric proofs and not calculus-based ones; calculus was a bleeding-edge piece of mathematics at the time, and using it in his publications would have left him open to (not unwarranted) attacks against the calculus as well as attacks against his physics results.
Granted. And it was an attic if I recall, not a basement. As a general rule physicists isolate themselves in attics, computer scientists in basements, and biologists in some form of hermitage.
