What does science say

You will never hear me say or see me write, "Science says..." First I don't believe there is anyone named "Science", and even if there were, he would say, at most, "Such-and-such a theory stands unrefuted with the following supporting observations at this time," and never use the word "true" about a scientific statement. Second, what is held to be true is always a tentative conclusion. Scientific statements must by their very nature be falsifiable, and thus may be demonstrated to be false in the next instant.

The occurrence of "Science says..." or "Science has proven..." in a popular organ or a public debate virtually guarantees that what follows is untrue and probably a swindle.
