Exactly correct. Which is why I feel that scientists should all be persons of faith (as indeed so many are). After all, dont we all pretend that we know something we really arent sure about? The last scientist who claimed to know anything absolutely died in the early part of the last century. This is well known in physics, after quantum mechanics, but its no less true in biology. I was sure I knew that humans must have about 100,000 genes. Oops, I guess my faith that I (and all the other geneticists) knew how genes and their products worked was misplaced on that one. I used to take it as an article of faith that all mutations were random. Looks like another mistake.
Now, you will say that that is the beauty of science, it corrects itself with new data, while religious folks never do that. That’s what I thought during all my atheist years, but guess what? That faith
based belief is also wrong. I find that religions and principles of religious faith are about as mutable (maybe more so) than scientific dogmas. Witness the resistance to the heresy of neutral drift and punctuated equilibrium.
So yes, faith is believing something you arent sure is true, because we arent sure anything is true other than some fairly trivial stuff. When it comes to big questions, faith and science are not only on an equal footing, they are generally pretty well in line with each other. Halleluljah.
