Faith is a belief, conviction, held without the support of evidence, sometimes held even in the face of evidence to the contrary....
....Like believing that the material universe is eternal.
While our observations indicate that's a viable hypothesis, we don't hold it on faith. It may or may not be true. If new evidence more powerfully indicates matter is only temporary, we would be more likely to consider that true- but we still wouldn't consider it
absolutely true.
....Like believing that all explanations must be natural explanations.
Show us something you can explain supernaturally. We might change our minds. (But we won't be holding our breath, waiting.)
.....Like preaching that the Cosmos is all that is or was or ever will be.
That's just a re-statement of your first point; and we
hypothesize that it's true, we don't 'preach' it.
.....Like teaching that the universe can create itself out of nothing.
Hold on. If the material universe is eternal, it's uncreated. Can't have it both ways. (Do you think God created himself out of nothing?)
.....Like believing the Christian faith is not based on evidence.
"We have heard talk enough. We have listened to all the drowsy, idealess, vapid sermons that we wish to hear. We have read your Bible and the works of your best minds. We have heard your prayers, your solemn groans and your reverential amens. All these amount to less than nothing. We want one fact. We beg at the doors of your churches for just one little fact. We pass our hats along your pews and under your pulpits and implore you for just one fact. We know all about your mouldy wonders and your stale miracles. We want a this year's fact. We ask only one. Give us one fact for charity. Your miracles are too ancient. The witnesses have been dead for nearly two thousand years."
-Robert Ingersoll
.....Like believing that faith does not have a place in your worldview.
There's senses of the word 'faith' that we skeptics cheerfully admit to having. We can be, and have, faithful friends. We can act in good faith. The secular meaning of the word is a close cognate of honesty, and honor, and I don't deny the virtue of those ideas.
Evidenced faith, based on experience and reasonable trust in one's fellows, is nothing to sneer at- as long as one realizes that it can be mistaken.
But in the religious sense- absolute, blind, and unquestioning Faith, which I normally specify by using the capital F- it's no virtue at all.
