Absolutely! There are any number of scientists out there who believe passionately. Which does not serve to make them less (or more) intelligent. Newton btw is a
really bad example to use, not only was he living at a time when it was very difficult not to be a believer if you wanted to avoid opprobrium, but also he believed all sorts of things that were quite (and by "quite" I mean "extremely") wrong; his personal theology, like Leibniz's, would be nigh on unrecognisable as having anything in common with standard Christian belief too. From what I can gather, Newton steered very closely to the Arian Heresy...
But (and it's a big "but") a scientist's personal belief has no place in doing actual science. It can serve as an impetus obviously (as in the case of the Pillars of Islam, one of which is for the individual to learn as much as possible about God's creation), but as soon as it starts to influence the work they do, they cease to be doing science. The supernatural is not a postulate when applying the scientific method. It can't be because science is about looking for material causes; once you admit the supernatural, all bets are off. So science can say nothing about the supernatural except to exclude it from particular phenomena that are seen to have natural (i.e. material, in a rather specialised sense of the word) causation.
This is, of course, why the ID guys try to convince neutral observers that they're actually involved in scientific endeavour by carefully not specifying (or rather hilariously not, in at least one case), to their science audience at least, what or who their proposed Intelligent Designer is. The flaw being that if their theoretical "other" designer is not supernatural, you're left with the same problem you started with and you've learned exactly nothing. They are also deliberately quiet on drawing inferences about what can be learned of the nature of their theoretical designer and what constraints they might work under. Which makes the excercise both rather futile and somewhat disingenuous. For their religious audience they're pretty specific about their mission (as evidenced by the "Wedge Document" and the whole "cdesign proponentists" imbroglio) Which makes the excercise more one of obfuscation and completely dishonest at it's core, but there we go...
Of course they haven't actually
produced any science, they're more concerned with whinging about the "great conspiracy" of evilutionists; but that's very obviously not what they want to get out of it...
I suspect you're having a go at Dawkins here and, whilst I hate to defend him because he is a bit of an arse on occasion, if you look at the work he did back when he was productive (which, interestingly enough, was not on the various links between animals but more about the survival strategies of individual genes and their effects on the entities that they build) he didn't introduce his personal philosophy into that, he let the work and concepts speak for themselves. Which is how you do science. And this work has been built upon, by people who cover the spectrum of beliefs, and informs the subject (to a lesser or greater extent, depending on who you speak to; everyone disagrees on the details
) to this day. Personally, I far prefer the books of his where he keeps the philosophising down to a minimum and just gets on with the job of explaining the concepts.
Good grief, I'm going edit crazy here...
Anyway, the issue with science it that it works and it goes on working right up to the point that it stops working. There's a quote, which I can't place at the moment, that says that you know you have a mature scientific theory because it actually tells you the conditions in which it doesn't apply (in physics it's usually where you can't get rid of all the infinities that pop up - General Relativity in the strong limit does this...) The process is inherently flawed, but paradoxically this flaw is one of its main strengths; science is prepared to burn its bridges and learn from its mistakes when confronted with the world; it has to be, or you're not doing science. Have a look at the history of physics in the late 19th and early 20th Centuries; they thought they'd got the world pinned down, then all of a sudden Quantum Theory and Relativity come along and change everything at the deepest level possible. It's happened before and I would hope I live long enough to see it happen again; I like the uncertainty.
For a lot of people, that's unconscionable behaviour, because what they want is certainty. Arguably this is the religious urge at play; religions are always right. It's always God at the end of everything and that doesn't and can't change because it's built in from the outset.

If an opinion contrary to your own makes you angry, that is a sign that you are subconsciously aware of having no good reason for thinking as you do. If some one maintains that two and two are five, or that Iceland is on the equator, you feel pity rather than anger, unless you know so little of arithmetic or geography that his opinion shakes your own contrary conviction. … So whenever you find yourself getting angry about a difference of opinion, be on your guard; you will probably find, on examination, that your belief is going beyond what the evidence warrants.
