You're talking about car keys you put somewhere, I'm talking about exploring the unknown.
There's nothing "known" about the location of my car keys, at the moment.
We were talking, actually, about the role of faith in establishing objectivity, while exploring the unknown. I observe that it is counterproductive in the exploration itself, in many simple instances of such exploration (it's difficult to avoid "finding" what one strongly believes in) and interferes with what most people term "objectivity" in any case I can think of.
But as you note, it contributes to motivation - exploration is a time and energy intensive activity, only occasionally fruitful, and most who actually do the work of exploration begin with a sense of what they expect and hope to find.
Hence the necessity, when exploring the unknown, of some means of discarding the reified expectation that is the most common finding of explorations. For this, reason has proven invaluable. Faith that will not answer to reason has no claim on respect or consideration, then.
In the case of car keys, it's Sherlock Holmes's maxim: when the impossible has been eliminated (and there's no BS about it - after the third check of the coat pocket, they aren't there, period, nothing about "imminance" or "transcendent presence") what remains (the ignition, draining the battery all night) must contain the truth.
In the case of deity, eliminating the impossible involves clearing a much higher bar - people really, really
want to believe those keys are in the coat, and if it takes quantum tunneling between pockets to put them there, quantum tunneling has to be considered and eliminated to satisfy Holmesian analysis. That's impossible. So the other forms of reasoning, the other legit techniques of rhetoric and persuasion, come into use.
And rhetoric, reason, is what it is - - - not science. Dawkins is not doing science, in the God Delusion.
