I suppose what I'm indirectly asking is whether you feel that certain scientific facts may provide some amount of insight into more philosophical arguments (and vice versa)?
As Kierkegaardian as I would like to be, I'm afraid I still harbor modern, even borderline...gulp...Hegelian tendencies, which shall be reflected in the following discussion. However, I believe I can spin my modern tendencies in a MacIntyrean direction, so as to allay any betrayal of dear Kierkegaard...so, here goes.
I believe that a large part of your answer involves digging into your own assumptions about ontology/epistemology. "Scientific facts", and more specifically, "facts", assumes traditions from the late 17th-early 18th centuries, involving characters such as Locke and Hume. If you assume "facts" necessitate experimentation and experience, then yes, scientific method and philosophy intersect at the corners of Locke and Hume. In fact, one could easily argue (keeping in mind pre-Socratic philosophy) that "science" as we know it has always been in the realm of philosophy.
However, I would also issue a warning in assuming strong relationship between the two fields. The general public takes for granted the modern idea that "fact" denotes experience and experimentation, while also adopting modern tendencies to jettison any withstanding tradition in favor of experience and experimentation. Remember that philosophy offers a much wider perspective of reality (or "fact") than the narrow field of vision projected Locke and Hume. Your example of Quantum Mechanics brings to mind more abstract notions of viewing the world, as we have no immediate experience with quantum particles. Thus, to assume Quantum Mechanics intelligible, one ought at least give Aristotelean metaphysics a try. Both are abstract notions of reality based on observation, yet coming from two divergent worldviews. My point is that philosophy and science can easily dialogue, as long as both understand their assumptions and can maneuver in some common ground. Otherwise, you might be trying to comment on a Hindi riddle in Spanish, where both sides think the entire world speaks their native tongue.
