To demonstrate not only the difference between scientific/descriptive knowledge and metaphysical/prescriptive knowledge, but also the greater degree of both accessibility and authority in the latter, consider the following:
There are scientific experiments which everyone knows (accessibility: tick) without question (authority: tick) simply should not (prescriptive: tick) be performed ((and there honestly is no need for me to give examples of such experiments)).
EDIT: lest it need to be said, the previous post makes no claim, of course, for human omniscience in any area.
Just watched The Changeling with my wife (‘endured’ would be the term she’d use!), and really enjoyed it. There are some real gut-wrenching moments in there, which I won’t elaborate on here.
One thing I found interesting was the particular (and familiar) feeling of deep satisfaction and relief I (and my wife – and anyone with a pulse) when the ‘code 12’ women were freed from the mental hospital, and when the lawyer offered to defend her pro bono. It’s just that familiar, deep-seated, very human feeling we all get when the right thing is done – when a horrible injustice is righted. The opening scene of Amistad, where the slaves on the slave ship break loose and take over the ship, though violent and bloody, also provoked that same feeling – that kind of fist-pumping ‘yeah!’ feeling. Emotions aren’t infallible, and in terms of epistemology I don’t think any source of knowledge is (reason, logic, etc.); but sometimes they (emotions) can be very, very good conductors of Truth.
And I love how immediate, every-day, down-to-earth, and universal these kinds of emotions are. No philosophy degrees needed here, no deep pondering or reflection, just deep, gut-level ‘knowing’ that – though we don’t know everything – we know that we know that we know ‘this is right’.
