The above point is fundamental to understanding why I don't like healing surges - they necessitate that the above understanding be discarded and replaced with an alternative understanding for what hit points represent (e.g. that hit points are a character's "ability to keep fighting" or something similar).
This may have already been talked about, but I haven't read the thread to the end, since I wanted to reply to Jameson. But, unfortunately, Hit Point loss, has never fully represented taking physical damage. Not with OD&D, 1e, 2e, 3.x, PF, 4e, not with any of them. Hit points have always been a very abstract concept that includes a bunch of factors, including, but certainly not limited to, physical health, mental health, endurance, vitality, ability to mitigate damage, glancing blows, luck, etc. Gary Gygax himself spoke about this, as far as I know, as early as the 1e DMG.
A few things I wanted to clear up.
First, the emboldened part of my previous post that you quoted wasn't me making any sort of statement about the game itself - it was my saying where I'm coming from on the issue of hit point loss and healing. For me, they always have been, and always will be, physical damage. What's in the books isn't really important on that score (though I personally think that the books agree with me, see below).
There are serious problems with thinking of HP as ONLY physical damage, more so than what you already spoke of. First and foremost, in my mind, if you take a sword hit that does 50% of your physical damage, how are you now able to continue fighting at 100%? I like to think of Boromir in LotR, when he takes the arrow in the chest. He's still conscious, he still has some motor activity, but he certainly cannot fight at 100%. He tries to fight of course, but as he keeps taking arrows, he becomes weaker and weaker.
See, I don't see that as having any impact on the question of whether or not hit point loss is due to physical damage whatsoever. The very nature of D&D combat is abstract, and so a lot of factors are simply not dealt with, such as hit locations, wound tracking, facing, combat fatigue, etc.
Saying that "hit point loss cannot be physical damage since it doesn't impact your fighting ability" is, to my thinking, a failure to follow the game's own brand of logic - combat damage has no secondary effects, because it can only model so much. Now, there are some special effects for various things like feats, spells, etc. But these are explicitly called out as having a special effect.
Here's a quote from the 1e DMG, written by Mr. Gygax himself. (It's the only one I could find in a short amount of time, without access to my books, and at work, but it should suffice).
It is quite unreasonable to assume that as a character gains levels of ability in his or her class that a corresponding gain in actual ability to sustain
physical damage takes place. It is preposterous to state such an
assumption, for if we are to assume that a man is killed by a sword thrust
which does 4 hit points of damage, we must similarly assume that a hero
could, on the average, withstand five such thrusts before being slain! Why
then the increase in hit points? Because these reflect both the actual
physical ability of the character to withstand damage - as indicated by
constitution bonuses- and a commensurate increase in such areas as skill
in combat and similar life-or-death situations, the "sixth sense" whith
warns the individual of some otherwise unforeseen events, sheer luck,
and the fantastic provisions of magical protections and/or divine
protection. Therefore, constitution affects both actual ability to withstand physical punishment hit points (physique) and the immeasurable areas which involve the sixth sense and luck (fitness).
Bolded area is key to understanding that HP do not completely reflect actual, physical damage.
We're taking very different things away from that particular passage.
What I got from that is that Gary is giving us narrative devices to explain why physical damage that's taken is comparatively less severe at higher levels, even when the amount of damage remains the same. In other words, he's not denying that the character is still taking physical punishment, he's just taking less of it due to things like luck, a sixth sense, divine protection, etc. allowing him to take, as Gary put it, "five such thrusts."
Those thrusts are still hitting, in other words, just not as palpably, due to purely narrative explanations. But they're all still physically damaging blows taken in combat.
Of course, it's ultimately something of a moot point anyway. Not only because that's the 1E interpretation (as opposed to 3.X, which was much more explicit in saying that hit point loss was physical damage), but also because quoting somebody else's ideas aren't going to make me say "Oh, I've been doing it wrong."
The OP asked why we don't like healing surges, and my previous post was me saying why I don't. Hit point loss in my games is physical damage, and regaining hit points is wound closure. Having characters non-magically experience a burst of healing as a voluntary action on their part is, quite simply, too out there for me to accept.
