Apologies for the lateness in reply, I have educational commitments I have to attend to.
Pessimists focused traditionally on quieting the Will, the unrest that is the metaphysical kernel at the heart of existence. What you discuss is what I call "contingent harms"- they are circumstantial harms that humans face based on their biological/psychological/social/cultural/environmental circumstances. Traditionally, pessimists are concerned with the kernel. To admonish them for not focusing on contingent harms, is a bit misleading as Pessimists rarely focused on contingent harms- it is what makes a Pessimist a Pessimist. It is like admonishing a cat for not being a dog. — schopenhauer1
I will grant that the metaphysical "kernel" as you mention is at the heart of pessimism, but I'll also argue that it's not just the "Will" (as that's Schopenhauer's thing), and neither is it
exclusively these kernels.
In fact I would argue that contingent harms are
necessarily part of human existence. To exist means to be harmed in some random and unpredictable manner. Schopenhauer himself used many examples of contingent harms - think back to his analysis of the pain of the prey and the pleasure of a predator. This isn't the "kernel" he speaks of, but it's nevertheless an example of a contingent harm that characterizes an unfairly and unequally-distributed experience machine we call life.
Karl Robert Eduard von Hartmann — schopenhauer1
Great stuff by von Hartmann, I had forgotten his name and couldn't seem to find him. Bit of an obscure philosopher, unfortunately, who nevertheless mirrors a lot of my own thinking.
If everyone simply went off to help in whatever situation they can, that would leave little time to develop things and improve them in terms of technology, ideas, social change, etc.. There are so many ways that people create utility unintentionally. Who are you to decide which actions lead to the greatest good? The sports-watching couch potato could think of something on his spare time that immensely increases the utility of people and animals around the world, that he would never have done simply by directly providing aid/volunteer opportunities. In fact, if this guy volunteered, he would have not thought of that novel innovation that increased utility way more than direct aid. Further, the factors that lead to outcomes for greatest utility are so numerous, there is no reliable probability one can calculate to account for everything in terms of which action leads to greatest utility. Instead, direct aid would simply be following one's own notions of what's good, not bringing about the actual greatest good. This then would mean that one would simply follow one's own inclinations, neuroses, and etc. and not what is logically the best thing to do to increase utility at that particular time. — schopenhauer1
Well, again I mentioned earlier how it's not that we all have to get up and slave away doing things. There's charities that we can donate to and local events that we can participate in to help out the community and society at large.
You mention how many good things can come unintentionally. Yet I would argue that you're missing the far greater goods that come with intentional focus! For every lazy sports-watching couch potato that comes up with a marvelous new idea, how many
other lazy sports-watching couch potatoes
don't, and live their whole lives with their asses glued to their seats?
The fact is that, just as you said,
we don't know how to perfectly maximize utility.
We don't know whether or not excessive luxury or leisure will result in these marvelous new inventions that will save countless lives. So the best thing we can do, given our epistemic stance, is to do what we
do know will help. Not sit around waiting for inspiration to pop into the minds of your everyday hill-billy in Alabama.
Even the starving Ethiopian, if he/she was ethical himself would hope that you would also pursue a life with some happiness that goes beyond helping him/her.. even if he/she appreciates the immediate aid you gave him right there and then.. The hypothetical starving Ethiopian hopefully has ends THEY would like to pursue.. just like you or I.. Pessimists are under no more obligation to have a tormenting life of than others merely because they see life as unrest. — schopenhauer1
True, I accept that the Ethiopian would be ethically obligated to want you to also be happy, even if she's starving. This goes back to Cabrera's analysis of pain, specifically torture and extreme suffering. He draws from Hannah Arendt and talks about how pain is isolating and controlling. Cabrera describes it as one of the ways a person becomes ethically disqualified.
For example, we cannot honestly expect a spy to keep his secrets if he's being horribly tortured by the enemy.
Even if what this man does (spill the beans) is immoral and leads to countless deaths, we can't honestly blame him for his blunder. It's
too extreme to act ethically under these circumstances.
Now, again before anyone else jumps on my tail on this, I personally believe we do have ethical obligations towards those who are suffering greatly (what Maw called "gratuitous suffering") within a certain threshold and some other minor qualifications. But you can disagree with this without changing anything about the OP, as the OP sets out to describe the differences between active and passive pessimism. The latter being more contemplative, removed, aesthetically-oriented and redemptive, the former being more pragmatic, radical, forceful and openly-disgusted with the world at large. For the active pessimist, then, there's really no place for any talk of "aesthetics" as a top priority or grand schema. There's really no place for "TRUTH" unless it's instrumental to our own ends. There's really no place for comfort, security, or loftiness unless it's in the service of some greater goal.
If I had to try to summarize it, then, it would be that the passive pessimist, when confronted with the reality of existence, tends to retreat from the world, while the active pessimist tends to swallow the bitterness and remain a player on the field.
So then, from a more personal view, as I tried to explain earlier, I don't see how these great fantastic amazing things like "TRUTH" or "A E S T H E T I C S" or "Transcendence" or any of that crap legitimately "fits" in the worldview of a pessimist. It's the same thing when a tragedy happens and someone says "look on the bright side!" and you just want to slap them silly for saying such a stupid thing. There is no beauty in this world, at least no beauty that doesn't come with a heavy price - and what sort of beauty is that? It's this kind of "clinginess" of passive pessimism that makes it what it is, like it accepts pessimism but doesn't "go all the way". One can wonder if someone like Schopenhauer would have pushed that big red button to end the world immediately and painlessly, or if he would have rather not done this for some abstract idealistic ethics or because he wanted to pursue his metaphysics more or whatever. I get the feeling, when reading his work (and others'), that they actually enjoy complaining about the world, in general at least, and it seems out of place and disingenuous. At least to me.
Assuming there aren't any objections, then, I would argue that unless someone is willing to embrace hypotheses like world destruction or biological sterilization or what have you, they really have no business talking about the suffering that inevitably calls for such action. It's like saying there's a fire down the street but being opposed to calling 9-11: like, then why did you even bring it up? Nobody really seemed to have gone far enough, from my ethical perspective, and it's disheartening. Nobody seemed to have the stomach to seriously consider how their pessimism might be implemented. The state of the world doesn't call for calligraphy or fine cuisine. It's out-of-place, like wearing a wedding dress in a war zone. It just doesn't fit, simple as that.
