I finally have a little bit of time to address some of these very interesting points you brought up.
I don't think that the practise of criticizing is as clear as you make it sound. To take your example, one can simply say that the dish is lacking something, "it doesn't taste the way I think it should", without even being capable of identifying the exact problem. There is no clear idea of "how it should taste", or of what is needed to make it taste that way. To determine that something is missing, and to determine what it is that is missing are two distinct procedures. It is the same in the example of sickness, the person who is sick may be able to say "I am sick", without having any capacity to diagnose the illness. — Metaphysician Undercover
I continue to think that in each of these cases the understanding takes its measure from some notion of wholeness or completeness, regardless of how difficult this may be to pinpoint or articulate. The acknowledgment of privation is what seems to motivate criticism of any sort from the get go. A general awareness of an absence (dish doesn't taste right) and a diagnosis of its specific cause (too much salt) seem precursors to the ultimate goal, which, at the very least, would appear to be the bringing about of an improved condition, i.e. something 'better'. We may obviously get stalled at some point in the procedure, even the first as you pointed out, but we rarely content ourselves with remaining at that stage if we can avoid it. It rather appears as though the entire process is guided in advance by our understanding of things like optimal health or a tasty dish, and if we were completely lacking in some vague notion or intuition concerning these things, then we wouldn't even be able to say that we were sick, or that a dish was somehow off.
Applying this to criticism of Donald Trump. We feel strongly that he's bad for America (general awareness), and the reason for this is a combination of his abrasive and deceptive personality along with xenophobic and reactionary policies (specific). We're motivated to criticize him because we care about our country, and we feel we should be led by a president who embodies great moral character and a more compassionate and inclusive vision of this nation. We feel that vision is consistent with our founding principles (even more specific) whereas those of Trump are not. Again, the last movement would actually appear to guide the criticism from the start. In any case they appear to be intertwined, as my 'cynicism mixed with romanticism' description was trying to convey. So yeah, I guess I'll double down here for the moment until I feel that criticism need not include any notion at all of privation or possible improvement.
The matter is this. Moral principles are very difficult to understand logically. Values must be grounded in ends. The end is what makes the value a "true" value, it is validated by the end. Ends must be clearly defined, or principles laid out whereby an end may be determined as good or bad, or else there are no true values whatsoever. You say "truthfulness is a value", but you do not support that logically, with reasons why truthfulness should be valued. Without these reasons, the claim is hollow. — Metaphysician Undercover
Okay, so truthfulness should be valued not as an end in itself, but because it contributes to the building up of trust and legitimacy in society, which in turn serve as the foundation for the ultimate end, which is social order and stability. Actually an even greater end would be the happiness of the individuals who make up that society. When trust is eroded through the use of lies by political leaders then legitimacy withers away, and when legitimacy is lacking then social stability is threatened. Without social stability then other ends, like economic prosperity, seem unattainable. If we start by positing individual freedom as the ultimate end or goal, then it would seem like something more akin to an anarchic 'state of nature' would be preferable, with an overemphasis on public security and stability threatening freedom and autonomy. Either way though I don't see how truth-telling could be disadvantageous to the social order. I'm sure you'll have plenty of counter-examples.
Now of course the likes of Plato and Machiavelli and Nietzsche (in other words men much smarter than myself) extolled the efficacy of lies and deception, and precisely in the name of order and stability. But even they felt there must at least be the appearance of truth. Why is that? Why the human proclivity against being lied to? I'm not sure. For me I feel it may have a lot to do with pride and ego. The fact that you lied to me makes me think you don't respect me, that you'd like to manipulate me for your own nefarious ends, etc. I recall the experience of my own enthusiastic patriotism giving way first to sadness and then to anger. I was lied to. I was ready to go join the military and possibly give my life for these noble ideals and lofty values I'd imbibed since childhood (through schooling, movies, etc.), and then to find out they were largely bullshit? That was a pretty devastating experience.
Anyhow I feel that much of the righteous indignation from those on the Left over Trump's habitual lying can be traced to the sense that he has zero respect for anything they value, and that he'll gladly lie in order to roll back any prior achievements won by progressives. So it's not his lying per se, but the aim of his lies which is the more important issue. Obviously those on the political Right (generally speaking) will rationalize away Trump's lies (
@Agustino), or, more likely, refuse to even acknowledge them as such. If the roles were reversed and Hillary were in office, then the situation would be the opposite--like the Tea Party's unrelenting attacks on Obama-- and we'd have one side failing to see lies as lies and the other seeing almost everything as a lie. Look where we're at with this right now. I don't think it's an exaggeration to say that violence and chaos are likely to come about more and more in coming weeks, months, years. There's a complete lack of trust, a sense that our government is illegitimate, and intimations of civil war sometime in the future as this nation hardens into two hostile camps with radically different worldviews.
So here is an example of criticism without an alternative proposal. I can criticise the mores of our society. I can say truth is becoming devalued. I can say that the entire moral structure, which was upheld in days long past, by the church, is becoming devalued. I can say that we take morality for granted, as if it is some naturally occurring thing, through the forces of evolution, and we've lost track of the fact that morality is really created artificially, requiring effort, strength of will. In our society we just assume that people will instinctively act morally, we have evolved to be like this. I have absolutely no idea or proposal for how to fix this. That's way beyond me. I can see a problem, and analyze it. And as I alluded to in the last passage, I can claim that it has to do with a loss of the philosophical mindset, but this is just deferring to a further problem. All I am doing here is working to identify the problem, similar to what Socrates did. I am providing no suggestions for resolution of the problem. — Metaphysician Undercover
Good points, but again, there seems to be an implicit understanding of an end (some general good) at work in the criticism. You want to fix the problem even if you're unable to. That desire for a better society--which is afflicted at the moment with rampant deception and the overall breakdown of morality--would appear to drive the criticism. The intuition that something's gone awry gives way to a diagnosis suggestive of possible solutions. Moral actions are good. Truthfulness is good. These are prerequisites of a stable society, in which other goods like freedom and the creation of wealth can thrive. You know, the old 'life, liberty and pursuit of happiness' themes which serve as this country's stated principles, and the securing of which is the
sine qua non of government. How about start being honest? And start behaving morally? Those would be possible solutions in light of the criticisms, and I'd imagine one could offer a pretty compelling argument as to why these would be conducive to the public (and individual) good, as understood and outlined in documents like the Declaration of Independence and the Constitution.
Regarding the example of Socrates, which I acknowledged to be a really good one (and still think so), well, even he seems intent upon bringing about some 'improved' condition in his interlocutors. He may not leave them with specific knowledge concerning things like justice, or love, or friendship, or even 'knowledge' itself, but at the very least they've been disabused of the notion that they know what they don't know. That could subsequently lead one to a state of humility characterized by an awareness of their ignorance, and this is vastly superior to an arrogance grounded in unwitting ignorance. This shift represents an improved condition of the soul, which has grown in wisdom if not in knowledge, and what could be more important than that? Clearly many feel the opposite is the case and that 'ignorance is bliss,' or some such, and that even the strongest, the most able, the most courageous among us conceal certain things from themselves out of necessity. Incidentally, this would translate well into a government's role in society being in part to shield citizens from unhelpful or even 'deadly' truths; I know many neocons inclined towards this opinion. It's definitely a timely topic right now in this 'post-truth' age.
