Among the various ways of responding to an idea, the following three ways deserve explicit discussion. For want of better terms, I will call them the aesthetic, the ethical, and the philosophical. If the terminology reminds you of the aesthetic, ethical, and religious stages in Kierkegaard, there is some analogy. I am using 'idea' in roughly the way it is used in 'history of ideas.' An example of an idea in this sense is the ethical doctrine of hedonism according to which pleasure is always good for its own sake, and is the only thing that is good for its own sake.
1. The Aesthetic Response. The aesthete responds to ideas subjectively.
Examples of aesthetic responses:
I can't relate to what you are saying.
I like what you are saying.
There is nothing new in that idea.
That's not what I was brought up to believe.
Many would find what you are saying offensive.
An exchange between Ann Coulter and Donny Deutsch is a recent example. Coulter said in effect that according to Christian doctrine, Judaism needs to be perfected, and Deutsch responded by labelling Coulter's statement "hateful."
Instead of responding to the objective content of Coulter's remark, which can in no way be construed as hateful since it merely records a fact about Christian doctrine, Deutsch reported on the feelings elicited in him by Coulter's statement. His response was subjective, and to that extent 'aesthetic.'
Aestheticism manifests itself in one's fixating on the idea's expression, whether the fact of its being expressed, or the form in which it is expressed, while ignoring its content. The aesthete is typically concerned less with what is said than how it is said or why it is said. The aesthete is not concerned with whether the idea is true or false, nor is he concerned to inquire into its exact meaning. He 'knows' what is being said, and bypassing the question of its truth or falsity, attends to whether he finds it congenial, 'empowering,' offensive, 'creative,' 'original,' attractive, 'what people are saying,' and the like.
2. The Ethical Response. To approach an idea ethically is to treat it with the respect it deserves, as embodying a truth-claim. This is precisely what the aesthete does not do. He doesn't ask, 'Is it true?' Fundamentally unserious, he doesn't care whether it is true. This is what makes him an aesthete. He cares how it strikes him, how it makes him feel; not whether it comports well with reality. Reality? That's just another idea for the aesthete to play with. And play with it he does. 'Reality's an illusion,' he quips and thinks himself clever as he heads for the blogosphere.
Just as it is unethical, as Kant insisted, to treat human beings as mere means, rather than as ends in themselves, it is arguably a violation of the ethics of belief to ignore an idea's truth-claim and reality-reference and to treat it as a mere means to one's enjoyment or the opposite.
To explore the cartography of the mind is one of the delights of the life of the mind. Ideas are fascinating in their wild diversity, in their logical interconnection, in their historical development. But to study them for their own sake as mere cultural facts is to remain on the level of the uncommitted and immature, much like the young person who samples the wide variety offered by the opposite sex without committing himself to one person. His concern is not to find the right person (or a right person) in order t commit himself to her; his concern is to find any person who flatters him, is a source of pleasure, would make a useful social appendage, etc.
The'ethical' adventurer among ideas seeks the true ones in order to commit himself to them. The 'aesthete' remains a mere sampler at the smorgasbord of intellectual delights. Among the delights he finds, of course, are ethical doctrines which he enjoys in their wild diversity, logical interconnection, and historical development — but without doing anything so rash as to choose one and live in accordance with it.
3. The Philosophical Response. You will have guessed that this must be the highest and best response, and indeed it it is. The 'ethicist' seeks truth and commits himself to the truth he thinks he has found. That is good as far as it goes. It is surely better than the modus vivendi of the 'playboy of ideas,' the intellectual aesthete. The philosopher, like the 'ethicist'(ethete?), seeks truth, but unlike the 'ethicist' he is wary of premature commitment, well aware that, though it is good to commit oneself to what one takes to be the truth, one must be sure that it really is the truth. It is better, perhaps, to make no commitments than to make the wrong commitments. (Think of all the brilliant and morally outstanding young people in the 20th century who wasted all or parts of their lives on the pernicious illusions of Communism. It would arguably have been better had they remained ordinary livers of the private life.)
To prosecute the inquiry into truth, the philosopher must inquire into what the idea in question means. The philosopher questions the very meaning of ideas, which involves him in a set of questions logically prior to the question of the idea's truth or falsity. The philosopher practises a certain ascesis, a certain detachment. He detaches himself from the idea's aesthetic features (the elegance of its expression, the feelings it evokes, the 'neighborhood' it resides in and all such extraneous matters) but he also detaches himself, provisionally, from the question of the idea's truth, not because he is not interested in the truth but precisely because he is interested in the truth in excelsis and not in what is merely taken to be truth. For before he can tackle the question of truth of an idea, the philosopher must understand what the idea means. His question is not primarily whether what is being said is true, but: what is being said? One might schematize the matter as follows:
Intellectual Aesthete: Is the idea pleasing, 'empowering,' interesting, etc.?
Intellectual 'ethicist': Is the idea true, and thus worthy of my commitment?
Philosopher: Is the idea meaningful, and what does it mean?
To illustrate, suppose the idea is that 'Pleasure is the good.' The aesthete asks himself whether he likes this idea. His concern is with how he feels in the presence of this idea, not with either its objective content or it truth-value. The 'ethicist' would know whether it is true that the good is pleasure. The philosopher, however, realizes that it is pointless to debate whether the good is pleasure without preliminary clarification of what is meant by 'good' and by 'pleasure.' And similarly through a vast range of issues. It makes no sense to debate whether waterboarding is torture without a preliminary, detailed, inquiry into what torture is. Absent such preliminary inquiry one may be treated to the idiotic spectacle of two politicians in debate, neither willing to endorse torture as a tool of interrogation, frightened of the very word, and yet one of them committed to it by others of his assertions, but neither of them having any clear idea of what they are talking about.
The ordinary person has no patience with any of this, thinking that he knows quite well what he means by the words he bandies about, words like 'democracy,' and 'justice,' and 'religion.' That is why he needs philosophy which, in its Socratic essence, is an exposure of the ignorance hiding behind pretended knowledge.
