We must not confuse dissent with disloyalty. When the loyal opposition dies, I think the soul of America dies with it.

The politician in my country seeks votes, affection and respect, in that order. With few notable exceptions, they are simply men who want to be loved.

Most truths are so naked that people feel sorry for them and cover them up, at least a little bit.

Just because your voice reaches halfway around the world doesn't mean you are wiser than when it reached only to the end of the bar.

Is is worth considering the strange media landscape in which political talk radio is a salient. Never before have there been so many different national news sources — different now in terms of both medium and ideology. Major newspapers from anywhere are available online; there are the broadcast networks plus public TV, cable's CNN, Fox News, CNBC, et al., print and Web magazines, Internet bulletin boards, The Daily Show, e-mail newsletters, blogs. All this is well known; it's part of the Media Environment we live in. But there are prices and ironies here. One is that the increasing control of U.S. mass media by a mere handful of corporations has — rather counterintuitively — created a situation of extreme fragmentation, a kaleidoscope of information options. Another is that the ever increasing number of ideological news outlets creates precisely the kind of relativism that cultural conservatives decry, a kind of epistemic free-for-all in which "the truth" is wholly a matter of perspective and agenda. In some respects all this variety is probably good, productive of difference and dialogue and so on. But it can also be confusing and stressful for the average citizen. Short of signing on to a particular mass ideology and patronizing only those partisan news sources that ratify what you want to believe, it is increasingly hard to determine which sources to pay attention to and how exactly to distinguish real information from spin.

A little learning is a dangerous thing. This has never struck me as a particularly profound or wise remark, but it comes into its own when that little learning is in philosophy. A scientist who has the temerity to utter the t-word — true — is likely to encounter philosophical heckling that goes something like this: "There is no absolute truth. You are committing an act of personal faith when you claim that the scientific method, including mathematics and logic, is the privileged road to truth. Other cultures might believe that truth is to be found in a rabbit's entrails or the ravings of a prophet atop a pole. It is only your personal faith in science that leads you to favor your brand of truth." That strand of half-baked philosophy goes by the name of cultural relativism.

How should scientists respond to the allegation that our "faith" in logic and scientific truth is just that — faith — not "privileged" over alternative truths? An obvious response is that science gets results. As I once wrote, "Show me a cultural relativist at 30,000 feet, and I'll show you a hypocrite... If you are flying to an international congress of anthropologists or literary critics, the reason you will probably get there — the reason you don't plummet into a ploughed field — is that a lot of Western scientifically trained engineers have got their sums right." Science supports its claim to truth by its spectacular ability to make matter and energy jump through hoops, and to predict what will happen and when.

It is simply true that the sun is hotter than the earth, true that the desk on which I am writing is made of wood. These are not hypotheses awaiting falsification, not temporary approximations of an ever elusive truth, not local truths that might be denied in another culture. They are just plain true. It is forever true that DNA is a double helix, true that if you and a chimpanzee (or an octopus or a kangaroo) trace your ancestors back far enough, you will eventually hit a shared ancestor.

[I]s this posture in fact possible for a human being: can a person accept it, and accept it authentically, without bad faith or doublethink? I am to remain a Christian, to take part in Christian worship, to accept the splendid and powerful doctrines of traditional Christianity. However, I am also to take it that these doctrines are only mythologically true: they are literally false, although accepting them (i.e., accepting them as true, as literally true) puts or tends to put one into the right relation with the Real. And how can I possibly accept them, adopt that attitude toward them, if I think they are only mythologically true — that is, really false? I could, indeed, believe that they are mythologically true; believing that, however, doesn't move one toward the right kind of life; it is only believing the teachings themselves that allegedly has that salutary effect. Once I am sufficiently enlightened, once I see that those doctrines are not true, I can no longer take the stance with respect to them that leads to the hoped-for practical result. I am left, instead, in the position of a sad and disillusioned Gnostic. I no longer hold Christian belief; I recognize, as I think, that it is in fact false. I also see, of course, that those who do accept it as true are mistaken, deluded; but at any rate they are in the fortunate position of enjoying the comfort and strength and consolation these false beliefs bring; they are also being moved closer to the right kind of life.

This has given rise to different forms of agnosticism and relativism which have led philosophical research to lose its way in the shifting sands of widespread scepticism. Recent times have seen the rise to prominence of various doctrines which tend to devalue even the truths which had been judged certain. A legitimate plurality of positions has yielded to an undifferentiated pluralism, based upon the assumption that all positions are equally valid, which is one of today's most widespread symptoms of the lack of confidence in truth. Even certain conceptions of life coming from the East betray this lack of confidence, denying truth its exclusive character and assuming that truth reveals itself equally in different doctrines, even if they contradict one another. On this understanding, everything is reduced to opinion; and there is a sense of being adrift. While, on the one hand, philosophical thinking has succeeded in coming closer to the reality of human life and its forms of expression, it has also tended to pursue issues—existential, hermeneutical or linguistic—which ignore the radical question of the truth about personal existence, about being and about God. Hence we see among the men and women of our time, and not just in some philosophers, attitudes of widespread distrust of the human being's great capacity for knowledge. With a false modesty, people rest content with partial and provisional truths, no longer seeking to ask radical questions about the meaning and ultimate foundation of human, personal and social existence. In short, the hope that philosophy might be able to provide definitive answers to these questions has dwindled.
