self-refuting statements: a proud tradition

From the standpoint of logic, some statements are unusual. For instance, a statement could assert its own truth: "I tell the truth." It could be redundant: "The obvious statement is obvious." It could reference itself: "I have seven syllables."

Yet self-refuting statements are the most unusual specimens of all. "I am lying" is the prototype, but unfortunately it is far from alone. In fact, generations of humans have believed in clusters of these.
  • My benevolent god wishes that I kill you.
  • My omnipotent god requires me to defend it.
  • The freedom my god has granted to me is expressed through complete and unquestioning obedience to specific forms of coercion.
  • Sacred statements possess objective Truth because of the opinions of many believers, referred to as 'faith'.
  • Centuries-old moral customs last eternally as long as believers expertly modify the original formulations, in order to integrate the many deep cultural changes which happened since.
  • Centuries-old texts are literally true and readily apparent apart from the sections which are purely metaphorical and infinitely debatable.
  • Divine justice shall come, although that may not occur until after every good believer is already dead.
  • My god is affected by the requests of earnest believers, but it does whatever it wishes regardless.
  • After altering my internal state of mind via various techniques, I eventually sense the external existence of the spiritual realm.
  • The best 'open-minded' way to fairly check for god's existence is to greatly discount contrary signals and greatly magnify agreeable signals, i.e. you must believe in order to see.
  • I construe the truism "absence of proof is not proof of absence" as affirmation of my views alone, despite placing my views in the same logical category as every unobserved "thing", including the irritating gnomes that steal socks on laundry day.
I have no doubt that thoughtful believers have their own thorough responses to the preceding statements. In return they may feel inspired to suggest self-refuting statements to illustrate my beliefs. I'll anticipate a few on their behalf, and then counter each one immediately (blogger's privilege):
  • Transcendent authority doesn't exist, but that doesn't stop me from claiming to know truths better than you. Authority and correctness don't need to be transcendent to be pragmatically useful. Beliefs lie on a continuum of certainty based on the level of verification of the beliefs' implications. Depending on the particular belief, I am simply too unimpressed by the belief itself or its inadequate verification.
  • My skepticism of others' fundamental axioms overlooks the unavoidable necessity of my own. I don't dispute the necessity of minimal axioms. Something must function as the foundation of symbolic thought. However, that doesn't justify an explosion of mostly-unproven assumptions about the universe. Better to have few axioms than many axioms.
  • Like all humans, I opine that some morality is superior to the rest, although my failure to profess transcendence once again presents no plausible basis for me to do so. Ethical principles and guidelines can originate from humanity. So can goals and ideals ("values"). Instead of reference to an ultimate moral standard, I use the full extent of my human capabilities to perceive and balance the various concerns which apply to a dilemma. When asked, I explain my analysis and justifications bit by bit without mentioning any gods whatsoever, because the backing of a god is irrelevant to evaluating the righteousness of my moral judgment. The religious actually agree on this point. During a conflict between differing religions 1 and 2, the proponents of religion 1 certainly don't give any more credence to the conflicting morals of religion 2 due merely to the ("false") god of religion 2...
  • Imperceptible inferences about the supernatural domain are inexcusable, while imperceptible inferences about the natural domain are customary. Inferences differ in validity and probability. To infer the supernatural is to step far beyond the support of known reliable facts. Satisfactory proof needs to be consistent and therefore statistically significant (i.e. not explicable by the slim nonzero chance of rare coincidences). Inferences of supernatural causes fail the criteria, at least in comparison to competing inferences of natural causes. Supernatural causes also have the downsides of extravagant mystery and unpredictability. Placing blame on undetectable mind-organisms, like unidentified designers, raises a torrent of aggravating questions about life-cycle, psychology, habitat, composition...
  • Reason and decision-making have resulted in the inescapable conclusion that 'reason' and 'decision-making' are illusions superimposed on the brain's physics of matter and energy. I suppose, but according to that logic, isn't everything "illusions" superimposed on physics of matter or energy? Surely reason and decision-making can continue to be meaningful if the innards of the two are particles rather than ghostly mind-stuff. In either case, marvelous symbolic computations continue to yield stunning products. Matter can be the executor and storage of the computations, assuming the right configuration: not tiny isolated chunks of it, like hydrogen gas, but vast populations and multitudes of interconnections, like BRAINSSSS.
  • Humans are content with an existence in an unguided universe which contains no god(s) and no afterlife. The flippant rejoinder is that human contentment isn't the aim, truths are; the appropriate reactions to the truths are "left as an exercise" to the seekers. Seriously, my recommendation is to avoid obsession on unchangeable Big Questions. Such obsessions are distractions from what can be enjoyed and controlled: daily life, on planet Earth, in the 21st century. On the other hand, I think it's generally good for a human to create a "purpose" and to acknowledge/accept the danger of inevitable death. For example, motivation for rectifying some of the terrible afflictions on humanity, even on a small scale, isn't contingent on how much it pleases gods.
