The claim that science is a religion is clung to with imbecilic desperation. The claimant hopes to besmirch science; for science is no respecter of bollix, and thus it makes many enemies. At first sight, one might think that the claimant would be embarrassed and shamed by so bold a display of his intellectual shortcomings. But it must be borne in mind that the claim is most often uttered not in thoughtful reflection, but rather in a zealous attempt to suggest that science is no better than a religion, the implication being that, like religion, it relies on faith, and that its assertions are no more founded than those of, say, Shinto or Christianity or Islam. Now, before I go any further, what I attack here is not religion or faith, but rather the deliberate conflating of these with science and knowledge.
.....It must be said that the claim that science is a religion rarely comes from theistic religionists, but rather from left- and right-wing political and ideological extremists, whose presence is common enough, unfortunately, for them to avoid the label extremist. The claim is attractive to them because, if scientific knowledge is just another faith, then it has no bearing on their own particular political or ideological faiths – that is, they can continue to maintain their beliefs in the face of contradictory knowledge.
.....The claim hinges on the question of faith. Science reasons from basic assumptions, the so-called faiths of science:
1) Things exist; the world is real
2) Things are knowable; the world is knowable
3) There are laws that govern the world
4) These laws are knowable
5) It is possible to reason about things, and to make rational inferences from the observed to the unobserved.
.....Science makes these assumptions, the same assumptions that you make if you wish to survive in the world, ones which help you to boil an egg, catch a bus, not walk off cliffs, avoid pain, or find your pen to write nonsensical treatises on the unknowability of things, assumptions so basic that they are necessary for life. Call these assumptions facets of faith if you wish, but you make a mockery of words as well as of yourself; for if one wishes to maintain the humbug that the world of knowable objects and laws is a faith, then one ought to reflect that we are first bound to this not by science but by the necessity of living; and if these things are faiths, then living itself is a religion to which we are bound thereby; and if one calls living a religion, what cannot be called a religion?
.....It takes only a cursory glance at science and religion to discover that they are very different indeed. The realist assumptions of science—to which we are all sincerely committed—provide the grounds from which all knowledge is derived. The process of science thereafter is one of building knowledge and theories that are established or tested by observation and reason. Scientific theories stand or fall by the evidence. Science says no more about the world than can be observed and reasoned about it. This cannot be said for religion, however. Religion is based on other assumptions that go beyond the mundane. Consider the following:
God is the Father, the Son, and the Holy Ghost (Christianity)
There is no God but Allah and his prophet is Mohammed (Islam)
Kami Izanagi and kami Izanami created the world and its elements (Shinto)
Now, it would be remiss of me to suggest that science is not a religion because it does not make any of these particular claims. Science claims none of these things, that is for sure, but what sets it apart is that it cannot claim anything like them; for it cannot postulate what is unobservable and untestable—its very ethos is one of observing the world and testing its theories against it. A religion, on the other hand, has as its foundation something more: some inexplicable and inscrutable power at work behind or beyond or above the world, one which is unobservable and untestable, constituting a faith that is preserved as sacred against, indifferent, or unanswerable to observation. Now, for all I know, one of the religious propositions given above is true, though I doubt each of them, the point being that each requires faith in order that one believe them to be true.
.....I wish to coin a new word, not gratuitously I trust you’ll find:
overstand, vt. To subordinate sense and reason to faith; not to understand the world, but rather to interpret the world through faith in something higher, greater, ‘more real-worldly’ than the world; to interpret according to faith and not evidence; to believe that something is the case irrespective of evidence; to make facts subordinate to an inscrutable purpose and an ineffable standard.
Science is an attempt to understand the world; religion, an attempt to overstand it. The world takes primacy in science. Under religion, however, the world is interpreted in an unworldly way—that is, there is something more, something higher, a purpose, a spirit, something beyond the mundane. As such, it can deny the world its primacy: the world is something lesser, a pale shadow of something greater. This primacy of unworldliness explains why the belief in something beyond the world can take precedence over anything in it: facts may be denied because they contradict the belief in the higher power or purpose. This is no less true with what are sometimes called “secular religions”. In Marxism, for instance, the world is subject to an historical inevitability, an ineffable purposive force that guides humankind to its predestined, communistic end. Nevertheless, there is a perfectly good word which is aptly redolent of the stench of such things: ideology.
.....In conclusion, I return to what was expressed at the beginning: that the real reason why miscreants call science a religion is not because they think calling it so helps us to understand what science is, but on the contrary, because they hope the confusion of the one with the other will suggest a parity of justification in beliefs, and in so doing, help protect their own politically, religiously, or ideologically inspired beliefs from the knowledge which the process of science affords us. The failure to distinguish between science and religion has no merit except to expose the meritless nature of him who fails to distinguish between them.
