Agnosticism (Greek: α- a-, without + γνώσις gnōsis, knowledge; after Gnosticism) is the philosophical view that the truth value of certain claims — particularly metaphysical claims regarding theology, afterlife or the existence of God , gods, deities, ghosts or even ultimate reality — is unknown or, depending on the form of agnosticism, inherently impossible to prove or disprove.
Demographic research services normally list agnostics in the same category as atheists and non-religious people, using 'agnostic' in the sense of 'noncommittal'. However, this can be misleading given the existence of agnostic theists, who identify themselves as both agnostics in the original sense and followers of a particular religion.
Philosophers and thinkers who have written about agnosticism include Thomas Henry Huxley, Robert G. Ingersoll, and Bertrand Russell. Religious scholars who wrote about agnosticism are Peter Kreeft, Blaise Pascal and Joseph Ratzinger, later elected as Pope Benedict XVI.
"Agnostic" was introduced by Thomas Henry Huxley
in 1869 to describe his philosophy which rejects Gnosticism
, by which he meant not simply the early 1st millennium religious group, but all claims to spiritual or mystical knowledge.
Early Christian church leaders used the Greek word gnosis (knowledge) to describe "spiritual knowledge." Agnosticism is not to be confused with religious views opposing the doctrine of gnosis and Gnosticism—these are religious concepts that are not generally related to agnosticism. Huxley used the term in a broad sense.
In recent years, use of the word to mean "not knowable" is apparent in scientific literature in psychology and neuroscience, and with a meaning close to "independent", in technical and marketing literature, e.g. "platform agnostic" or "hardware agnostic".
Enlightenment philosopher David Hume
contended that meaningful statements about the universe are always qualified by some degree of doubt. The fallibility of human beings means that they cannot obtain absolute certainty except in trivial cases where a statement is true by definition (as in, "all bachelors are unmarried" or "all triangles have three angles"). All rational statements that assert a factual claim about the universe that begin "I believe that ...." are simply shorthand for, "Based on my knowledge, understanding, and interpretation of the prevailing evidence, I tentatively believe that...." For instance, when one says, "I believe that Lee Harvey Oswald
shot John F. Kennedy
," one is not asserting an absolute truth but a tentative belief based on interpretation of the assembled evidence. Even though one may set an alarm clock prior to the following day, believing that the sun will rise the next day, that belief is tentative, tempered by a small but finite degree of doubt (the sun might be destroyed; the earth might be shattered in collision with a rogue asteroid or that person might die before the alarm goes off.)
Many mainstream believers in the West embrace an agnostic stance. As noted below, for instance, Roman Catholic dogma about the nature of God contains many strictures of agnosticism. An agnostic who believes in God despairs of ever fully comprehending what it is in which he believes. But some believing agnostics assert that very absurdity strengthens their belief rather than weakens it.
The Catholic Church sees merit in examining what it calls Partial Agnosticism, specifically those systems that "do not aim at constructing a complete philosophy of the Unknowable, but at excluding special kinds of truth, notably religious, from the domain of knowledge. However, the Church is historically opposed to a full denial of the ability of human reason to know God. The Council of the Vatican, relying on biblical scripture, declares that "God, the beginning and end of all, can, by the natural light of human reason, be known with certainty from the works of creation" (Const. De Fide, II, De Rev.)
Types of agnosticism
Agnosticism can be subdivided into several subcategories. Recently suggested variations include:
- Strong agnosticism (also called "hard agnosticism," "closed agnosticism," "strict agnosticism," or "absolute agnosticism") refers the view that the question of the existence or nonexistence of God or gods and the nature of ultimate reality is unknowable by reason of our natural inability to verify any experience with anything but another subjective experience. A strong agnostic would say, "I don't know whether God exists or not, and neither do you."
- Weak agnosticism (also called soft agnosticism, open agnosticism, empirical agnosticism, temporal agnosticism)—the view that the existence or nonexistence of any deity is currently unknown but is not necessarily unknowable, therefore one will withhold judgment until/if more evidence is available. A weak agnostic would say, "I don't know whether God exists or not, but maybe you do."
- Apathetic agnosticism (also called Pragmatic agnosticism)—the view that there is no proof of either the existence or nonexistence of any deity, but since any deity that may exist appears unconcerned for the universe or the welfare of its inhabitants, the question is largely academic anyway.
- Agnostic theism (also called religious agnosticism)—the view of those who do not claim to know existence of any deity, but still believe in such an existence. (See Knowledge vs. Beliefs)
- Agnostic atheism—the view of those who do not know of the existence or nonexistence of a deity, and do not believe in any.
- Ignosticism—the view that a coherent definition of God must be put forward before the question of the existence of God can be meaningfully discussed. If the chosen definition isn't coherent, the ignostic holds the noncognitivist view that the existence of God is meaningless or empirically untestable. A.J. Ayer, Theodore Drange, and other philosophers see both atheism and agnosticism as incompatible with ignosticism on the grounds that atheism and agnosticism accept "God exists" as a meaningful proposition which can be argued for or against.
Famous agnostic thinkers
Among the most famous agnostics (in the original sense) have been Thomas Henry Huxley, Robert G. Ingersoll and Bertrand Russell.
Thomas Henry Huxley
Agnostic views are as old as philosophical skepticism, but the terms agnostic and agnosticism were created by Huxley to sum up his thoughts on contemporary developments of metaphysics about the "unconditioned" (Hamilton) and the "unknowable" (Herbert Spencer). It is important, therefore, to discover Huxley's own views on the matter. Though Huxley began to use the term "agnostic" in 1869, his opinions had taken shape some time before that date. In a letter of September 23, 1860, to Charles Kingsley, Huxley discussed his views extensively:
- I neither affirm nor deny the immortality of man. I see no reason for believing it, but, on the other hand, I have no means of disproving it. I have no a priori objections to the doctrine. No man who has to deal daily and hourly with nature can trouble himself about a priori difficulties. Give me such evidence as would justify me in believing in anything else, and I will believe that. Why should I not? It is not half so wonderful as the conservation of force or the indestructibility of matter...
- It is no use to talk to me of analogies and probabilities. I know what I mean when I say I believe in the law of the inverse squares, and I will not rest my life and my hopes upon weaker convictions...
- That my personality is the surest thing I know may be true. But the attempt to conceive what it is leads me into mere verbal subtleties. I have champed up all that chaff about the ego and the non-ego, noumena and phenomena, and all the rest of it, too often not to know that in attempting even to think of these questions, the human intellect flounders at once out of its depth.
And again, to the same correspondent, May 6, 1863:
- I have never had the least sympathy with the a priori reasons against orthodoxy, and I have by nature and disposition the greatest possible antipathy to all the atheistic and infidel school. Nevertheless I know that I am, in spite of myself, exactly what the Christian would call, and, so far as I can see, is justified in calling, atheist and infidel. I cannot see one shadow or tittle of evidence that the great unknown underlying the phenomenon of the universe stands to us in the relation of a Father [who] loves us and cares for us as Christianity asserts. So with regard to the other great Christian dogmas, immortality of soul and future state of rewards and punishments, what possible objection can I—who am compelled perforce to believe in the immortality of what we call Matter and Force, and in a very unmistakable present state of rewards and punishments for our deeds—have to these doctrines? Give me a scintilla of evidence, and I am ready to jump at them.
Of the origin of the name agnostic to describe this attitude, Huxley gave the following account:
- When I reached intellectual maturity and began to ask myself whether I was an atheist, a theist, or a pantheist; a materialist or an idealist; Christian or a freethinker; I found that the more I learned and reflected, the less ready was the answer; until, at last, I came to the conclusion that I had neither art nor part with any of these denominations, except the last. The one thing in which most of these good people were agreed was the one thing in which I differed from them. They were quite sure they had attained a certain "gnosis,"–had, more or less successfully, solved the problem of existence; while I was quite sure I had not, and had a pretty strong conviction that the problem was insoluble.
- So I took thought, and invented what I conceived to be the appropriate title of "agnostic." It came into my head as suggestively antithetic to the "gnostic" of Church history, who professed to know so much about the very things of which I was ignorant. To my great satisfaction the term took.
Huxley's agnosticism is believed to be a natural consequence of the intellectual and philosophical conditions of the 1860s, when clerical intolerance was trying to suppress scientific discoveries which appeared to clash with a literal reading of the Book of Genesis and other established Jewish and Christian doctrines. Agnosticism should not, however, be confused with natural theology, deism, pantheism, or other science positive forms of theism.
By way of clarification, Huxley states, "In matters of the intellect, follow your reason as far as it will take you, without regard to any other consideration. And negatively: In matters of the intellect, do not pretend that conclusions are certain which are not demonstrated or demonstrable" (Huxley, Agnosticism, 1889). While A. W. Momerie has noted that this is nothing but a definition of honesty, Huxley's usual definition goes beyond mere honesty to insist that these metaphysical issues are fundamentally unknowable.
Robert G. Ingersoll
Robert G. Ingersoll, an Illinois lawyer and politician who evolved into a well-known and sought-after orator in 19th century America, has been referred to as the "Great Agnostic."
In an 1896 lecture titled Why I Am An Agnostic, Ingersoll related why he was an agnostic:
- Is there a supernatural power—an arbitrary mind—an enthroned God—a supreme will that sways the tides and currents of the world—to which all causes bow? I do not deny. I do not know—but I do not believe. I believe that the natural is supreme—that from the infinite chain no link can be lost or broken—that there is no supernatural power that can answer prayer—no power that worship can persuade or change—no power that cares for man.
- I believe that with infinite arms Nature embraces the all—that there is no interference—no chance—that behind every event are the necessary and countless causes, and that beyond every event will be and must be the necessary and countless effects.
- Is there a God? I do not know. Is man immortal? I do not know. One thing I do know, and that is, that neither hope, nor fear, belief, nor denial, can change the fact. It is as it is, and it will be as it must be.
In the conclusion of the speech he simply sums up the agnostic position as:
- We can be as honest as we are ignorant. If we are, when asked what is beyond the horizon of the known, we must say that we do not know.
Bertrand Russell's pamphlet, Why I Am Not a Christian, based on a speech delivered in 1927 and later included in a book of the same title, is considered a classic statement of agnosticism. The essay briefly lays out Russell’s objections to some of the arguments for the existence of God before discussing his moral objections to Christian teachings. He then calls upon his readers to "stand on their own two feet and look fair and square at the world," with a "fearless attitude and a free intelligence."
In 1939, Russell gave a lecture on The existence and nature of God, in which he characterized himself as an agnostic. He said:
- The existence and nature of God is a subject of which I can discuss only half. If one arrives at a negative conclusion concerning the first part of the question, the second part of the question does not arise; and my position, as you may have gathered, is a negative one on this matter.
However, later in the same lecture, discussing modern non-anthropomorphic concepts of God, Russell states:
- That sort of God is, I think, not one that can actually be disproved, as I think the omnipotent and benevolent creator can.
In Russell's 1947 pamphlet, Am I An Atheist Or An Agnostic? (subtitled A Plea For Tolerance In The Face Of New Dogmas), he ruminates on the problem of what to call himself:
- As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic, because I do not think that there is a conclusive argument by which one can prove that there is not a God.
- On the other hand, if I am to convey the right impression to the ordinary man in the street I think I ought to say that I am an Atheist, because when I say that I cannot prove that there is not a God, I ought to add equally that I cannot prove that there are not the Homeric gods.
In his 1953 essay, What Is An Agnostic? Russell states:
- An agnostic thinks it impossible to know the truth in matters such as God and the future life with which Christianity and other religions are concerned. Or, if not impossible, at least impossible at the present time.
However, later in the essay, Russell says:
- I think that if I heard a voice from the sky predicting all that was going to happen to me during the next twenty-four hours, including events that would have seemed highly improbable, and if all these events then produced to happen, I might perhaps be convinced at least of the existence of some superhuman intelligence.
Religious scholars, whether Jewish, Muslim or Christian, affirm the possibility of knowledge, even of metaphysical realities such as God and the soul, because human intelligence ("intus", within and "legere", to read) has the power to reach the essence and existence of things since it has a non-material, spiritual element. They affirm that “not being able to see or hold some specific thing does not necessarily negate its existence,” as in the case of gravity, entropy, mental telepathy, or reason and thought.
According to these scholars, agnosticism is impossible in actual practice, since one either lives as if God did not exist (etsi Deus non daretur), or lives as if God did exist (etsi Deus daretur). These scholars believe that each day in a person’s life is an unavoidable step towards death, and thus not to decide for or against God, the all-encompassing foundation, purpose, meaning of life, is to decide in favor of atheism. Even if there were truly no evidence for God, Christian philosopher Blaise Pascal offered to agnostics what is known as Pascal’s Wager: the infinite expected value of acknowledging God is always greater than the expected value of not acknowledging his existence, and thus it is a safer “bet” to choose God.
These religious scholars argue that God has placed in his creation much evidence of his existence, and continues to personally speak to humans. Peter Kreeft and Ronald Tacelli write about a strong, cumulative case with their 20 rational arguments for God’s existence. And, these scholars state, when agnostics demand from God that he proves his existence through laboratory testing, they are asking God, a superior being, to become man’s servant.
According to Joseph Ratzinger later elected as Pope Benedict XVI, agnosticism, more specifically strong agnosticism, is a self-limitation of reason that contradicts itself when it acclaims the power of science to know the truth. When reason imposes limits on itself on matters of religion and ethics, this leads to dangerous pathologies of religion and pathologies of science, such as destruction of humans and ecological disasters. "Agnosticism," said Ratzinger, "is always the fruit of a refusal of that knowledge which is in fact offered to man... The knowledge of God has always existed." Agnosticism, stated Ratzinger, is a choice of comfort, pride, dominion, and utility over truth, and is opposed by the following attitudes: the keenest self-criticism, humble listening to the whole of existence, the persistent patience and self-correction of the scientific method, and a readiness to be purified by the truth.
