Influence of logical positivism

Perhaps the largest body of work, however, was generated in dialogue with the linguistic turn of philosophy in the English-speaking world, concentrating on the analysis of language in its various uses. The logical positivist movement originated in the 1920s with the Vienna Circle. Although mainly concerned with the philosophy of science, it posed by implication a major challenge to the logical meaningfulness of religious language. The positivist position, in its developed form, was that a statement has factual meaning only if it is capable in principle of being verified or falsified, or at least in some degree confirmed or disconfirmed, within human experience; otherwise it is meaningless, or cognitively vacuous. In the years immediately after World War II this account of factual meaning was applied (e.g., by Antony Flew) to theological statements, raising such questions as: What observable difference does it make whether it is true or false that “God loves us”? Whatever tragedies occur, do not the faithful still maintain their belief, adding perhaps that the divine love is beyond human comprehension? But if it is not possible to conceive of circumstances in which “God loves us” would have to be judged false, is not the statement factually empty, or meaningless?

This challenge evoked three kinds of response. Some Christian philosophers declared it to be a nonchallenge, on the ground that the positivists never succeeded in finding a precise formulation of the verification criterion that was fully satisfactory even to themselves. Others held that this does not block the central thrust of the positivist challenge. Does it really make no difference within actual or possible human experience whether or not God exists and loves us; and if so, is not the significance of the belief thereby fatally damaged? Among those who felt it necessary to face this challenge, one group granted that theological statements lack factual meaning and suggested that their proper use lies elsewhere, as expressing a way of looking at the world (e.g., Richard M. Hare) or a moral point of view and commitment (e.g., R.B. Braithwaite). The other group claimed that theism is ultimately open to experiential confirmation. The theory of eschatological verification (developed by John Hick) holds that the belief in future postmortem experiences will be verified if true (though not falsified if false), and that in a divinely governed universe such experiences will take forms confirming theistic faith. Thus although the believer and the disbeliever do not have different expectations about the course of earthly history, they do expect the total course of the universe to be radically different.

In the late 20th century, under the stimulus of Wittgenstein’s posthumously published works, attention was directed to the multiple legitimate uses of language in the various language games developed within different human activities and forms of life; and it was suggested that religious belief has its own autonomous validity, not subject to verificationist or scientific or other extraneous criteria. Statements about God and eternal life do not make true-or-false factual claims but express, in religious language, a distinctive attitude to life and way of engaging in it. This suggestion formed part of the broader non-realist interpretation of religion, which held that religious beliefs do not refer to putative transcendent realities but are instead expressive of human ideals, desires, hopes, attitudes, and intentions. Such thinking goes back to the German philosopher Ludwig Feuerbach (The Essence of Christianity, 1841) in the 19th century. It was promoted in the early 20th century by George Santayana, John Dewey, and J.H. Randall, Jr., and later by Christian writers such as D.Z. Phillips and Don Cupitt. According to them, true Christianity consists in the inner purity of an unself-centred attitude to life and does not involve belief in the objective reality of God or of a life after death. This view, however, was criticized on the grounds that to deny the transcendent reference of religious language empties it of any substantial meaning.
