A child in the sixth grade in a Sunday School in New York City, with the encouragement of her teacher, wrote to Einstein in Princeton on 19 January 1936 asking him whether scientists pray, and if so what they pray for. Einstein replied as follows on 24 January 1936;
Scientific research is based on the idea that everything that takes place is determinedby laws of nature, and therefore this holds for the actions of people. For this reason, a research scientist will hardly be inclined to believe that events could be influenced by a prayer, i.e. by a wish addressed to a supernatural Being.
However, it must be admitted that our actual knowledge of these lawas is only imperfect and fragmentary, so that, actually, the belief in the existenve of basic all-embracing laws in Nature also rests on a sort of faith. All the same this faith has been largely justified so far by the success of scientific research.
But, on the other hand, every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe -- a spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble. In this way the pursuit of science leads to a religious feeling of a special sort, which is indeed quite different from the religiousity of someone more naive.
It is worth mentioning that this letter was written a decade after the advent of Heisenberg's principl of indeterminacy and the probablistic interpretation of quantum mechanics with its denial of strict determinism.
What I see in Nature is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of "humility". This is a genuinely religious feeling that has nothing to do with mysticism.
In responding to this poignant cry for help, Einstein offered no easy solace, and this very fact must have heartened the student and lightened the lonely burden of his doubts. Here is Einstein's response. It was written in English and sent from Princeton on 3 December 1950, within days of receiving the letter.
If you ask for the purpose or goal of society as a whole or of an individual taken as a whole the question loses its meaning. This is, of course, even more so if you ask the purpose of meaning of nature in general. For in those cases it seems quite arbitrary if not unreasonable to assume somebody whose desires are connected with the happenings.
Nevertheless we all feel that it is indeed very reasonable and important to ask ourselves how we should try to conduct our lives. The answer is, in my opinion: satisfaction of the desires and needs of us all, as far as this can be achieved, and achievement of harmony and beauty in the human relationships. This presupposes a good deal of conscious thought and of self-education. It is undeniable that the enlightened Greeks and the old Oriental sages had achieved a higher level in this all-important field that what is alive in our schools and universities.
On 17 July 1953 a woman who was a licensed Baptist pastor sent Einstein in Primceton a warmly appreciative evangelical letter. Quoting several passages from the scriptures, she asked him whether he had considered the relationship of his immortal soul to its Creator, and asked whether he felt assurance of ever lasting life with God after death. It is not known whether a reply was sent, but the letter is in the Einstein Archives, and on it, in Einstein's handwriting, is the following sentence, written in English:
From p. 40
In Berlin in February 1921 Einstein received from a woman in Vienna a letter imploring him to tell her if he had formed an opinion as to whether the soul exists and with it personal, individual developement after death. There were other questions of a similar sort. On 5 February 1921 Einstein answered at some length. Here in part is what he said:
Since our inner experiences consist of reproductions and combinations of sensory impressions, the concept of a soul without a body seems to me to be empty and devoid of meaning.
On 24 March 1954 Einstein answered in English as follows:
It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not beleive in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.
I have no possibility to bring the money you sent me to the appropriate receiver. I return it therefore in recognition of your good heart and intention. Your letter shows me also that wisdom is not a product of schooling but of the lifelong attempt to acquire it.
From p. 66
There is in the Einstein Archives a letter dated 5 August 1927 from a banker in Colorado to Einstein in Berlin. Since it begins "Several months ago I wrote you as follows," one may assume that Einstein had not yet answered. The banker remarked that most scientists and the like had given up the idea of God as a bearded, benevolent father figure surrounded by angels, although many sincere people worship and revere such a God. The question of God has arisen in the course of a discussion in a literary group, and some of the members decided to ask eminent men to send their views in a form that would be suitable for publication. He added that some twenty-four Nobel Prize winners had already responded, and he hoped that Einstein would too. On the letter, Einstein wrote the following in German, It may or may not have been sent:
My religiousity consists in a humble admiration of the infinitely superior spirit that reveals itself in the little that we, with our weak and transitory understanding, can comprehend of reality. Morality is of the highest importance-but for us, not for God.
From pp. 69-70
A Chicago Rabbi, preparing a lecture on "The Religious Implications of the Theory of Relativity," wrote to Einstein in Princeton on 20 December 1939 to ask some questions on the topic. Einstein replied as follows:
The religious feeling engendered by experiencing the logical comprehensibility of profound interrelations is of a somewhat different sort from the feeling that one usually calls religious. It is more a feeling of awe at the scheme that is manifested in the material universe. It does not lead us to take the step of fashioning a god-like being in our own image-a personage who makes demands of us and who takes an interest in us as individuals. There is in this neither a will nor a goal, nor a must, but only sheer being. For this reason, people of our type see in morality a purely human matter, albeit the most important in the human sphere.
