Is the monologue also a dialogue?

No, taught Martin Buber, since a monologue lacks the dimension of Otherness. He was so adamant about that, that he even applied it to the case of God. Maurice Friedman (Martin Buber. The Life of Dialogue, p. 82) describes the relation of God and each single human being as follows:

If God did not need man, if man were simply dependant and nothing else, there would be no meaning to man’s life or to the world. ‘The world is not divine sport, it is divine destiny’.

Martin Buber’s own words (I and Thou, p. 82) are even more direct:

You know always in your heart that you need God more than everything; but do you not know too that God needs you—in the fullness of His eternity needs you? […] You need God, in order to be—and God needs you, for the very meaning of life.

Somehow, I am not surprised that Maurice Friedman participated in one of Daya Krishna’s saṃvādas (one can read the transcripts in Intercultural Dialogue and the Human image, Maurice Friedman at Indira Gandhi National Centre for the Arts.

Daya Krishna on the risks of comparatism

‘Comparative studies’, thus, meant in effect the comparison of all other societies and cultures in terms of the standards provided by the Western societies and cultures, both in cognitive and non cognitive domains. The scholars belonging to these other societies and cultures, instead of looking at Western society and culture from their own perspectives, accepted the norms provided by Western scholars and tried to show that the achievements in various fields within their cultures paralleled those in the West”.
