"I and Thou" by Martin Buber,1923

..
There is no independent "I" but only the I existing and known in objective relation to something other than itself,an "It",or as encountered by encompassed by other,the "Thou".
.
Just as music can be studied analytically by reference to its notes,verses,and bars,
or encountered and experienced in such a manner that it is known not by its parts but as a unity,so the I can relate itself analytically to something other,"It",
or it can encountered the other,"Thou",so as to form a living unity.
.
The "Thou" stands as judge over "It",
but as a judge with the form and creative power for the transformation of "It".
.
Each encountered "Thou" reveals the nature of all reality,
but finally the living center of every "Thou" is seen to be eternal "Thou".
.
The eternal "Thou" is never known objectively,
but certitude comes through the domain of action.

Martin Buber (Hebrew: מרטין בובר‎; February 8, 1878, Franz-Josefs-Kai 45, Innere Stadt[1] – June 13, 1965) was an Austrian-born Jewish philosopher best known for his philosophy of dialogue, a religious existentialism centered on the distinction between the I-Thou relationship and the I-It relationship.[2]
Born in Vienna, Buber came from a family of observant Jews, but broke with Jewish custom to pursue secular studies in philosophy. In 1902, Buber became the editor of the weekly Die Welt, the central organ of the Zionist movement, although he later withdrew from organizational work in Zionism. In 1923 Buber wrote his famous essay on existence, Ich und Du (later translated into English as I and Thou), and in 1925 he began translating the Hebrew Bible into the German language.
In 1930 Buber became an honorary professor at the University of Frankfurt am Main, and resigned in protest from his professorship immediately after Adolf Hitler came to power in 1933. He then founded the Central Office for Jewish Adult Education, which became an increasingly important body as the German government forbade Jews to attend public education. In 1938, Buber left Germany and settled in Jerusalem, in the British Mandate of Palestine, receiving a professorship at Hebrew University and lecturing in anthropology and introductory sociology.
Buber's wife Paula died in 1958, and he died at his home in the Talbiyeh neighborhood of Jerusalem on June 13, 1965.
