Buber’s philosophy of dialogue views the human existence in two fundamentally different kinds of relations: I-It relations and I-Thou relations. An I-It relation is the normal everyday relation of a human being toward his or her surroundings. A person can also view another person as an It, and often does so by viewing others from a distance. In the I-Thou relation the individual enters into the relationship with another human with his or her entire being. This relationship becomes an intimate meeting, a real dialogue between both partners. Buber saw this as a reflection of the encounter between the human being and God. The I-Thou relationship allows for dialogue between the human being and God.
The following excerpt from I and Thou is reprinted with permission from the Balkin Agency, administrators of the estate of Martin Buber.
I contemplate a tree.
I can accept it as a picture: a rigid pillar in a flood of light, or splashes of green traversed by the gentleness of the blue silver ground.
I can feel it as movement: the flowing veins around the sturdy, striving core, the sucking of the roots, the breathing of the leaves, the infinite commerce with earth and air–and the growing itself in its darkness.
I can assign it to a species and observe it as an instance, with an eye to its construction and its way of life.
I can overcome its uniqueness and form so rigorously that I recognize it only as an expression of the law–those laws according to which a constant opposition of forces is continually adjusted, or those laws according to which the elements mix and separate.
I can dissolve it into a number, into a pure relation between numbers, and eternalize it.
Throughout all of this the tree remains my object and has its place and its time span, its kind and condition.
But it can also happen, if will and grace are joined, that as I contemplate the tree I am drawn into a relation, and the tree ceases to be an It. The power of exclusiveness has seized me.
This does not require me to forego any of the modes of contemplation. There is nothing that I must not see in order to see, and there is no knowledge that I must forget. Rather is everything, picture and movement, species and instance, law and number included and inseparably fused.
