Zimmermann and Klassen compare Heidegger, Gadamer and Levinas:
Hans Georg Gadamer … emphasizes the point that ideas for our interpretation of the world do not simply pop into our heads from nowhere but are passed on to us through tradition.
…We must begin not with greater totalities such as Heidegger’s Being or Gadamer’s tradition but with our concrete social relation to other human beings. Philosophy does not come first in our reflections but the ethical relation to our fellow human being, and such a beginning is not Greek but Hebraic. It is in the Bible, argues Levinas, that we find the true ethical grounds for humanism: responsibility to one’s neighbor. It is this ethical demand of the other human being that limits one’s self-centered impulse for control over nature and others.
