According to Martin Buber, “… without It a human being cannot live. But whoever lives only with that is not human”

Question

What is the meaning of this quotation?

Answer 1

I think to understand the quote, more context is necessary. Without the passage the quote is from, it's not clear what the 'It' refers to or what 'that' refers to. But if you can provide the full passage, I could definitely help you understand the full quotation.
