Abstract
The topic of the in-between refers to the problem of the border, as long as it helps to clarify the understanding of the 'middle' as well as of part and whole and centric and eccentric. All these terms are closely related.
The in-between could almost be defined as the handling of the border that life itself is. This thesis is tried to prove itself in reference to Zhuāngzǐ, Platon, Nietzsche, Heidegger, Fink and Nishida.
