This paper is an attempt at establishing the relation between metaphys
ics and ethics. The starting paint of the analysis is the fundamental
question of metaphysics: ''Why is there something rather than nothing?
'' When this question is examined as to its object, the question does
not appear to be legitimate, for neither the being, without any furthe
r determination, nor the mere nothing can be objects of a question. Bu
t reflecting the act of questioning as real, we find in its pure openn
ess the being as a whole. Questions can be asked and answers given on
the being - it is therefore intelligible., as put into a question that
can never be definitively answered, the being is truly problematic. I
n this aporia, the being appears ambigous: it is everything and at the
same time nothing. It founds everthing and is itself without a founda
tion. In spite of this aporia, the act of questioning is not dissolved
; action in the form of asking and answering is unavoidable. With rega
rd to the fundamental aporia of the questionable and problematic being
, we seek a more comprehensive mediation. This is not possible in the
horizon of being as pre-given to our knowledge. Turning our attention
toward the horizon of being as imposed on our actions, we find the sam
e-aporia. However, the relation between the subject and the object in
the theoretical and the practical question is determined in a reverse
way. In this reversed symmetry lies the possibility of a sought mediat
ion. The being reveals itself in a suspend balance. The principle of i
dentity in thinking and the principle of relevancy in acting are mutua
lly conditioned. In this mediation of theory and practice subsits the
(perhaps sole) possibility of foundation of metaphysics and ethics in
the same time. In this way, we are attempting to go with Heidegger bey
ond Heidegger.
