Previously in the article entitled "Existence Does not Accept Propositions" we proved with some arguments that existence (meaning the absolute reality) does not accept propositions, and it is not possible for it to have propositions. Thus, we may not consider existence (meaning the absolute reality with all its different perceptions) as the subject of prime philosophy. Now in the present article, which follows the previous one, we attempt to clarify the obstacles that prevent the existence from accepting propositions and becoming the subject of philosophy. Altogether, we have mentioned four obstacles in this article including a) non-plurality of existence; b) refusal of accidents in reality of existence; c) refusal of accident of 'necessary by itself' and 'impossible by itself'; and d) and no demarcation for reality of existence. The present study aims at presenting the obstacles for existence to accept propositions in order to clarify that the subject of prime philosophy is not existence (meaning absolute reality with its different perceptions).
