因共同性不同，共同体有不同的层次，最高层次的共同体是生命的共同体。生命共同体的共同基础是生命同源，有共同的本体。人类命运共同体的至善即认知生命的本体及其秩序。这一秩序可以解析成先天秩序和后天秩序。社会政治哲学或者伦理学意义上的人类命运共同体和形而上学意义上的人类命运共同体显然有不同的视角。离开了对人类命运共同体的形而上学思考，社会政治哲学的思考是没有高度的。可以用先后天模式来处理两种思路的矛盾。人类命运共同体的运作可以解析成原生秩序原理和后天秩序原理。人类命运共同体意识需要有一定的形而上学的基础，如无一定的形而上学的基础，这一意识是不稳固的。
Communities are of different levels，due to the different shared cores on which the communities are formed.The highest level is the community of life，which means that all the lives have the same origination and noumenon.Therefore，the supreme good for the community with a shared future mankind means to know the ontological origination of life and its order，which can be divided into priori order and posterior order.However，it is quite manifest that the interpretation of the community of life in political philosophy and ethics takes perspectives different from that in metaphysics.It should be noted that the political philosophical understanding of the community of life can not reach a high magnitude without a solid metaphysical foundation.The two perspectives may be balanced by a posterior model，and the mechanism of the community of life may be interpreted from the models of priori order and posterior order.
