We always look away and out as it were... our assertions are a "outlook', we are always looking away from ourselves out or towards something else up and away or beneath and below.... the question is: <what> has an outlook? what has a figure or story of "the way things are"? How is the perceiving instrument (however it is conceived or understood, or misconceived and misunderstood) and the "perceiver" (if it can be said to exist at all or is in any way demonstrable) integrated into and apart of the reality-view that is its outlook?
And is a theoretical vision, no matter how comprehensive and lucid, really sufficient in and of itself? Is there a way to go beyond "outlooks", no matter how comprehensive, systematic, explanatory, effective and illuminating they are? Or is the outlook our limitation. And if theory or thought is our limitation... and we are limited in time and space and scope and horizon of becoming and technical abilities... and if our condition is more or less unchangeable.... then theory is really subservient to a life-experience.... a day to day human experience with all its qualitative components and real-time richness and values..... and the ultimate reality is oblivion, rather then some eternal becoming or eternal Being in Rest in the platonic sense/dream. We must come to terms with what strikes us as reasonable! It seems to me that the life-experience of a finite human life.... is the the real space of our being.... and no other one that we dream about within that time-space which is our ultimate reality insofar as human life is concerned. Unless you believe in Plato's Being, the idea of another world that is without change and becoming and abides in rest. But to me that is wishful-thinking and can't be taken seriously. So here we have it. we are living it. this is reality! the finite human experience! And if your into documenting and enumerating laws and forces and clearly categorizing and analyzing phenomena.... then enjoy! But your not gonna find a transcendental ultimate world of Being as opposed to this world of becoming.
