(i) “… human needs determine consciousness”
(ii) “The essence of man is the Origin, Cause and Goal of history …”
In THE ESSENCE OF CHRISTIANITY, Feuerbach examines the need for God, which he describes as an emotional need. This is true, but within that emotional need is also a need for an ultimate meaning to existence; a need for eschatological meaning; an answer to the question: where are we going?
The problem with this need is that it is easily manipulated: the very essence of religions is an indication of how sentimental attachments to symbols and fetishes can be easily implanted in society. Religions have also shown us how this implantation can be used by interested groups to socialise the masses in a way that is obviously beneficial to the groups that are controlling the manipulation. Religions are always, primarily, forms of exploiting the emotional need for existential and eschatological meaning in order to build easily controllable societies and cultures.
If we accept Feuerbach’s thesis that human needs determine consciousness and that God is an emotional need, we can see that obliterating what God is does not obliterate the problem of God, for, although we can obliterate religious superstition, without a substitute for God, we fail to satisfy the emotional need we have for an ultimate meaning to our existence.
To resolve this dilemma, we need to find another kind of final goal for humanity, one based on scientific and mathematical data, that can satisfy the human need for ultimate meaning and replace the purely mythical eschatologies of our religions. For example, it is a more positive idea if we construct our needs for ultimate meaning on the very physical and evolutionary nature of the cosmos, and our possible role within that evolution itself, rather than waiting for a supernatural End of Days.
We know that the Universe exists, and it is much easier to prove than the existence of God.
We can speculate on the purpose of the Universe in a scientific way, and such speculation can produce far more satisfying and pragmatic results than speculation on the existence of God.
Human purpose in the Universe depends on our relationship with the same Universe, and this idea ultimately leads to an interconnectivity between everything, both material and spiritual, that is lacking in the monotheistic religions that disparage the material in favour of an all-important, but also most-obscure idea of the spiritual.
In order to properly answer where we are going, we have to redraw our home, the where-we-are, away from the ambiguities of God, but not into the abyss of no-place, yet rather into the concrete reality of the Cosmos. Between God and No-God, lies the Universe.
If God is eternal, the Universe created itself out of nothing. If God is omnipotent, the Universe if driven by a blind will that needs sapient organisms (like us) to see. In God there can be no evolution; no authentic progress, whilst the Universe is always expanding and changing, and we are the conscious part of that evolution and change. In God, we are insignificant; in the Universe and its evolution to self-consciousness, we are a fundamental, purposeful ingredient.
