Capitalism in its imperialist stage leads directly to the most comprehensive socialisation of production; it, so to speak, drags the capitalists, against their will and consciousness, into some sort of a new social order, a transitional one from complete free competition to complete socialisation. Production becomes social, but appropriation remains private. The social means of production remain the private property of a few. The general framework of formally recognised free competition remains, and the yoke of a few monopolists on the rest of the population becomes a hundred times heavier, more burdensome and intolerable.
Human knowledge is not (or does not follow) a straight line, but a curve, which endlessly approximates a series of circles, a spiral. Any fragment, segment, section of this curve can be transformed (transformed one-sidedly) into an independent, complete, straight line, which then (if one does not see the wood for the trees) leads into the quagmire, into clerical obscurantism (where it is anchored by the class interests of the ruling classes).
Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?
Love... no such thing.
Whatever it is that binds families and married couples together, that's not love. That's stupidity or selfishness or fear. Love doesn't exist.
Self interest exists, attachment based on personal gain exists, complacency exists. But not love. Love has to be reinvented, that’s certain.
