Thoughts are almost always unfinished, unless you cap them and take possession over them with a value judgment, which evokes the ego and the eventual clashes against the ego. Capping something as good tends to stop thought around that thing for the time being, at least until the next evaluation, or else it deepens the progression of that thought, driven by instincts of love and reverence.
But capping something as good invites another to cap it as bad, and so back and forth it goes, with the progression of the thought being driven by love or hate, depending on the observer.
And this produces a social momentum - in the thinkers, speakers, and listeners alike - to anticipate a constant capping and a constant struggle over those caps, which continues on even over ideas in process, which are constantly torn asunder and never given a chance to fully develop in the public consciousness.
All of this has important social consequences, as value judgments over given thoughts can be socially cemented, and more quickly evoked in the mass consciousness, which is important for the direction of how thoughts develop, and what actions, behaviors, and material formations flow forth from them in the public sphere.
