Probabilistic predictive models of the mind, such as those naturally arising from evolutionary theory retain uncertainty, or more simply doubt as a fundamental generative principle. This gives rise to a intrinsic tone or ethic in both the cognitive and moral sense. If not merely the world by the metaphysic of the world are projections of mind then this doubt is also a projection and there ought also to be a phase of the same mind in which the negative place of doubt is filed, is a positive. This would then represent a form of knowing that was utterly ineffable in relation to ordinary, that is evolutionary knowing. That evolutionary knowing is one possible resolution of mind implies that this other kind of knowing also exists as an alternative resolution - like an equation with two solutions - one 'real' and one 'imaginary'. No extension of the real solution will ever yield the imaginary one, although the reverse is possible - just as real analysis is a special case of complex analysis but not vice versa.
