In this system the cessation of pain is of two kinds, impersonal and personal. Of these, the impersonal consists in the absolute extirpation of all pains; the personal in supremacy consisting of the visual and active powers. Of these two powers the visual, while only one power, is, according to its diversity of objects, indirectly describable as of five kinds, vision, audition, cogitation, discrimination, and omniscience. Of these five, vision is cognition of every kind of visual, tactual, and other sensible objects, though imperceptible, intercepted, or remote. Audition is cognition of principles, conversant about all articulate sounds. Cogitation is cognition of principles, conversant about all kinds of thoughts. Discrimination is cognition of principles conversant about the whole system of institutes, according to the text and according to its significance. Omniscience is cognition of principles ever arising and pervaded by truth, relative to all matters declared or not declared, summary or in detail, classified and specialised. Such is this intellectual power. The active power, though one only, is indirectly describable as of three kinds, the possession of the swiftness of thought, the power of assuming forms at will, and the faculty of expatiation. Of these, the possession of the swiftness of thought is ability to act with unsurpassable celerity. The power of assuming forms at will is the faculty of employing at pleasure, and irrespective of the efficacy of works, the organs similar and dissimilar of an infinity of organisms. The faculty of expatiation is the possession of transcendent supremacy even when such organs are not employed. Such is this active power. All that is effected or educed, depending on something ulterior, it is threefold, sentiency, the insentient, and the sentient. Of these, sentiency is the attribute of the sentients. It is of two degrees according to its nature as cognitive or incognitive. Cognitive sentiency is dichotomised as proceeding discriminately and as proceeding indiscriminately. The discriminate procedure, manifestable by the instruments of knowledge, is called the cogitative. For by the cogitant organ every sentient being is cognisant of objects in general, discriminated or not discriminated, when irradiated by the light which is identical with the external things. The incognitive sentiency, again, is either characterised or not characterised by the objects of the sentient soul.
