The Kantian theory of an a priori intuition of space, the common condition of tactual and visual experience, because implied in sense-experience as such, is not conceived by Berkeley.
A plurality of co-existent minima of coloured points constitutes Berkeley's visible extension; while a plurality of successively experienced minima of resistant points constitutes his tactual extension.
After this he begins to unfold the antithesis of visual and tactual phenomena, whose subsequent synthesis it is the aim of the New Theory to explain.
Tactual or locomotive experience, it is implied, is needed to infuse true reality into our conceptions of distance or outness.
Do not we Occidentals shrink from many purely natural impressions by reason of repulsion developed through a morbid tactual sensibility?
Does the mere tactual sensation, in the first instance, and of itself, inform us that there is something external to ourselves, that what we feel is not a part of our own organism?
It is to be noticed, in addition, that with the exception of the tactual sense, and possibly of sight, these senses give us no direct, immediate knowledge of external things.
The tactual sensation would indeed very soon come to our aid in this cognition, and serve as a guiding sense, even in the absence of the former.
Subjectively it is the quality of stimulation due to a succession of impressions (tactual and auditory are most favorable) which vary regularly in objective intensity.
Although our examples have been drawn mostly from the field of music, the preceding principles apply to all kinds of rhythm, tactual and visual as well as auditory.
The common element cannot possibly be supplied either by the data of visual sensation which the blind do not possess, or by the data of passive tactual sensation which the vident hardly ever employ.
Indeed, the idea divests itself of the great bulk of the tactual details by which it was apprehended, whilst the muscular sensations which accompanied the act of palpation never seek to be joined with the idea.
Mach indeed claims to distinguish physiological Space, geometrical Space, visual Space, tactual Space as all different and yet apparently harmoniously blended in our Experience.
Diderot attempts to solve the problem by maintaining that tactual sensations occupy an extended space which the blind in thought can add to or contract, and in this way equip himself with spatial conceptions.
