Any species' sensorial image of their surroundings, if such there be, is necessarily entirely determined but neither apprehended nor comprehended, by the particular modalities of that species's sensoria.

For example, if an eye is shown by way of 'eyes' better than itself, to have three distinct receptors for dissimilar segments of a contiguous electromagnetic continuum then, even allowing for a certain overlap, then it can be concluded that it produces a raw datastream having sufficient properties to permit the phenomenon usually called 'trichromatic vision.'  This statement does not prescribe limits to sensoria and does not require additional information or prevent such from being gleaned in different ways.

Imagine a null-size point.  Call it A.  Now imagine a null-thickness line joining two arbitrary points; call this B.
