Now come, this wisdom by my sweet toil sought Look thou perceive, lest haply thou shouldst guess That the white objects shining to thine eyes Are gendered of white atoms, or the black Of a black seed; or yet believe that aught That's steeped in any hue should take its dye From bits of matter tinct with hue the same. For matter's bodies own no hue the least-- Or like to objects or, again, unlike. But, if percase it seem to thee that mind Itself can dart no influence of its own Into these bodies, wide thou wand'rest off. For since the blind-born, who have ne'er surveyed The light of sun, yet recognise by touch Things that from birth had ne'er a hue for them, 'Tis thine to know that bodies can be brought No less unto the ken of our minds too, Though yet those bodies with no dye be smeared. Again, ourselves whatever in the dark We touch, the same we do not find to be Tinctured with any colour. Now that here I win the argument, I next will teach ***** Now, every colour changes, none except, And every... Which the primordials ought nowise to do. Since an immutable somewhat must remain, Lest all things utterly be brought to naught. For change of anything from out its bounds Means instant death of that which was before. Wherefore be mindful not to stain with colour The seeds of things, lest things return for thee All utterly to naught.
