Beyond a doubt truth bears the same relation to falsehood as light to darkness.

Painting is concerned with all the 10 attributes of sight; which are: Darkness, Light, Solidity and Colour, Form and Position, Distance and Propinquity, Motion and Rest.

The beginnings and ends of shadow lie between the light and darkness and may be infinitely diminished and infinitely increased. Shadow is the means by which bodies display their form. The forms of bodies could not be understood in detail but for shadow.

Truth at last cannot be hidden. Dissimulation is of no avail. Dissimulation is to no purpose before so great a judge. Falsehood puts on a mask. Nothing is hidden under the sun.

The truth of things is the chief nutriment of superior intellects.

To attempt seeing Truth without knowing Falsehood. It is the attempt to see the Light without knowing the Darkness. It cannot be.
