it's our brain that transforms these signals into colors. There are no colors in the "external world"; neither
is an apple red, nor the sky blue, nor the leaves green. They appear as they do simply because we percei-
ve them to be so.

Even a slight defect in the eye's retina can cause color blindness. Some sufferers perceive blue and
green as the same, some red as blue. At this point, it does not matter whether or not the outside object is
colored.
The prominent thinker George Berkeley also addresses this fact:

At the beginning, it was believed that colors, odors, etc., "really exist," but subsequently such views were

renounced, and it was seen that they only exist in dependence on our sensations. 344
In conclusion, the reason we see objects in colors is not because they are actually colored or have a

material existence in the outer world. The truth, rather, is that the qualities we ascribe to objects are all insi-
de us.
And this, perhaps, is a truth you have never considered before.

Mankind's Limited Knowledge

One implication of the facts described so far is that actually, man's knowledge of the external world is
exceedingly limited.
That knowledge is limited to our five senses, and there is no proof that the world we perceive by means

of those senses is identical to the "real" world.
