Four primary colors

The primary colors that the brain (not the retina) perceives are


combining these gives the secondary colors


One can see that these secondary colors are intermediate between the primary colors

One would assume then that combining a primary color and a secondary color would result in a color intermediate between the primary and the secondary. And indeed most do. Except for cyan. Cyan is produced by combining blue light and green light but the color we perceive is not intermediate between blue and green.

The color we perceive as cyan is clearly a combination of blue and something. But what that something is is just not clear.

I suggest that there were originally four primary colors and that cy…

Sensing types develop strong beliefs based on information that is in the present, tangible, and concrete: that is, empirical information that can be understood by the five senses. They tend to distrust hunches, which seem to come "out of nowhere".

Intuition types tend to be more int…

Fear is like dirt and it washes right off.

Consciousness is being aware of being aware. Being aware means knowing what is happening. Computers know how to do things but don't yet know what they are doing.

Qualia are deeply mystifying. It is very hard to imagine how electrical signals passing through the microtubules of the brain could possibly produce something like the perception of colors.

But imagine a computer that knows what it is doing that is hooked up to a camera. Imagine that the computer is able to identify objects and intelligent enough to answer questions about what it is seeing. Obviously it must be perceiving some sort of sensation.

But that sensation would be like our perception of black and white. It would just be information. It …
