We distinguish four human colors, red, green, blue, and white.
We distinguish seven human tones.
We distinguish seven human voices.
We distinguish seven human smells.
We distinguish seven human tastes.
We distinguish seven human positions.
We distinguish seven human motions.
We distinguish seven human speeds.

We do not see ourselves as human beings but rather as animals of our world.
