Our ability to reason makes us what we are

Our ability to reason makes us what we are : 

Defective Perceptions 

Finally, the mystery of perception must be sorted out from defective perception. Humans suffer from certain peculiar visual defects. For example, we can fill in information that we partially see (if an edge is blocked out) but some animals don’t do that. Optical illusions have proven that our visual system is often wrong in its detection accuracy for size, shape, colour, motion, and depth. (Think of desert mirages where shimmering hot air looks like water.) Yet, in a sense, confining our examples to eyesight is misleading, since the world is created by blending all the senses, and variations in touch, taste, hearing, and smell lead to bewildering riddles…
Where Do We Humans Stand?

So while feeling superior to chickens with their hundred taste buds and ignoring bees, who can smell something miles away, or sharks, who can detect faint, distant electrical impulses, humans must take advantage of one extrasensory gift — our ability to reason — in order to find out where we stand in the shadowy realm of illusion versus reality.
