What I have learned, over the last 20 years, is that the solution to fear was right under my nose. And the one who found it was my cat.

Fear is the primordial emotion. When the first vertebrate animals
appeared on this earth 500 million years ago, fear was among the
most important neurological innovations that helped them survive.
Microorganisms had, for billions of years, developed ways to avoid
things that could cause them harm, e.g., a simple chemical avoidance
signal: “Move Away.” But as these tiny creatures evolved, their
bodies (and minds) became larger and more complex, requiring the
coordination of appendages, organs, and billions of cells. The
simple chemical avoidance signals could no longer do the trick. It
was not until the evolution of fear that larger, multicellular
organisms – like animals – could organize their entire biological
apparatus to avoid impending threats. Fear was like a flashing
danger sign that would warn every part of an animal’s body that it
was time for “fight or flight.”
The solutions to this problem have been the subject of countless
studies and dissertations. Entire fields of psychiatry and sociology
and political science have been devoted to the problem of fear. And
yet what I have learned, over the last 20 years, is that the
solution to fear was right under my nose.
And the one who found it was my cat.
