Some people cannot read.
Some people do not know how to read.
Some people can read and know how to read, but nevertheless NEVER read a book (unless they're compelled to by work, school, etc.).
These three groups, equally, do not read.
Some people cannot participate in politics.
Some people do not know how to.
Some people can, and understand how, but don't.

Some people are blind from birth. Some people are mentally and/or physically retarded.
But those who live as if they are blind, as if they are retarded, due to a lack of will, they are truly blind, and truly retarded.

The will cannot be taught.
Those who lack the will lack something.

It's as real as a blind man's cane.
