it is necessary that at least once in your life
you doubt, as far as possible, all things.’ Descartes
This I think inspired the Real Live preacher to make the following list-
Here is a list of things we speak of as if they were real, but they do not exist:
Squares and Circles
1 dimensional lines
2 dimensional objects
An inch
The poor*
The rich*
The sky
Perfection
Ten pounds
Infinity
4
Pacifism
God as any human has described God.
