Skepticism.

If anyone can show me one example in the history of the world

of a single Psychic 

who has been able to prove under reasonable experimental conditions that they are able to read minds


And if anyone can show me one example in the history of the world

of a single Astrologer

who has been able to prove under reasonable experimental conditions that they can predict events by interpreting celestial signs


And if anyone can show me one example in the history of the world

of a single Homeopathic Practitioner

who has been able to prove under reasonable experimental conditions that solutions made of infinitely tiny particles of good stuff dissolved repeatedly into relatively huge quantities of water has a consistently higher medicinal value than a similarly administered placebo...


And if anyone can show me one example in the history of the world
of a single Spiritual person

who has been able to prove either logically or empirically the existence of a higher power that has any consciousness or interest in the human race or ability to punish or reward humans for there moral choices or that there is any reason - other than fear - to believe in any version of an afterlife

I’ll give you my piano;

One of my legs;

And my wife.
