The Challenge
The atheist professor of philosophy asked one of his new Christian students to stand.
"Is God good?"
"Sure! God's good."
"Is there sickness in this world? Immorality? Hatred? Ugliness? All the terrible things- do they exist in this world?"
The student squirms."Yes."
"Who created them?!"
[No answer.]
"God created all evil, didn't He, son?"
The lecturer breaks away to pace in front of the classroom like an aging panther.
"Tell me," he continues, "How is it that this God is good if He created all evil throughout all time?" "Do you believe in Jesus Christ, son?"
The student says in a small voice, "Yes, professor, I do."
The old man shakes his head sadly. "Science says you have five senses you use to identify and observe the world around you. Have you seen Him?"
"No, sir. I've never seen Him."
"Then tell us if you've ever heard your Jesus, felt your Jesus, tasted your Jesus or smelt your Jesus? Do you have any sensory perception of your God whatsoever?"
"I'm afraid I have not."
"So according to the rules of empirical, testable, demonstrable protocol, science says your God doesn't exist. What do you say to that, son? Where is your God now?" The young man looks defeated.
Another Christian raises his hand to speak. "Sir, is there such a thing as heat?"
"Yes," the professor replies. "There's heat."
"Is there such a thing as cold?"
"Yes, son, there's cold too."
"No, sir, there isn't."
The professor's grin freezes.
The second Christian continues. "You can have lots of heat, super-heat, mega-heat, white heat, a little heat or no heat, but we don't have anything called 'cold'. We can hit 458 degrees below zero, which is no heat, but we can't go any further after that. You see, sir, cold is only a word we use to describe the absence of heat. We cannot measure cold. Heat we can measure in thermal units because heat is energy. Cold is not the opposite of heat, sir, just the absence of it."
Silence. A pin drops somewhere in the classroom.
"Similarly, immorality is merely the absence of morality. Injustice is the absence of justice. Is there such a thing as evil?"
The Christian pauses.
"Isn't evil the absence of good? God did not create evil."
The professor's face has turned an alarming colour. "As a realist, I absolutely do not recognise the concept of God or any other theological factor as being part of the world equation because God is not observable."
"Sir, you rightly state that science is the study of observed phenomena. Is there anyone in the class who has ever seen the professor's brain?"
The class breaks out in laughter.
The Christian points towards his elderly, crumbling tutor. "Is there anyone here who has ever heard the professor's brain, felt the professor's brain, touched or smelt the professor's brain?
[pause]
No one appears to have done so."
The Christian shakes his head sadly. "It appears no one here has had any sensory perception of the professor's brain what-soever. According to the rules of empirical, stable, demonstrable protocol, science, I declare that the professor has no brain."
