The discussion with sociology professor

I am taking "culture, self and identity" for this term. I expect this course to be one of most interesting courses in sociology.

The first lecture was on "culture". The professor defined "culture" into two types:
Culture (big C) and culture with a small c.

Then he went on explaining why the human beings as a unique biological specie though with diversified culture, yet share the common Culture (big c), in which each individual needs and relies on for survival and social development.

I asked him "What is difference then the big Culture from human nature?"

He said "in fact they are the same. however I am hesitated to use human nature as it has moral implication."

He then gave the detailed explanation by using evolution theory. The process of which the apes evolved into human beings has the significant effort in determining human beings as biological cultural creatures.

After lecturing, I asked him since evolution theory is not universally accepted, there are some other explanation such as in creation science. Will he accept other explanation to human beings Cultural nature?

We had the following dialogue:

me: "Since not everyone accepts evolution theory, will you allow those who do not offer other explanation such as from Creation science?"

the professor:"No, I would not allow. what is evidence?"

me,"for those who are Christian believes that God made the human beings, and the human beings ere made,in fact, God's image. That may well explain the unique biological cultural nature of human beings."

The professor:" I don't believe Bible, I don't believe God."

Me; "But evolution theory is not yet proven as law, There are many holes in it.It will take greater faith in believing evolution"

The professor:" We are talking about science, Evolution is a science with empirical evidences."

Me:"Theology is also science with empirical evidence."

....

We had lively discussion.

Finally, he said "By the way, it will be compulsory question in the final exam. I will disregard any other answers than what I had taught."

Me " I cannot give you answer against my own conviction, because I don't accept evolution theory."

The professor;" Then you have to change your conviction, it is your problem, not mine."

Me "Fine, I will leave it blank."

(did I sense a threat?)
