I think the problem is extremism, one must hold a balance between science,philosophy and religion, too much of anything is a bad thing.
I have a problem with the use of the word
extremism as a blanket term of abuse.
What is wrong with someone being extremely wise, extremely generous, extremely brave, extremely good looking, extremely kind and so on?
Yes but Byron is only warning against being extremely scientific, extremely philosophical or extremely religious, isn't he?
I mean some of us on here are extremely silly and Byron in no way warns against that, indeed he IS one of them, isn't he?
