I do not want to go into its physical reasons: the construction of the human body is different from that of carnivorous animals. But man's intelligence is such that it can be utilised to defend any-thing he does whether right or wrong.
I didn't want to be the archetypal sponging brother-in-law so I didn't go into acting when I got to the States. I thought 'No I'll go to school and then I'll be an English teacher that'll be fun.' But I was horrible as a teacher. As hard as I tried I just couldn't inspire those kids to take an interest in Milton and Shakespeare and Donne.
