What is an example of metaphor in the novel, The Netanyahus?

Metaphor:

“Lawyers die and don’t become the law, doctors die and don’t turn into medicine, but biology and chemistry professors pass away and decompose into biology and chemistry, they mineralize into geology, they disperse into their science, just as surely as mathematicians become statistics.”

“I should just conclude with the antagonism between the belief that history never repeats itself and the belief that it always repeats itself, in the very circular eternity of this table.”
