"About the terminating of pregnancy, I want your opinion. The father was syphilitic. The mother tuberculous. Of the four children born, the first was blind, the second died, the third was deaf and dumb, the fourth was also tuberculous. What would you have done?"
"I would have terminated the pregnancy."
"Then you would have murdered Beethoven."
For the record, Beethoven was his parents' second child, his father was not syphilitic, and so far as we know, none of his siblings were born with severe birth defects, although four of the seven Beethoven offspring died in childhood.
