Interesting Fact
• Cardano was
eventually forbidden
to lecture or publish
books. He was
imprisoned in 1570
because he cast the
horoscope of Christ.
Influenced by Agricola
He felt that the “sense of hearing and the use of spoken words
were not indispensable to understanding ideas.”
Cardano was the first to make a connection
between deafness and mutism.
He found this subject interesting
because his oldest son was deaf in
one ear and Cardano, himself, had a
problem with stuttering.
Quote
“The writing is connected to speech
and the thought, but written letters
and ideas could be brought together
without the participation of read
sounds.”
Although Cardano wrote about
the deaf being able to learn even
thought they had no verbal
communication, he never went
further to study it.
