«To me, Bruno is the supreme martyr for both free thought and critical inquiry… Bruno's critical writings, which pointed out the hypocrisy and bigotry within the Church, along with his tempestuous personality and undisciplined behavior, easily made him a victim of the religious and philosophical intolerance of the 16th century. Bruno was excommunicated by the Catholic, Lutheran and Calvinist Churches for his heretical beliefs. The Catholic hierarchy found him guilty of infidelity and many errors, as well as serious crimes of heresy… Bruno was burned to death at the stake for his pantheistic stance and cosmic perspective.»
