Приступљено 21. 3. 2014. „For Bruno was claiming for the philosopher a principle of free thought and inquiry which implied an entirely new concept of authority: that of the individual intellect in its serious and continuing pursuit of an autonomous inquiry… It is impossible to understand the issue involved and to evaluate justly the stand made by Bruno with his life without appreciating the question of free thought and liberty of expression. His insistence on placing this issue at the center of both his work and of his defense is why Bruno remains so much a figure of the modern world. If there is, as many have argued, an intrinsic link between science and liberty of inquiry, then Bruno was among those who guaranteed the future of the newly emerging sciences, as well as claiming in wider terms a general principle of free thought and expression.”
