Reaction to the case of Tomáš Hudlický: Members of the Learned Society of the Czech Republic support the freedom of expression

„We believe that free exchange of ideas is a key condition for the pursuit of truth and that the honest opinions should be scrutinized, challenged or rebutted but not censored or suppressed,“ say 45 members of the Learned Society in a statement regarding the retracted opinion paper by Prof. Tomáš Hudlický.


The letter by Jan Konvalinka to the President and Vice-Chancellor of the Brock University regarding the retracted article of Prof. Tomáš Hudlický

Opinions could and should be challenged, questioned or refuted but never silenced. In order to be able to think, we have to have the right to inquire, question and even offend or be mistaken,” writes Assoc. Prof. Jan Konvalinka, a biochemist at the IOCB Prague and the Vice-Rector of the Charles University, to Gervan Fearon.
