Those who protect freedom of thought argue that freedom of thought is a prerequisite for intellectual progress. Because freedom of thought allows thinkers to follow their own ideas, no matter who they will offend and in what direction they will be led. However, one must dig out sufficient connections related to certain ideas in order to promote intellectual progress, and for this reason, thinkers need to think about laws. 
Without the law of thought, the thinker cannot have freedom of thought.
 the argument about freedom of thought is not valid.
