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. 
In societies that protect freedom of thought, thinkers always lack laws of thinking.
 the argument about freedom of thought is not valid.
