“Only as a warrior can one withstand the path of knowledge. A warrior cannot complain or regret anything. His life is an endless challenge, and challenges cannot possibly be good or bad. Challenges are simply challenges.”

Free speech in an age of identity politics (2015)
Context: To accept that certain things cannot be said is to accept that certain forms of power cannot be challenged.... This is why free speech is essential not simply to the practice of democracy, but to the aspirations of those groups who may have been failed by the formal democratic processes; to those whose voices may have been silenced by racism, for instance. The real value of free speech, in other words, is not to those who possess power, but to those who want to challenge them. And the real value of censorship is to those who do not wish their authority to be challenged. The right to ‘subject each others’ fundamental beliefs to criticism’ is the bedrock of an open, diverse society. Once we give up such a right in the name of ‘tolerance’ or ‘respect’, we constrain our ability to challenge those in power, and therefore to challenge injustice.

“Life throws challenges and every challenge comes with rainbows and lights to conquer it.”
