Shi'ite Hadith
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.

“Those who know, do. Those that understand, teach.”
This and many similar quotes with the same general meaning are misattributed to Aristotle as a result of Twitter attribution decay. The original source of the quote remains anonymous. The oldest reference resides in the works of George Bernard Shaw, Man and Superman (1903): "Maxims for Revolutionists", where he claims that “He who can, does. He who cannot, teaches.”. However, the related quote, "Those who can, do. Those who understand, teach" likely originates from Lee Shulman in his explanation of Aristotlean views on professional mastery: Source: Shulman, L. S.
