In 1831 Patrick Matthew included the social harm caused by exclusive interbreeding and opportunity blocking by those in the higher echelons of society who operate to keep others down and out.The Sutton Trust explains that social mobility in UK is stultified by those at the top keeping others down with unjust mechanisms fueled by bias. Patrick Matthew explained this in 1831. Was one reason his bombshell book was deemed heretical & seditious— Dr Mike Sutton (@Criminotweet) December 3, 2017
For that reason, as well as the heresy of his book in its mocking of the notion of a "God" as the origin of species and their extinction, Matthew's book was criticised. In particular, as text quoted below from a lengthy and prominent book review, people were implored to not even consider such heretical and seditious notions.
To this day, table scrap chasing creepily ambitious brown nosing toadies of the upper echelons of the scientific establishment still wish you not to read or ruinate on such notions as Darwin's plagiarism of Matthew, which was facilitated by such brute condemnation and censorship.
The United Service Journal and Naval and Military Magazine published an extended review in the 1831 Part II and 1831 Part III numbers of the magazine.
