Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.
There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known. - Carl Sagan
I don’t believe this is true. The first version of the DSM had a section on sociopathic personality “disturbances,” with notes that these were sometimes referred to as psychopathy or sociopathy, but neither it nor the ICD “has ever included a disorder officially titled as such” (per the Wikipedia article on Psychopathy in the Diagnosis section).
Psychopathy was a catch-all for several different things, including homosexuality, so it makes sense for its use to have been retired in a clinical setting.
Antisocial personality disorder is the modern clinical term for sociopathy. ASPD is a Cluster B personality disorder and it has similarities to other Cluster B personality disorders: borderline personality disorder, histrionic personality disorder, and narcissistic personality disorder.
