Context

“but no one conceals his good fortune, nay sometimes people even pretend to have such advantages as they do not really possess. So the curious man, eager to hear a history of what is bad, is possessed by the passion of malignity, which is brother to envy and jealousy. For envy is pain at another's blessings, and malignity is joy at another's misfortunes: and both proceed from the same savage and brutish vice, ill-nature. 244§ vii. But so unpleasant is it to everybody to have his private ills brought to light, that many have died rather than acquaint the doctors with their secret ailments.” source
