Garvey received regular letters from UNIA members and from his wife; she also visited him every three weeks. With his support, she assembled another book of his collected speeches, "Philosophy and Opinions"; these had often been edited to remove inflammatory comments about wielding violence against white people. He also wrote "The Meditations of Marcus Garvey", its name an allusion to "The Meditations of Marcus Aurelius". From prison, Garvey continued corresponding with far-right white separatist activists like Earnest Sevier Cox of the White American Society and John Powell of the Anglo-Saxon Clubs of America; the latter visited Garvey in prison.
