Aletheia, M. D. is a pseudonym for the anonymous author of the Rationalist's Manual published London : Watts & Co., 1897.
It was reviewed in The Literary World[1] which considered that "this work may be described as the reduction of human life to its lowest possible terms.
Anything that suggests other than animal and material considerations as a basis of conduct is to "Aletheia, MD," anathema-maranatha.
Religion is to be judged not by its ideals, but by its origins."
In 1967 it was again mentioned in Ethics[2] but as "sadly marred by Biblical criticism of a rather old-fashioned type."
