While Aristotle's writings on biology are considered to be among his best, the comments he makes about females in these works are widely regarded as the nadir of his philosophical oeuvre. Among many claims, Aristotle is said to have declared that females contribute nothing substantial to generation; that they have fewer teeth than males; that they are less spirited than males; and that woman are analogous to eunuchs. This book aims not to defend Aristotle's ideas about females but to defend Aristotle against the common charge that his writings on female species were motivated by ideological bias. The author points out that the tools of modern science and scientific experimentation were not available to the Greeks during Aristotle's time and that, consequently, Aristotle had relied not only on empirical observations when writing about living organisms but also on a fair amount of speculation. Further, he argues that Aristotle's remarks about females in his biological writings did not tend to promote the inferior status of ancient Greek women.
