Medical Books and Articles

An important book on Abortion, since life begins at conception and not later, as Aristotle said. In the seventeenth century, two scientists Thomas Fienus and Paolo Zacchia who rejected the Aristotelian theory of delayed animation, made important historical contributions that led ultimately to the Church's abandoning the speculation that there is such a thing as unanimated (or non-human) fetus. Fienus, a professor of medicine at Louvain, published a biomedical treatise in 1620 on the formation of the fetus (De formatrice fetus liber). He concluded that the soul is infused on the third day. The Aristotelian notion of a succession of souls or "functions" of one soul (first vegetative, then sentient, and finally rational) made no sense to him. He developed nine lines of argumentation to support his thesis. In general, Fienus argues that the soul must be present at the beginning in order to organize the body. Moreover, in order to avoid an unnecessary multiplicity of explanatory factors, there must be one soul from the beginning that establishes the specific unity and individual continuity of the developing embryo.
