Anne Tilney’s Reviews > The Life and Prayers of Saint Thomas Aquinas > Status Update

Aquinas thought on the soul-nature of a human embryo was that as a zygote, the human's soul was of a nutritive or vegetative state like a plant's soul, therefore, at conception the embryo was not fully human, a direct contradiction of the RCC on abortion.

Later, he changed his thinking in his writing on abortion. Very fascinating.
