This book is a critique of the three most prominent Australian “authorities” on Law and Ethics of the present day, namely John Finnis, Tracey Rowland, and Peter Singer. So far as the study of Natural Law is concerned the central figure is John Finnis. Peter Singer relates to it indirectly as adopting a position in Moral Philosophy that rejects Natural Law in any traditional sense and takes a naturalist position in a utilitarian sense. Tracey Rowland adopts a position that downplays Natural Law as knowable by human reason or philosophy outside the theological order of grace. The works of these philosophers provide the occasion for bringing back into focus some of the great truths of ethical and legal philosophy and for showing up, as best as one can from within, the diabolically perilous situation for our modern culture that has developed since the general breakdown of Christian civilization now so long ago as to be practically forgotten.
