The Catechism of the Council of Trent was directed to all priests. The recently released Catechism of the Catholic Church was directed to all bishops. The Catechism of Pope St. Pius X is that pope's partial realization of a simple, plain, brief, popular Catechism for uniform use throughout the whole world. In other words it is directed to the layman . It was used in the ecclesiastical province of Rome and for some years in other parts of Italy. It was not, however, prescribed for use throughout the universal church.

An Introduction to Philosophy ought to live up to its name. It should tell the young collegian, and the presumably older non-collegian who takes it up with serious intent, a number of important things. It should answer the questions naturally to be expected of the person who wishes to be introduced,—questions such as these: What is philosophy? How did it come into existence? What interesting things have happened to develop it or to hinder its development?

A Class Manual in Major Logic by Paul J. Glenn explores how we know what we know, examining the criteria for truth and certainty. Rooted in Thomistic philosophy, it presents a rational defense of human knowledge against skepticism and relativism. The book discusses perception, judgment, reasoning, and the objective basis of truth, providing a clear, Catholic scholastic framework for understanding epistemology and logical analysis.

A Class Manual in Fundamental Metaphysics (1937/39) is a concise introductory text aimed at undergraduate philosophy students. It guides readers through the nature of being (“ontology”) as the core of metaphysics. Glenn explains fundamental concepts—being, existence, actuality, potentiality—then explores categories like substance, property, unity, truth, goodness, and classification of beings. The manual serves as a clear, structured groundwork in metaphysical principles

A Thomistic‑inspired manual (1941), Cosmology explores the nature of material reality. It begins with the “marks of bodily being,” then examines the constitution of bodies, their causes (material, formal, efficient, final), and laws of motion. Organized as a classroom text, it emphasizes metaphysical principles—substance, accidents, causality—within scholastic philosophy of nature.

This is a Thomistic philosophical textbook exploring life—from basic vegetal and sentient organisms to human beings. It outlines the nature and principles of life‑forces, the soul‑body union, sentient faculties and rational intellect, and free will, placing human psychology within a metaphysical framework. The manual eschews experimental methods for rational reflection on life, essence, species, and human nature.

This is a structured textbook in natural theology exploring rational proofs for God's existence and divine operations. It systematically presents a posteriori arguments based on causality and motion, examines God’s immanent and transient actions—creation, conservation, governance, and providence—and addresses the problem of evil, arguing that moral and physical evils serve a greater divine order and ultimate good.

This is a clear, accessible guide for students exploring the foundations of ethics. Covering topics like morality, virtue, relativism, and major ethical theories, it links ethics to philosophy more broadly. Designed for classroom use, it includes examples, exercises, and discussion questions.

This first volume of the smaller works of Thomas Aquinas includes the famous Compendium of Theology: the theological work Aquinas wrote at the request of his secretary, Reginald. It is basically a simplified version of the Summa Theologiae, since his secretary had requested a work on theology in less dense terms. This volume also contains the treatises On the Principles of Nature, On Being and Essence, On Separate Substances, and On Kingship.

This book presents a rigorous and updated defense of five major philosophical proofs for God's existence: Aristotelian, Neo-Platonic, Augustinian, Thomistic, and Rationalist. It explores the divine attributes required by these arguments—such as unity, simplicity, eternity, and omnipotence—and systematically responds to objections. It upholds the classical view that God's existence can be known with certainty by reason, countering both atheism and fideism.

In The Last Superstition, Edward Feser refutes the New Atheist claim that science has replaced religion. He argues the real conflict is not between science and religion but between two philosophies: the classical teleological view, which sees purpose in nature, and the modern mechanical view, which denies it. Feser shows that modern atheism rests on weak philosophical grounds, undermines reason and morality, and that classical thought better explains reality and supports the truth of religion.

Proves the truth of the Faith from a philosophic point of view. Covers proofs for the existence of God; His nature, attributes and action on the world; the nature of religion; the necessity and fact of supernatural revelation; Christ the Redeemer, True God and True Man; His Church--its marks and attributes; the necessity of the Church; plus, the Bible as the true word of God.

Scholastic Metaphysics offers a Thomistic overview of key metaphysical topics such as causation, substance, essence, and teleology. Centered on the Aristotelian theory of actuality and potentiality, it bridges traditional Scholastic thought with contemporary analytic metaphysics. While primarily Thomistic, it also considers Scotist and Suarezian views where they differ, helping both Scholastic and analytic readers engage across traditions.

Aristotle’s Revenge argues that core Aristotelian concepts—such as actuality and potentiality, form and matter, and final causality—are not only compatible with modern science but are essential to its foundations. The book explores topics like scientific realism, space and time, quantum mechanics, biology, evolution, and neuroscience, showing how Aristotelian metaphysics underlies and clarifies contemporary scientific and philosophical debates.

Real Essentialism defends the neo-Aristotelian view that objects have real, knowable essences that define what they are, despite changes. Challenging modern anti-essentialist thought from Wittgenstein, Quine, and others, the book argues for the reality of objective, immutable definitions and their relevance to science and metaphysics—exploring topics like biological species, the essence of life, and what it means to be a person.

The Metaphysics of Good and Evil is a modern analytic defense of the Scholastic view of good and evil, rooted in Aristotle, Augustine, and Aquinas. Good is seen as obedience to a thing's nature; evil, as a privation of that good. The book explores types of goodness across living and non-living beings and defends the privation theory of evil, arguing all evil is a deviation from natural goodness. It revives Scholastic insights for contemporary metaphysical and moral thought.

Analytic Philosophy: A Very Short Introduction by Michael Beaney explores the origins and development of analytic philosophy, from Frege and Russell to its global influence today.

It responds to modern errors and safeguards the integrity of the Catholic Faith.

Pastor Aeternus, issued by the First Vatican Council in 1870, defines the Catholic doctrine on the primacy and infallibility of the Roman Pontiff. It teaches that St. Peter was given primacy by Christ, which continues in the papacy. The pope has full, supreme authority over the whole Church. When speaking ex cathedra on faith or morals, he is infallible, protected by the Holy Spirit from error. This dogma is to be firmly believed by all Catholics.

""The study of the science of Apologetics is very necessary in these days of doubt and agnosticism. The fundamental principles which underlie all religious belief are daily called in question. And even if the urgent need of a reasoned grasp of the foundations of Faith did not exist, the interest of the subject of Apologetics, the large outlook upon life which it involves, the coherence of its parts and the cogency of its conclusions make it desirable that an examination into the principles of Theism should be an indispensable adjunct of Christian teaching."" - From the Preface

Saint Augustine's On Baptism Against the Donatists (c. 400 A.D.) is a seven-book refutation of the Donatist heresy, which wrongly denied the validity of sacraments administered by sinful clergy.

The book defends orthodox obedience in matters of doctrine.
