How do we know what’s real? For that matter, how do we know what we know? An introduction to philosophy in the Catholic tradition is a great place to look for answers.

If you are looking for an accessible introduction to philosophy in the Catholic tradition, James M. Jacobs’ new book, Seat of Wisdom, is a great place to begin. To be sure, any entrance into philosophy takes patience and hard thinking, and Jacobs’ book is no exception, but anyone willing to put forth the effort will surely gain a richer understanding of reality and the meaning of human existence—and human rights.

The Catholic philosophical tradition, also known as “perennial philosophy,” has its roots in the ancient Greek philosophers Plato and Aristotle. The term “perennial” indicates both that it deals with timeless wisdom and that its core insights have been sharpened by a long line of philosophers over the course of millennia. The tradition began when the Greeks used reason to discover the unity underlying the diversity in the world around them. To see what they were getting at, consider that the things we experience are both “one” and “many.” For example, the various branches and leaves of a tree constitute its many parts. Yet those parts are unified by the wholeness of the tree itself. Thus, there is both diversity (or “manyness”) and unity (or “oneness”) to things in the world. Moreover, this pattern is not confined to any particular thing, like a tree, but also extends to classes of individual things, like a group of trees. For instance, each tree in a forest is unique in size, shape, and its quantity of branches and leaves, and yet we nevertheless know that each one is in fact a “tree” and not, say, a dog, a cloud, or a blade of grass. In other words, trees in a forest are both many (in their diversity) and one (in that they all equally count as “trees”). This “one-and-many” dynamic, then, pervades reality, and making sense of it constitutes the core of a branch of philosophy known as metaphysics.

However, ever since the Enlightenment, philosophers have tended to deny one side or the other of this equation. That is, modern philosophy has rejected either the oneness or the manyness displayed in the world. This has resulted in a reductionist view not only of reality but also of the human person. As Jacobs puts it: “The problematic reductions in metaphysics arise from accepting one truth so as to minimize or exclude the other. Either the philosopher emphasizes the sameness of being (a position known as monism) and reduces all differences to a mere illusion, or he emphasizes the difference between beings (a position known as pluralism), which makes the universe unknowable because there is mon principle of intelligibility.”

Unlike these modern reductionist approaches, however, perennial philosophy accepts both truths and builds on the foundations laid by early philosophers, especially Plato and Aristotle, to account for them. Plato understood the “one and the many” through his theory of the Forms. To understand his view, consider the forest once more. What explains the unity of the trees? According to Plato, each tree shares or “participates in” the Form or essence of being a tree, or “treeness,” which is why we recognize that a forest posed of “trees” rather than dogs, clouds, or blades of grass. The Form of a tree gives individual trees both their unity and their intelligibility, and since it is immaterial, unchanging, and eternal, Plato believed that Forms have more reality or “being” than things in the world, which are material, changing, and temporal, and that therefore the Forms must exist in a realm separate from the material world we inhabit.

Plato’s student, Aristotle, accepted the reality of Forms but disagreed with Plato about where they exist. Aristotle argued that the forms must exist within the very structure of the world itself, rather than in another realm. Furthermore, he argued that individual things, or what he called “substances,” posed of both form and matter, the form being the essence or nature of a thing, while matter is what receives and individuates the form. Take the tree example above. In Aristotle’s view, a tree is a substance that posed of form (“treeness”) and matter (that which has the potential to receive the form). To put it in more Aristotelian jargon, the form of a tree “actualizes” the matter (of, say, an acorn), making a potential tree an actual tree (a substance). Form and matter are thus co-constituents of things and necessary principles for making sense of reality.

Subsequent philosophers down the ages built on these general metaphysical outlines, including Plotinus, Augustine, Boethius, and the Scholastic philosophers of the Middle Ages. But the most important contribution came from philosopher and theologian Thomas Aquinas, bined Aristotle’s form-matter structure with Plato’s “participation” framework. Aquinas’ key insight was his existence-based metaphysics. That is, more fundamental to reality than Plato’s Forms or Aristotle’s substances is the nature of existence itself. As Jacobs puts it:

Plato had used the idea of participation to explain how the Forms as essences relate causally to changing material things: brown things participate in the Form of brown; tall things participate in the form of Tall; just things participate in the Form of justice. One of the problematic assumptions in this argument is that Plato assumes that the Forms of brown, or tall, or justice necessarily exist. It is clear, though, that none of these finite realities has toexist. Indeed, the only thing that must exist is existence itself. Consequently, Thomas argues that things that do not have to exist (such as the Forms) only exist by virtue of participation in existence.

Furthermore, for Aristotle’s part, he argued that forms actualize the matter of individual substances (as we saw above). But Aquinas points out that the same principle can be applied to essences themselves—that is, the potential of any form is actualized by its participation in the act of existence, and the more a form participates in existence, the more real is the being who has that form. In other words, there are degrees of being depending on the degree to which the essence of a thing participates in the act of existence. In this way, bines Plato and Aristotle to draw a distinction between the essence and existence of things. Moreover, with this distinction in hand, Aquinas demonstrates why a being whose essence is existence, or God, must exist. Though his metaphysics can be quite abstract, the gist of it is as follows. If essence and existence are distinct in everything we experience, if all things in the world receive their existence from something other than what they are (their essence or form), then there must be a being whose essence simply is existence on which all things depend. For without such a being imparting existence to the things in the world around us, things would not exist. But, because we do indeed experience things, we know that they do in fact exist. Ergo, a being whose essence is existence must exist, and this we call “God.”

Jacobs proceeds to walk the reader through these deep metaphysical caverns because, as he explains, metaphysics is fundamental to everything else. In fact, whether one realizes it or not, one’s metaphysics ends up shaping one’s views of everything—from anthropology (or view of the human person) to ethics.

For example, the nature or essence of a human being is classically understood as a “rational animal.” However, if one denies that forms or essences are objectively real, then there is no such thing as human nature (as the terms “rational” and “animal” have no ultimate meaning); and if there is no such thing as human nature, then there is no such thing as human rights; and if there is no such thing as human rights, then who has what rights can be decided by any given society. This is precisely what has happened over time, which has led to some bizarre consequences. For instance, Jacobs explains that “in recent years, Belgium has extended human rights to chimpanzees and Bolivia has granted human rights to forests. Once we ignore how natures ground reality, we are liable to invent the most groundless fantasies.”

No less importantly, Jacobs covers other terrain that follows from metaphysics, like epistemology (or how we know reality), morality, the nature of evil, political philosophy, as well as philosophy of mind and free will. Although the beginner may find some sections more challenging than others, at the very least he or she will walk away from the book with a stronger appreciation of both the depth and reach of perennial philosophy in the Catholic tradition. For that, it is a highly mended read.

How To End Poverty By Jim Wallis
It is not often that Sojourners president Jim Wallis puts forth ideas that align with those of the Acton Institute. However, in a recent interview, Wallis (touting his new book, mon Good: How the Gospel Brings Hope to a World Divided)said that he recognizes that there are three keys to ending poverty: work and economic activity, innovation, education. He also says his hometown of Detroit has a big lesson to teach us: Detroit shows that the government isn’t enough,” said...
Unemployment is a Spiritual Problem
The longer that Americans are unemployed, the more likely they are to report signs of poor psychological well-being. A recent Gallup survey found that about one in five Americans who have been unemployed for a year or more say they currently have or are being treated for depression. Gallup finds that unemployed Americans are more than twice as likely to say they currently have or are being treated for depression than both those with full-time jobs and those who have...
If We Ban Sex-Selective Abortions, Are We Being Racist?
. The premise Ms. Bazelon puts forth is that the growing movement to make sex-selective abortions illegal in the U.S. is based on racial biases towards Asians, e from cultures where sex-selective abortions are mon. Bazelon states, The International Human Rights Clinic of the University of Chicago Law School and the National Asian Pacific American Women’s Forum are publishing a new study that exposes banning abortion based on sex-selection for what it is: a way to restrict abortion, not bat...
What Libertarians Can Learn from Edmund Burke
In his new book, The Great Debate, Yuval Levin explores the birth of America’s Left and Right by contrasting the views of Thomas Paine and Edmund Burke. I’ve written previously on his chapter on choice vs. obligation, and in a recent appearance on EconTalk, Levin joins economist Russell Roberts to discuss these tensions further, addressing the implications for libertarians and conservatives a bit more directly. It should first be noted that Roberts and Levin offer a dream pairing when es...
How Religious Freedom Helps the Poor
Freedom to practice one’s faith and be a person of faith can be instrumental in enabling the poor to achieve some modicum of social and economic freedom, says Rebecca Shah: Religion is no panacea, but aspects of religion can activate certain practices and partnerships among its adherents that can motivate and encourage economic development. If modern economics continues to yield an understanding of human development that ignores the role of religion, governments and development institutions will persist in acting as...
Schooling Journalists In Religion
Do you know the name of the author and publisher of the Book of Ephesians? Do all Mormons practice polygamy? What about the two major branches of Islam? Apparently, many journalists don’t know the answers to these questions either. (That first one was a real question asked by a journalist to Michael Cromartie, of the D.C.-based Ethics and Public Policy Center.) Given how much religion informs the lives of most people on the planet, and our news, it is a...
John Nash: A Beautiful Austrian Mind?
My older son’s college psychology class was recently assigned the film A Beautiful Mind, about the Nobel Prize winning economist and schizophrenia sufferer John Nash. The assignment was to watch the film, dig into Nash’s biography, and report on how the film altered Nash’s story of mental breakdown and recovery. We watched the film together as a family (my second viewing), checked out the biography by Sylvia Nasar from a local library, and generally geeked out on Nash and game...
U.S. Southern Borders Overwhelmed By Children
It has long been apparent that U.S. borders are far from secure. Border patrol agents are stretched thin, especially along the southern states, dealing with illegal immigrants, human traffickers and smugglers, and the drug cartels. Now, there is a new problem with no easy solution: children teeming into the U.S., many under the age of 12. According to The Washington Times, The flood of young children pouring across the southwestern border is worse than the administration has previously acknowledged, and...
Jonathan Witt on the Failure of ‘Social Business’
Jonathan Witt, research fellow at Acton, recently wrote a piece at The Federalist about “social business.” He argues that it might do more good to own and operate an ethical business that follows through on its contracts and “respects the dignity of employees and customers,” rather than trying to have a “social business.” Witt begins by talking about a cardboard bike. In 2012, Izhar Gafni became relatively famous by creating a sturdy cardboard bike that could be sold to the...
No Doubt About It: Human Trafficking Is Big, Big Business
It is a business that exists in the shadows. You won’t see a billboard for a domestic slave, nor a glossy magazine spread for the latest in forced labor. While cities struggle to rid their streets of prostitutes, they forget these people are victims of crime. Yet, make no doubt: human trafficking is big, big business. The International Labor Organization (ILO), a United Nation’s agency dealing with labor issues, has released a report makes clear the financial aspects of human...
