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.

You Can’t Separate Stewardship from Economics
As Christians continue toturn their attentionto the intersection of faith and work, it can be easy to dwell on such matters onlyinsofar as theyapplyto ourindividual lives. What is our purpose, ourvocation, and our value? How does God view our work, and how ought we to render it back tohim? What is the source ofour economic action? These questions are important, butthe answers will inevitably point us to a more public (and for some, controversial) context filled with profound questions of...
Mini-Grants on Free Market Economics
Are you a professor interested in free market principles? Do you know of one? The Acton Institute is offering mini-grants between $1,000-$10,000 for faculty at colleges, universities, and seminaries in the United States and Canada. The purpose of these mini-grants is to enhance the effectiveness in the teaching and scholarship of market economics. In the past, these mini-grants were only available for business and economics faculty at Christian schools, but this year any faculty (in the U.S. and Canada) working...
Samuel Gregg: The Anglosphere As Actor On The World Stage
Samuel Gregg, Acton’s Director of Research, asks whether or not the Anglosphere nations (Britain, Canada, New Zealand, Australia, and the United States) continue to be a viable political force in the world today at the Library of Law and Liberty. Gregg begins with his unique Anglosphere experience: Given that I am of Scottish and English descent, grew up in Australia, did my doctorate in Britain, and now live and work in America, I am about as much a product of...
Explainer: President Obama’s FY2016 Budget
What is the President’s budget? Technically, it’s only a budgetrequest—a proposal telling Congress how much money the President believes should be spent on the various Cabinet-level federal functions, like agriculture, defense, education, etc. (A PDF of the 150 page document can be found here.) Why does the President submit a budget to Congress? The Congressional Budget Act of 1974 requires that the President of the United States submit to Congress, on or before the first Monday in February of each...
Why Keep Funding Ineffective Government Programs?
Head Start doesn’t work. More people than ever are now on food stamps. Medicaid is staggering under the weight of its own bloat. Why are we continuing to fund bad programs? This is what Stephen M. Krason is asking. Such programs keep expanding: There has been a sharp increase in the food-stamp and Children’s Health Insurance programs. Obama has proposed more federal funding for Head Start and pre-school education generally, job training for laid-off workers, and Medicaid. In fact, the...
A Parable for the Entrepreneur
In this week’s Acton Commentary, “A Parable for the Unemployed,” I provide a brief survey of the biblical view of work, concluding with reference to the parable of the workers in the vineyard in Matthew 20. As I argue, this parable “might just as well be called the parable of the jobless. It teaches us to wait patiently and expectantly for ways that we can be of service to God through serving others.” Or as the Theology of Work mentary...
Why Government Money Alone Can’t Fix Poor Schools
The largest initiative bat poverty by funding public schools has occurred in Camden, New Jersey, the poorest small city in America. New Jersey spends about 60 percent more on education per pupil than the national average according to 2012 census figures, or about $19,000 in 2013. In Camden, per pupil spending was more than $25,000 in 2013, making it one of the highest spending districts in the nation. But as notes, all that extra money hasn’t changed the fact that...

Affordable Energy Drives Basic Needs in the Developing World
“Give a man a fish and you feed him for a day,” wrote Maimonides. “Teach a man to fish and you feed him for a lifetime.” With all due respect to Maimonides, much has happened since the 12th century. Among those changes is inexpensive, plentiful energy which powers refrigeration, which frees a man from the burden of fishing every day and allows him to engage in other worthy pursuits. That is only if the progressive crusade to strand fossil fuels...
