The Inherent Goodness of Being: A Metaphysical Perspective

Why do philosophers say that everything that exists is, in some sense, “good”? This is not a feel-good platitude. It is a precise metaphysical claim with deep roots in Western philosophy. The idea that goodness is a transcendental property of being – something that belongs to every existing thing simply because it exists – has shaped centuries of philosophical and theological thought. Understanding this concept requires us to look at what “good” actually means in metaphysics, how it differs from everyday moral usage, and how it holds up against one of philosophy’s oldest challenges: the problem of evil.

What does “being” mean in metaphysics? 🔗

Before we can understand why being is considered good, we need to clarify what philosophers mean by “being.” In metaphysical discussions, being refers to the most fundamental fact about anything: that it exists. A rock, a tree, a thought, a person – all of these “are.” They have being. This concept is not limited to physical objects. Anything that has any kind of reality, whether concrete or abstract, participates in being.

For thinkers like Thomas Aquinas, being is not just one category among many. It transcends all particular categories – substance, quality, quantity, relation – and applies universally. This is precisely why the properties associated with being are called transcendental properties. They are not confined to any single genus or species of things. They apply to everything that exists.

The transcendental properties of being 🔗

In the medieval scholastic tradition, philosophers identified certain notions that are co-extensive with being itself. These are the transcendentals: concepts that unfold the meaning of being without adding anything essentially new to it. The most widely accepted transcendentals are unity (unum), truth (verum), and goodness (bonum). Some thinkers, including Aquinas, also listed res (thing), aliquid (something), and ens (being) itself.

The key idea is convertibility: each transcendental is interchangeable with being. To say that something “is” is also to say that it is one, that it is true, and that it is good. These are not separate facts layered on top of existence. They are different ways of looking at the same reality. As the Encyclopedia.com entry on transcendentals explains, these are not synonyms for being but characteristics that necessarily accompany it, adding conceptual content without adding a different reality.

Goodness as a transcendental property 🔗

Of all the transcendentals, goodness has perhaps provoked the most philosophical debate. In everyday language, “good” carries moral weight – we use it to praise actions, people, or outcomes. But in metaphysics, the meaning is broader and more fundamental.

What does it mean for being to be “good”? 🔗

Aquinas, drawing on Aristotle, defines the good as “that which all things desire” (Nicomachean Ethics, Book I). Everything that exists has some inclination, tendency, or drive – whether conscious or not – toward its own preservation, completion, or perfection. A plant turns toward light. An animal seeks food. A human being pursues knowledge and fulfilment. This tendency toward perfection, inherent in the very act of existing, is what philosophers mean by saying that being is good.

In Question 5 of the Summa Theologiae, Aquinas argues that goodness and being are identical in reality but differ in concept. Being refers to the fact that something is actual. Goodness refers to the fact that this actuality is desirable – that it represents some degree of perfection. A thing is desirable precisely because it is actual, and actuality is what makes things perfect. Therefore, everything that exists, insofar as it exists, is good.

The convertibility thesis 🔗

This is the famous convertibility thesis: ens et bonum convertuntur – being and good are convertible. They cover exactly the same range of things, but they highlight different aspects. Being highlights actuality. Goodness highlights desirability and perfection. Nothing that exists can lack goodness entirely, because to exist at all is to possess some degree of actuality, and therefore some degree of perfection.

This does not mean that everything is equally good. A fully grown, healthy oak tree possesses more of the perfection proper to oaks than an acorn or a diseased tree. According to the Internet Encyclopedia of Philosophy, Aquinas distinguishes between substantial being (the basic fact of existence) and relative being (the degree to which a thing has actualized its capacities). Substantial being gives a thing basic goodness. Relative being – how fully a thing has realized its nature – determines its degree of goodness.

Three kinds of goodness 🔗

When metaphysicians speak of the goodness of being, they are not referring to a single, undifferentiated concept. Goodness manifests in at least three distinct but related forms: ontological goodness, physical goodness, and moral goodness.

Ontological goodness 🔗

This is the most fundamental form. Ontological goodness belongs to every being simply by virtue of existing. A rock is ontologically good. A bacterium is ontologically good. Even something we might consider harmful or ugly possesses ontological goodness, because it exists and thereby has some actuality and perfection. This form of goodness is identical with being itself and is what the convertibility thesis directly addresses.

This is also why classical metaphysicians hold that no being is entirely evil. If something were completely devoid of goodness, it would have no actuality, no existence – it would simply be nothing. As Augustine wrote in his Confessions, if a thing were deprived of all goodness, it would cease to exist altogether.

Physical goodness 🔗

Physical goodness refers to the proper functioning and well-being of a thing according to its nature. A healthy animal, a well-formed crystal, a properly functioning organ – each of these exhibits physical goodness. This kind of goodness is tied to the fulfilment of a being’s natural capacities. A tree that grows tall, produces fruit, and sustains its ecosystem displays physical goodness. A tree ravaged by disease has lost some of this goodness – not its ontological goodness (it still exists), but the perfection proper to its nature.

Physical goodness, therefore, admits of degrees. Things can be more or less physically good depending on how fully they realize the potential inherent in their nature. This is closely linked to Aristotle’s concept of telos – the end or purpose toward which a thing naturally tends.

Moral goodness 🔗

Moral goodness applies specifically to rational beings – those capable of deliberate choice. For Aquinas, a human action is morally good when it is directed toward the genuine good of human nature as determined by reason. An act of kindness, a just decision, a courageous stand – these are morally good because they align with what reason identifies as truly conducive to human flourishing.

Moral goodness is not automatic. Unlike ontological goodness, which every being possesses simply by existing, moral goodness must be freely chosen. This is where the will comes in. Aquinas, as explained by Thomistic Philosophy, holds that an act directed by reason toward a true good is morally good, while an act that deviates from reason – pursuing an apparent good that is not genuinely perfective – is morally deficient.

This distinction matters greatly. It means that while every human being possesses ontological goodness, not every human action is morally good. The capacity for moral goodness is part of our nature, but its actualization depends on how we exercise our freedom.

The problem of evil 🔗

If being is inherently good, then where does evil come from? This is one of the oldest and most pressing questions in philosophy. If everything that exists is good, how do we account for suffering, cruelty, disease, and injustice?

Evil as privation of good 🔗

The classical metaphysical answer, developed by Augustine and refined by Aquinas, is that evil is not a thing in itself. Evil is a privation – an absence or lack of a good that should be present. Blindness is not a positive reality; it is the absence of sight in a being that, by nature, ought to see. Disease is not a substance; it is the disruption of healthy bodily functioning.

This is the privation theory of evil (privatio boni). It holds that evil has no independent ontological status. Evil cannot exist on its own. It always parasitically depends on something good – a being that exists and has some perfection, but is lacking a perfection it is supposed to have. As the privation account explains, evil is a departure from the goodness prescribed by a thing’s essential nature.

Natural evil and moral evil 🔗

The tradition distinguishes between two broad types of evil. Natural evil includes things like earthquakes, diseases, and predation – suffering that arises from the operation of natural processes. A lion killing a gazelle is not morally evil; it is the natural consequence of the lion fulfilling its own nature. But it does involve the privation of the gazelle’s life, which is a real loss of a genuine good.

Moral evil, on the other hand, arises from the free choices of rational agents. When a person lies, steals, or harms another, the evil consists in the failure to act according to reason – a deviation from the order that a rational nature ought to follow. Aquinas treats sin as a privation of the proper order in the will. The underlying powers of the will, considered in themselves, are good insofar as they are real. The evil lies in the misdirection, the falling short.

Can the goodness of being and evil coexist? 🔗

The privation theory does not deny that suffering and wrongdoing are real. What it denies is that evil is a positive substance or force in its own right. This allows defenders of the inherent goodness of being to maintain their position consistently. Evil is real in the sense that privations are real – blindness really does affect a person – but it is not real in the way that beings are real. It is an absence within being, not a rival to being.

This perspective also has implications for understanding free will. If human beings are to be capable of genuine moral goodness, they must also be capable of choosing wrongly. The possibility of moral evil is, in a sense, built into the structure of a world that contains free rational agents. Aquinas argues that some goods – compassion, courage, forgiveness – are logically impossible without the prior existence of suffering and wrongdoing. A world entirely free of evil would also be a world without certain profound moral achievements.

Why does this matter? 🔗

The doctrine that being is inherently good is not merely an abstract philosophical exercise. It has deep practical consequences for how we view existence, value, and ethics. If every existing thing carries intrinsic goodness, then existence itself has worth. This challenges nihilistic views that see the world as fundamentally indifferent or meaningless. It also provides a grounding for ethics that does not depend solely on subjective preferences or cultural norms. Goodness, on this view, is woven into the very structure of reality.

At the same time, the privation theory of evil offers a framework for confronting suffering without abandoning the conviction that reality is fundamentally ordered and valuable. It does not trivialize evil – genuine privation involves genuine loss. But it insists that evil is always secondary to good, always dependent on it, and never the last word about anything that exists.

The metaphysical tradition from Aristotle through Aquinas thus offers a vision of reality in which being, truth, goodness, and unity are not separate features that some lucky things happen to possess. They are built into the meaning of existence itself. Everything that is, in its own way, participates in goodness – however imperfectly, however partially.

What do you think? If every existing thing possesses some degree of inherent goodness, does that change how we should regard even those things we consider harmful or ugly? And can the idea of evil as a mere “absence of good” truly account for the depth of suffering we observe in the world?
