The transcendentals: unity, truth, goodness and beauty

Unity, truth and goodness are not separate regions of reality; they express being under relations to division, intellect and appetite.

Thesis exacta

What this dossier establishes

Every being is one, intelligible and desirable insofar as it is actual, while beauty manifests the harmonious radiance of form and goodness to apprehension.

Unity, truth and goodness are not separate regions of reality; they express being under relations to division, intellect and appetite.

The first distinction to hold in view is numerical and transcendental unity: Numerical one counts an item; transcendental unity signifies the undivided actuality of any being. This is not a preliminary definition to be memorized in isolation. It is the point at which an otherwise plausible objection either becomes exact or is shown to trade upon two different meanings.

Expositio fundamentalis

The argument in its philosophical setting

The exposition begins with Unity, truth and goodness accompany being and reveal its intelligible depth. It then shows how this part of first philosophy bears directly upon the exact thesis of the transcendentals: unity, truth, goodness and beauty.

Unum · verum · bonum

Unity, truth and goodness accompany being and reveal its intelligible depth

The transcendentals are not additional properties attached to some beings. They name being under aspects that extend beyond every genus. Every being is one insofar as it is undivided in itself; true insofar as it is intelligible and proportioned to intellect; good insofar as it is perfective and desirable. These notions are really grounded in being while differing conceptually according to relation and emphasis.

Unity explains why a substance is more than a heap. Truth explains why reality can measure judgment. Goodness explains why every appetite tends toward an apprehended perfection. Evil is consequently not a positive nature equal and opposite to good. It is a privation of due good in a subject: blindness in an eye, injustice in a will, disorder in an action. This account will later be indispensable for the problem of evil.

Beauty is often associated with the transcendentals because it joins intelligibility and delight: integrity, proportion and clarity make form present to a knowing subject in a way that pleases upon apprehension. One should not reduce beauty to private taste, yet concrete aesthetic judgment can involve cultural formation, bodily conditions and individual sensitivity. Its metaphysical root lies in the splendour of form and the fittingness of order.

The fourth way ascends through participated transcendental perfection; the fifth through ordered operation. Together they show that natural theology is not limited to asking why matter began. It asks why being is unified, intelligible, good and directed. The first cause must account for these features without receiving them in a limited mode from another.

Analysis profunda

Deeper analysis and consequences

The transcendentals “convert” with being: they have the same extension while adding a conceptual relation. Being is one insofar as it is undivided in itself; true insofar as it is intelligible and can measure intellect; good insofar as it is perfective and desirable. They are not interchangeable definitions, because each reveals a distinct ratio within the same actuality.

Unity does not deny composition. A living organism has many parts yet one substantial act and operation. Greater unity often accompanies greater actuality: a heap is less one than an organism; an organism’s functions are integrated into a life. The first cause, lacking all composition, is supremely one.

Truth has an ontological and logical aspect. Things are true as intelligible and conformed to their exemplar; judgments are true by conformity to things. Goodness follows actuality because perfection fulfils a capacity and moves appetite. Evil therefore cannot be a positive transcendental rival; it is privation in a good subject.

Beauty is often associated with integrity, due proportion and clarity. It adds a relation to cognitive delight. Because beauty can awaken desire for the transcendent, it has apologetic force, but aesthetic experience must not be confused with metaphysical demonstration. Beauty points through form and splendour to the source of truth and goodness.

Distinctiones

The distinctions on which the argument depends

Numerical and transcendental unity

Numerical one counts an item; transcendental unity signifies the undivided actuality of any being.

Ontological and logical truth

Ontological truth concerns the intelligibility of things; logical truth concerns conformity in judgment.

Ontological and moral goodness

A being is good insofar as actual; moral goodness concerns free acts ordered to the rational end. A morally evil act retains ontological goods while lacking due order.

Beauty and pleasantness

Pleasure can arise from appetite or habit. Beauty concerns form apprehended with integrity and proportion, though subjective conditions affect reception.

Obiectiones et responsiones

The strongest objections answered

Evil beings disprove the convertibility of being and good

Objection. A cruel act exists but is not good.

Reply. Its actuality, powers and chosen object are goods in the ontological order; the evil lies in privation of due moral order. Evil depends upon good as corruption depends upon a subject.

False things exist

Objection. A counterfeit coin is a being but false.

Reply. It is ontologically true as the kind of object it is; it is called false relative to an intended signification or judgment. The relations must be distinguished.

Beauty is merely cultural

Objection. Tastes differ radically.

Reply. Cultural formation affects apprehension, but integrity, intelligible form and proportion are objective features. Disagreement does not prove absence of an object any more than moral disagreement proves no goods exist.

Unity is reducible to convention

Objection. We choose what counts as one.

Reply. Conventional units exist, but the convention relies on real boundaries, continuities and operations. Organismic unity is discovered rather than assigned like the borders of an arbitrary collection.
