Are essence and existence really distinct, or are they merely two ways of conceiving the same reality?

In this video, I examine one of the most fundamental disputes in Scholastic metaphysics: the distinction between essence and esse in created beings.

Beginning from the metaphysics of St. Thomas Aquinas, I explain what philosophers mean by essentia and esse, why Thomists insist that esse should not simply be reduced to the modern notion of “existence,” and why Aquinas describes it as the act of all acts and the perfection of all perfections.

I then compare the principal scholastic positions on the question:

the real distinction defended by the Thomistic tradition;
the formal distinction associated, according to some, with John Duns Scotus and the Scotist school;
theories of a modal distinction and formal-modal distinctions;
positions reducing the distinction to one of reason or conception;
the criticisms developed by later Scholastics such as Francisco Suárez and other opponents of the Thomistic thesis.

Particular attention is given to Cardinal Cajetan, whose arguments for the real distinction between essence and esse are reconstructed and analysed in detail, together with the broader Thomistic interpretation developed by authors such as Capreolus, Báñez, John of St. Thomas, and, in the modern period, Cornelio Fabro.

Among the questions considered:

What exactly is essence?
What is esse?
Is esse merely the fact that something exists?
Why does Aquinas call esse the act of all acts?
How is essence related to potency and esse to act?
Why is received esse said to be limited by the essence which receives it?
Does the composition of essence and esse imply a real distinction?
Could the distinction instead be merely formal, modal, virtual, or conceptual?
How do Thomists respond to the principal objections of **Scotists and Suarezians?
Can essence be understood without knowing whether the thing actually exists?
What does the distinction tell us about participation, causality, creation, and the metaphysical structure of finite being?
Why does the doctrine become decisive for understanding the difference between creatures and God as Ipsum Esse Subsistens?

The video also considers the historical diversity of Scholastic opinion, including debates surrounding Scotus, Ockham, Gabriel Biel, Henry of Ghent, Hervaeus Natalis, Francisco de Vitoria, Domingo de Soto, Melchor Cano, Pedro da Fonseca, and Suárez.

A central distinction throughout the discussion is that between the ordo essentiae and the ordo essendi: the intelligible constitution and receptive capacity of a thing on the one hand, and the act by which the constituted essence is actually placed in being on the other.

The objective is not merely to state the Thomistic conclusion, but to prove the real distinction philosophically, examine its strongest Scholastic alternatives, and answer the principal arguments raised against it.

Topics include Essence and Existence, Essence and Esse, Act and Potency, Thomistic Metaphysics, Thomas Aquinas, Cajetan, Cornelio Fabro, Duns Scotus, Francisco Suárez, Scholasticism, Real Distinction, Formal Distinction, Modal Distinction, Participation, Ipsum Esse Subsistens, Being, Metaphysics, and Philosophy of Being.
