ΥΠΟΚΕΙΜΕΝΟΝ

LEXARITHMOS 800

Hypokeimenon, a foundational term in ancient Greek philosophy, describes that which "lies beneath" as a basis, substratum, or substance. From its literal meaning, it evolved into a central concept for understanding existence and knowledge, particularly in Aristotle. Its lexarithmos (800) suggests completeness and fundamental culmination.

Definition

According to the Liddell-Scott-Jones Lexicon, the ancient Greek noun "ὑποκείμενον" (to) derives from the verb "ὑπόκειμαι" and literally means "that which lies beneath" or "that which has been placed underneath." Its initial usage is often spatial, describing a foundation, a substratum, or a base upon which something else rests or occurs.

Its philosophical significance was primarily developed by Aristotle, who established it as a technical term for "substance" or the "subject" that underlies changes and attributes. For Aristotle, the *hypokeimenon* is the prime matter (*prōtē hylē*) that receives forms, or the substance (*ousia*) that cannot be predicated of anything else but is itself the subject of categories. It is that which remains constant beneath alterations.

In grammar, *hypokeimenon* is used to denote the "subject" of a sentence, i.e., that about which something is said. In modern philosophy, the term also acquired the meaning of the "subject" of consciousness or knowledge, i.e., the knowing ego, in contrast to the "object" (*antikeimenon*) of knowledge. This evolution highlights the complexity and central position of the term in the history of thought.

Etymology

hypokeimenon ← hypokeimai ← hypó- + keîmai (root kei-)
The word "ὑποκείμενον" is the present middle participle (neuter) of the verb "ὑπόκειμαι," which is a compound of the preposition "ὑπό-" (under, beneath) and the verb "κεῖμαι" (to lie, to be placed, to be situated). The root "kei-" is an ancient Indo-European root (*ḱei-), meaning "to lie down, to recline."

The root "kei-" is highly productive in the Greek language, yielding a multitude of words related to placement, the state of lying, and endurance. From this root come words such as "koitē" (bed), "kōmē" (village, settlement), as well as compound verbs describing various positions and states.

Main Meanings

  1. That which lies beneath, foundation — The literal and original meaning, describing something positioned underneath another, serving as a base or substratum.
  2. Substratum, material — In a physical context, the material that forms the base or medium for something, e.g., the substratum of soil or the material undergoing processing.
  3. Subject of discussion, topic — The theme or subject of a discussion, inquiry, or thought, i.e., that "about which the discourse lies." (Plato, Theaetetus 184d).
  4. Grammatical subject — The term denoting the subject of a sentence, i.e., the person or thing performing the action or being spoken about.
  5. Philosophical substratum, substance — In Aristotelian philosophy, that which underlies changes and attributes, the prime matter or substance that cannot be predicated of anything else but is itself the basis of categories. (Aristotle, Categories 2a11-13).
  6. Prime matter — Specifically in Aristotle, the pure potential, the unformed substratum that receives form and becomes a concrete being. (Aristotle, Physics I 7, 191a8-12).
  7. Subject of consciousness — In modern philosophy, the knowing ego, the bearer of knowledge and experience, in contrast to the object of knowledge.

Word Family

kei- (root of the verb keîmai, meaning "to lie, to be placed")

The root "kei-" is an ancient and highly productive root in the Greek language, denoting the state of "lying," i.e., something being in a particular position, placed, or remaining. From this simple spatial concept, complex meanings developed concerning the foundation, substratum, endurance, and ultimately, in philosophy, the essence that "lies beneath" phenomena. Each member of this family explores a different aspect of the fundamental concept of placement and existence.

Philosophical Journey

The trajectory of "ὑποκείμενον" is a fascinating history of philosophical thought, from its literal use to its establishment as a central term for substance and consciousness.

5th-4th C. BCE
Pre-Socratics & Plato
The concept of an underlying substratum or *archē* (principle) exists in the Pre-Socratics. Plato uses the term rarely and primarily in its literal sense of substratum or topic of discussion.
4th C. BCE
Aristotle
Aristotle establishes *hypokeimenon* as a technical philosophical term. He defines it as the substance (*ousia*) that underlies changes and attributes, and as the prime matter (*prōtē hylē*) that receives form. It is the basis of existence and categorization.
3rd C. BCE - 2nd C. CE
Hellenistic Philosophy
The Stoics adopt the concept of *hypokeimenon* to describe the material substratum (*hylē*) that receives qualities and attributes, maintaining a materialistic interpretation of the Aristotelian concept.
3rd-6th C. CE
Neoplatonism & Patristic Theology
In Neoplatonism, *hypokeimenon* continues to be used in an Aristotelian sense. In Patristic Theology, the term *hypostasis* (also meaning "that which lies beneath," "subsistence") is used to denote the "person" of the Holy Trinity, differentiating it from *ousia* (nature).
17th-18th C. CE
Modern Philosophy
With the development of subjectivity, *hypokeimenon* (translated as 'subject') acquires the meaning of the knowing ego, the bearer of consciousness and knowledge, in contrast to the object of knowledge. Kant is a prime example of this usage.

In Ancient Texts

Aristotle is the philosopher who elevated *hypokeimenon* to a central term in metaphysics and logic. The following passages are indicative of its use:

«Οὐσία δέ ἐστιν ἡ μάλιστα καὶ πρώτως καὶ πρὸς ἣν τὰ ἄλλα πάντα λέγεται, ἥτις μήτε καθ’ ὑποκειμένου τινὸς λέγεται μήτε ἐν ὑποκειμένῳ τινί ἐστιν.»
Substance is that which is most and primarily and to which all other things are referred, which is neither predicated of any subject nor is in any subject.
Aristotle, Categories 2a11-13
«Ἔστι γὰρ τὸ ὑποκείμενον ἕν, οἷον ὁ ἄνθρωπος ἢ ὁ ἵππος, τὸ δὲ κατηγορούμενον πλῆθος, οἷον τὸ λευκὸν ἢ τὸ τρέχον.»
For the subject is one, such as man or horse, but the predicate is many, such as white or running.
Aristotle, On Interpretation 17a10-12
«Τὸ μὲν γὰρ ὑποκείμενον οὐσία, τὸ δὲ κατηγορούμενον συμβεβηκός.»
For the subject is substance, but the predicate is an accident.
Aristotle, Physics I 7, 190b23-24

Isopsephic Words (800)

Words from the Liddell-Scott-Jones lexicon sharing the same lexarithmos (800) as "ὑποκείμενον" include the following:

πίστις
«Pistis» (faith, trust) is conceptually linked to *hypokeimenon* as the basis or foundation upon which conviction and certainty rest. Faith is that which "lies beneath" as an internal conviction.
ὕπνος
«Hypnos» (sleep) describes a state of passivity and rest, where the body "lies" inert. The connection to *hypokeimenon* can be made through the idea of a passive substratum that receives the influence of sleep.
κύριος
«Kyrios» (lord, master) is one who "lies" in authority, the sovereign. The word denotes a dominant position or ownership, i.e., that which constitutes the basis of power or property.
Ω
«Omega» (Ω), the last letter of the Greek alphabet, symbolizes the end, completeness, and culmination. Its isopsephy with *hypokeimenon* may suggest the ultimate or foundational nature of the latter as the basis of all things.
Αἰθίοψ
«Aithiops» (Ethiopian) is a geographical and ethnological term. Its isopsephy with *hypokeimenon* is likely coincidental, without a direct conceptual link beyond the shared numerical value.
χοῖνιξ
«Choinix» (choenix) was an ancient unit of dry measure. As a measure, it serves as a "subject" of reference for quantity, a fixed basis for measurement.
