ΕΝΔΕΧΟΜΕΝΟΝ

LEXARITHMOS 949

The concept of ἐνδεχόμενον, central to Aristotelian philosophy, describes that which is possible to happen or not to happen, the contingent, in contrast to the necessary and the impossible. It is not merely a probability, but an inherent potentiality of being or non-being, a state that "admits within itself" the alternative. Its lexarithmos (949) reflects the complexity of the concept, linking acceptance (δέχομαι) with internal possibility (ἐν-).

Definition

In classical Greek philosophy, particularly in Aristotle, τὸ ἐνδεχόμενον (the neuter of the participial adjective ἐνδεχόμενος) refers to anything that is "possible to happen" or "possible not to happen," i.e., the contingent. It is not merely the probable, but that which possesses the inherent potentiality to exist or not to exist, without being necessary or impossible.

This concept is fundamental to Aristotelian logic and metaphysics, as it distinguishes three modes of existence or occurrence: the necessary (ἀναγκαῖον), the impossible (ἀδύνατον), and the contingent (ἐνδεχόμενον). The contingent is characterized by the absence of necessity and the presence of alternative possibilities. For instance, "it is contingent that it will rain tomorrow" means that it may or may not rain, with neither outcome being predetermined.

Beyond philosophy, the word is also used in the broader sense of "permissible," "acceptable," or "possible" in general circumstances. The verb ἐνδέχομαι means "to admit within itself," "to allow," or "to be possible." Its meaning is closely tied to the idea of acceptance or the capacity for something to "fit" within a framework or situation.

Etymology

ἐνδεχόμενον ← ἐνδέχομαι ← ἐν- + δέχομαι (root δέχ-, meaning "to receive, accept")
The word ἐνδεχόμενον derives from the verb ἐνδέχομαι, which is compounded from the preposition ἐν- ("in, within") and the verb δέχομαι ("to receive, accept"). This compound signifies the idea of "admitting within itself," "allowing," or "being capable of containing." The root δέχ- is an Ancient Greek root belonging to the oldest stratum of the language, expressing the act of reception, acceptance, and taking.

From the same root δέχ- stem many words related to acceptance, reception, and possibility. The simple verb δέχομαι forms the core of the family, while its derivatives such as δοχή (reception), δεκτός (acceptable), and compound verbs like ἀποδέχομαι (to accept, approve) and ὑποδέχομαι (to receive, welcome) expand the semantic field. Ἐνδέχομαι, in particular, adds the notion of internal possibility or permissibility.

Main Meanings

  1. That which may or may not happen — The primary philosophical meaning, especially in Aristotle: that which is neither necessary nor impossible, but possesses the inherent potentiality for both states. E.g., «τὸ ἐνδεχόμενον καὶ μὴ ὂν καὶ ὄν» (Aristotle, On Interpretation 9, 19a 9-10).
  2. The permissible, the acceptable — That which can be received, allowed, or considered reasonable. Used in a broader context beyond strict logic.
  3. The probable, the contingent — In the sense of simple probability, without the strict philosophical distinction from the necessary. Often synonymous with 'possible'.
  4. The suitable, the appropriate — That which is suitable or appropriate for a given situation, that which can be accepted as correct.
  5. The feasible, the achievable — That which can be accomplished or realized, that which is within the realm of possibility.
  6. The receptive, the susceptible — That which can receive something, be open to an influence or change.

Word Family

δέχ- (root of the verb δέχομαι, meaning 'to receive, accept')

The root δέχ- is a fundamental Ancient Greek root expressing the act of taking, receiving, and accepting. From it stems a rich family of words covering a wide range of meanings, from the simple physical reception of an object to the intellectual acceptance of an idea or the social welcoming of a person. This root, with the addition of prefixes, creates compound verbs that specialize the notion of reception in various directions, such as rejection (ἀποδέχομαι negatively), expectation (προσδέχομαι), or internal possibility (ἐνδέχομαι).

δέχομαι verb · lex. 730
The basic verb of the root, meaning 'to receive, accept, welcome, approve'. Widely used from Homer onwards, with both physical and abstract meanings. E.g., «δέχεται δῶρα» (receives gifts) or «δέχεται λόγους» (accepts arguments).

The act of receiving, taking, or accepting. Often refers to hospitality or ceremonial reception. E.g., «δοχὴ ξένων» (reception of strangers).

ἐνδέχομαι verb · lex. 735
The verb from which ἐνδεχόμενον is derived. It means 'to admit within itself, to allow, to be possible'. Central in Aristotelian logic for expressing possibility or contingency. E.g., «ἐνδέχεται γενέσθαι» (it is possible to happen).
ἐνδεκτικός adjective · lex. 684

Philosophical Journey

The concept of τὸ ἐνδεχόμενον, though rooted in the everyday use of the verb δέχομαι, acquired its central philosophical significance primarily with Aristotle, who systematically developed it as a fundamental category of logic and metaphysics.

5th-4th C. BCE
Presocratics and Plato
Although the word ἐνδέχομαι appears, the systematic philosophical distinction of the contingent as a separate category had not yet been fully formed. The idea of possibility and necessity was explored, but not with Aristotelian terminology.
4th C. BCE
Aristotle
Aristotle develops the concept of τὸ ἐνδεχόμενον as a central pillar of his logic (On Interpretation, Prior Analytics) and metaphysics (Metaphysics). He defines it as that which can be and not be, in contrast to the necessary and the impossible. This distinction is crucial for understanding causality and freedom.
3rd-1st C. BCE
Stoic Philosophers
The Stoics, with their emphasis on fate and necessity, often contrasted with the Aristotelian concept of the contingent. However, the debate about destiny and free will frequently referred to Aristotelian distinctions, even if to reject or reformulate them.
1st C. BCE - 2nd C. CE
Roman Period
Aristotelian logic and its categories were translated and commented upon by Roman philosophers and logicians, maintaining the central place of τὸ ἐνδεχόμενον in discussions of possibility and necessity.
3rd-6th C. CE
Late Antiquity and Neoplatonism
Neoplatonic commentators on Aristotle, such as Porphyry and Syrianus, continued to analyze and deepen the concept of τὸ ἐνδεχόμενον, integrating it into their own metaphysical systems, often with theological implications.
Byzantine Period
Byzantine Philosophy and Theology
Aristotelian logic, including the concept of τὸ ἐνδεχόμενον, remained fundamental for education and theological thought. It was used in discussions concerning divine providence, free will, and creation.

In Ancient Texts

Three characteristic passages from Aristotle, highlighting the central importance of τὸ ἐνδεχόμενον in his philosophy:

«τὸ ἐνδεχόμενον καὶ μὴ ὂν καὶ ὄν»
the contingent is both non-being and being
Aristotle, On Interpretation 9, 19a 9-10
«τὸ γὰρ ἐνδεχόμενον καὶ μὴ ἐνδεχόμενον οὐκ ἔστιν ἀεὶ τὸ αὐτό»
for the contingent and the non-contingent are not always the same
Aristotle, Prior Analytics A, 13, 32a 18-19
«τὸ ἐνδεχόμενον ἄρα ἐστὶν οὗ μὴ ἀνάγκη τὸ εἶναι, ἀλλὰ δυνατὸν καὶ μὴ εἶναι»
the contingent, therefore, is that whose being is not necessary, but it is possible also for it not to be
Aristotle, Metaphysics Θ, 4, 1047b 31-32

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (949) as ἐνδεχόμενον, but of different roots, offering a linguistic resonance of the numerical value:

ἀλλήλων
The pronoun 'one another', expressing reciprocity and interdependence. Its numerical connection to ἐνδεχόμενον may suggest the mutual relationship between possibilities or the interaction of contingencies.
