ΚΑΡΔΙΑ

LEXARITHMOS 136

The heart (καρδία), in ancient Greek thought and especially in the Judeo-Christian tradition, was not merely the biological organ, but the center of human existence: the seat of emotions, will, thought, and moral consciousness. Its lexarithmos (136) suggests a completeness and a complex internal structure, reflecting its multifaceted significance.

Definition

According to the Liddell-Scott-Jones Lexicon, καρδία is primarily "the heart, the organ of life," but immediately extends to metaphorical uses such as "the seat of feelings, mind, soul." Its significance far exceeds its anatomical function, making it a central point of reference for human inner life.

In the Homeric era, καρδία (or κραδία) is often used in parallel with θυμός to denote the seat of emotions, passions, and thought. There is no clear distinction between rational and emotional functions, with the heart considered the organ through which humans experience and perceive the world.

In philosophical thought, although Plato and Aristotle developed more complex theories of the soul and its functions (rational, spirited, appetitive), the heart retained its importance as a vital center. In the Judeo-Christian tradition, particularly in the Septuagint translation, καρδία becomes the equivalent of the Hebrew "lev" (לֵב), signifying the deepest center of the personality, the seat of will, moral choice, faith, and the relationship with God. It is the place where God writes His law and where man is called to be purified to see Him.

Etymology

καρδία ← Proto-Indo-European *ḱr̥d- / *ḱḗr (heart)
The word καρδία derives from the Proto-Indo-European root *ḱr̥d- or *ḱḗr, which denotes the heart as the central organ. This root has given rise to a plethora of cognate words in many Indo-European languages, underscoring the ancient and fundamental importance of the concept.

Cognate words in ancient Greek include the poetic form κραδία and κῆρ (the inner part of the heart, the soul). In other languages, we find the Latin cor (hence English cordial), the English heart, the German Herz, the Sanskrit hṛd, and the Russian сердце (serdtse), all with the same primary meaning.

Philosophical Journey

The concept of the heart has traversed a rich journey in ancient thought, evolving from a mere biological organ to a symbol of the human soul and spiritual center.

8th-7th C. BCE (Homeric Era)
Homeric Thought
In Homer's epics, καρδία (or κραδία) and θυμός are often synonymous, denoting the seat of emotions, passions, and thoughts. There is no clear distinction between rational and emotional functions.
5th-4th C. BCE (Classical Philosophy)
Plato and Aristotle
Plato and Aristotle, though developing more complex theories of the soul, recognized the heart as a vital organ. Aristotle, in his treatise "On the Soul," considered it the center of sensation and movement, though not the seat of reason.
3rd-1st C. BCE (Septuagint Translation)
Old Testament (LXX)
In the Greek translation of the Old Testament, καρδία is used to render the Hebrew "lev" (לֵב), which symbolizes the deepest center of human personality, the seat of will, intellect, moral consciousness, and faith.
1st C. CE (New Testament)
Christian Theology
The heart retains and strengthens its theological significance. It is the place where faith dwells, where God writes His law, and where man is called to be purified to see God (Matt. 5:8). It symbolizes the source of good or evil deeds.
2nd-5th C. CE (Patristic Thought)
Church Fathers
The Church Fathers, such as Basil the Great and Gregory of Nyssa, further developed the concept of the "heart" as the spiritual center of man, the seat of "noetic prayer" and the place of encounter with God.

In Ancient Texts

Three significant passages that highlight the multifaceted meaning of the heart in ancient Greek and Judeo-Christian literature.

«Καρδίαν καθαρὰν κτίσον ἐν ἐμοί, ὁ Θεός, καὶ πνεῦμα εὐθὲς ἐγκαίνισον ἐν τοῖς ἐγκάτοις μου.»
“Create in me a clean heart, O God, and renew a right spirit within me.”
Psalms 50:12 (LXX)
«Μακάριοι οἱ καθαροὶ τῇ καρδίᾳ, ὅτι αὐτοὶ τὸν Θεὸν ὄψονται.»
“Blessed are the pure in heart, for they shall see God.”
Gospel of Matthew 5:8
«ἀλλὰ Διὸς νοῦς ἐστιν ἀμήχανος οὐδὲ δόκησις ἐξαπατᾷ, οὐδὲ μὴν καρδίην ἔχει.»
“But the mind of Zeus is unapproachable, nor does seeming deceive him, nor indeed does he have a heart.”
Hesiod, Theogony 533
