ΠΡΟΓΝΩΣΙΣ

LEXARITHMOS 1513

Prognosis, a term deeply rooted in ancient Greek thought, describes the ability or act of knowing something before it happens. From the medicine of Hippocrates, where it was vital for assessing the course of an illness, to the philosophy of the Stoics, who examined divine foreknowledge and fate, the concept of prognosis permeates many fields. Its lexarithmos (1513) suggests a complex knowledge that transcends the present.

Definition

According to the Liddell-Scott-Jones Lexicon, prognosis (πρόγνωσις) is primarily "foreknowledge, foresight, presentiment." The word is compounded from the prefix "pro-" (before) and the noun "gnosis" (knowledge), thereby denoting the knowledge of future events or the ability to know something in advance. Its significance is central to both medicine and philosophy.

In medicine, prognosis, as developed by Hippocrates and his followers, concerned the estimation of the probable course and outcome of a disease. Hippocrates, in his work *Prognostikon*, emphasizes the importance of prognosis for the physician, not only to gain the patient's trust but also to guide treatment. The ability to predict the evolution of an illness was considered a mark of high medical skill.

Philosophically, prognosis is linked to the concepts of fate (μοῖρα), destiny (εἱμαρμένη), and divine providence (πρόνοια). The Stoics, in particular, extensively discussed divine prognosis, arguing that the gods possess complete knowledge of future events, which raises questions about human free will. Prognosis was not merely a prediction but often a knowledge stemming from a deeper understanding of the world's order.

Beyond medicine and philosophy, prognosis was also used in a more general context for prediction and presentiment, whether through dreams, omens, or simple empirical observation. The word underscores the human desire to transcend the limitations of the present and gain knowledge about the future.

Etymology

prognosis ← pro- (before) + gnosis (knowledge) ← gignōskō (to know). The root gno-/gnō- is an Ancient Greek root belonging to the oldest stratum of the language.
The word "prognosis" is a compound noun, formed from the prefix "pro-", indicating "before" or "in advance," and the noun "gnosis," which derives from the verb "gignōskō" ("to know, perceive"). This compound signifies knowledge that precedes the event or experience. The root gno-/gnō- is fundamental in the Greek language, generating a wide range of words related to knowledge, perception, and judgment.

The word family of the root gno-/gnō- is rich and includes core concepts of Greek thought. From the verb gignōskō are derived nouns such as gnōsis (the act or result of knowing), gnōmē (judgment, opinion), and adjectives like gnōstos (that which is known). With the addition of prefixes, compound words are created that specialize the meaning of knowledge, such as diagnosis (knowledge through), epignōsis (full knowledge), and, of course, prognosis (prior knowledge).

Main Meanings

  1. Foreknowledge, Prescience — The general concept of knowing an event before it occurs.
  2. Medical Prediction — The estimation of the course and outcome of a disease, as in Hippocrates.
  3. Divine Foreknowledge — The knowledge of future events by the gods or a higher power, particularly in Stoic philosophy.
  4. Prediction, Prophecy — The act of announcing future events, often based on signs or omens.
  5. Warning, Premonition — A sign or symptom indicating what is about to happen.
  6. Prior Perception — The ability to perceive something before its full manifestation.

Word Family

gno- / gnō- (root of the verb gignōskō, meaning "to know, perceive")

The root gno-/gnō- constitutes one of the oldest and most productive nuclei of the Greek language, from which an extensive network of words develops, revolving around the concept of knowledge, perception, judgment, and recognition. This root, belonging to the oldest stratum of the language, expresses both the act of acquiring knowledge and the result of this process. Through prefixes and suffixes, the basic meaning is specialized, covering a wide range of cognitive functions, from simple recognition to deep understanding and prediction.

γιγνώσκω verb · lex. 1886
The fundamental verb of the root, meaning "to know, perceive, learn." It forms the basis for all words in the family related to the cognitive process. Widely used from Homer to the New Testament.
γνῶσις ἡ · noun · lex. 1263
The noun denoting the act of knowing, knowledge itself, or perception. It forms the second component of "prognosis" and is a central concept in philosophy, especially in Plato and Gnosticism.
προγιγνώσκω verb · lex. 2136
The verb corresponding to "prognosis," meaning "to know beforehand, to foresee." Used by Hippocrates for medical prediction and by philosophers for divine foreknowledge.
διάγνωσις ἡ · noun · lex. 1278
Knowledge acquired "through" (διά) observation and analysis, especially in medicine. "Diagnosis" is the identification of a disease from its symptoms, in contrast to "prognosis" which concerns its progression.
ἐπίγνωσις ἡ · noun · lex. 1378
Full, accurate, or deep knowledge, recognition. It often carries an ethical or spiritual connotation, implying knowledge that leads to transformation, as in the New Testament (e.g., "εἰς ἐπίγνωσιν ἀληθείας").
ἀγνωσία ἡ · noun · lex. 1065
The lack of knowledge, ignorance. Formed with the privative "a-" and represents the opposite state of knowledge. In philosophy, "agnosia" can be either simple ignorance or a conscious admission of the limits of human knowledge.
γνώμη ἡ · noun · lex. 901
Judgment, opinion, decision. Derived from the same root, it denotes the cognitive function of forming an opinion or conclusion. In Thucydides, "gnome" often refers to political decisions.
γνωστός adjective · lex. 1623
That which is known, recognizable, manifest. It describes the quality of having knowledge about something or someone. In everyday usage, it refers to familiar persons or things.

Philosophical Journey

The concept of prognosis, though the word itself is not always present, runs through Greek thought from the earliest times, evolving from empirical observation into a profound philosophical and theological concept.

6th-5th C. BCE (Presocratics)
Presocratic Thought
Although the word "prognosis" is not systematically used, Presocratic philosophers, such as Heraclitus, dealt with the concept of necessity and the order of the cosmos, laying the groundwork for the idea of the predictability of events.
5th-4th C. BCE (Hippocrates)
Medical Science
Hippocrates and his medical school established prognosis as a fundamental principle of medical science. The work *Prognostikon* is a classic text describing the importance of predicting the course of diseases.
4th C. BCE (Plato & Aristotle)
Classical Philosophy
Plato and Aristotle examined knowledge and the possibility of knowing the future, often in relation to mantic art or divine intervention, albeit with different approaches to causality and necessity.
3rd C. BCE - 3rd C. CE (Stoics)
Stoic Philosophy
Stoic philosophers extensively developed the theory of divine foreknowledge (πρόνοια) and fate (εἱμαρμένη), arguing that all events are predetermined and known in advance by the gods, which influenced their ethics and worldview.
1st C. BCE - 1st C. CE (Koine Greek & New Testament)
Hellenistic and Early Christian Period
The word is used in Koine Greek and occasionally in the New Testament (e.g., Acts 2:23) to denote divine foreknowledge of events, especially in relation to the plan of salvation.
2nd-5th C. CE (Patristic Theology)
Patristic Theology
The Church Fathers addressed the relationship between divine foreknowledge and human free will, attempting to reconcile God's omniscience with human moral responsibility.

In Ancient Texts

The significance of prognosis is highlighted in texts spanning medicine, philosophy, and theology.

«Περὶ δὲ τῶν νοσημάτων, ὅκως ἂν ἔχῃ, καὶ ὅτι ἂν γένηται, καὶ ὅτι ἂν γένηται ἐκ τούτων, προγιγνώσκειν.»
“Concerning diseases, how they will be, and what will happen, and what will result from these, one must foreknow.”
Hippocrates, Prognostikon, 1
«τὸ γὰρ προγιγνώσκειν τὰ μέλλοντα καὶ τὸ προλέγειν ὅσα ἂν μέλλῃ γίνεσθαι, τοῦτο μάλιστα θεῖόν ἐστιν.»
“For to foreknow future things and to foretell all that is to happen, this is especially divine.”
Plato, Republic, 496c
«τοῦτον τῇ ὡρισμένῃ βουλῇ καὶ προγνώσει τοῦ Θεοῦ ἔκδοτον διὰ χειρῶν ἀνόμων προσπήξαντες ἀνείλετε.»
“This man, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men.”
Acts of the Apostles, 2:23
