ΛΟΓΟΣ ΑΠΟΔΕΙΚΤΙΚΟΣ
Demonstrative discourse, or λόγος ἀποδεικτικός, stands as the cornerstone of scientific knowledge in ancient Greek philosophy, particularly as elaborated by Aristotle. It is not merely a discussion but a rigorous process of reasoning that leads to undeniable conclusions, establishing science (ἐπιστήμη) as the knowledge of "why." Its lexarithmos (1163) underscores the complexity and completeness of the concept.
REPORT ERRORDefinition
The "λόγος ἀποδεικτικός" refers to a type of discourse or argument aimed at demonstration, i.e., the production of certain and necessary knowledge. In classical Greek philosophy, and especially in Aristotelian logic, this term is technical and denotes the scientific method through which conclusions are derived from true and primary premises. It is the discourse that "shows from" (ἀπο-δείκνυμι) the truth of things.
It differs from dialectical or rhetorical discourse, which rely on probable or persuasive premises. Demonstrative discourse, in contrast, operates on the basis of principles that are known beforehand and true, leading to conclusions that are also necessarily true. This process is the core of "ἀπόδειξις" and the "συλλογισμός" that leads to "ἐπιστήμη."
Aristotle, in his "Analytics," extensively analyzes the structure and preconditions of demonstrative discourse, making it the foundation of scientific knowledge. For him, science is the knowledge of causes, and demonstrative discourse is the means for revealing these causes.
Etymology
From the root "λογ-" derive many words related to thought, speech, and calculation, such as "λογικός" (logical), "λογική" (logic), "συλλογισμός" (syllogism), "λογίζομαι" (to reckon). From the root "δεικ-" and the verb "δείκνυμι" arise words like "ἀπόδειξις" (demonstration), "ἐπίδειξις" (display), "δεῖγμα" (sample). The "λόγος ἀποδεικτικός" is a compound expression that integrates the function of logical thought and the clear manifestation of truth.
Main Meanings
- Logical Demonstration, Scientific Reasoning — The primary meaning in Aristotelian philosophy, referring to the process of deriving necessary conclusions from true premises (Aristotle, 'Posterior Analytics').
- Demonstrative Argument — Any type of discourse or argument aimed at substantiating and proving a thesis, in contrast to dialectical or rhetorical discourse.
- Scientific Knowledge — The knowledge acquired through demonstration, 'episteme' according to Aristotle, which is knowledge of causes and necessary truths.
- Indisputable Truth — The outcome of demonstration, a conclusion that cannot be challenged due to the rigor of the reasoning process.
- Method of Substantiation — The methodology used for presenting and establishing a position with logical arguments and evidence.
- Rhetorical Genre — In a broader context, it refers to a type of rhetorical discourse that employs demonstrative evidence, albeit with less rigor than the philosophical concept.
Word Family
log- (from the verb λέγω) and deik- (from the verb δείκνυμι)
