Reason is the capacity of consciously applying logic by drawing conclusions from new or existing information, with the aim of seeking the truth.

- Reason

Within the human mind or soul (psyche), reason was described by Plato as being the natural monarch which should rule over the other parts, such as spiritedness (thumos) and the passions.

- Reason

It is a traditional model tracing its origins to ancient Greek philosophers such as Socrates, Plato, and Aristotle.

- Truth

Logic is concerned with the patterns in reason that can help tell if a proposition is true or not.

- Truth

Just as individual tables, chairs, and cars refer to objects in this world, 'tableness', 'chairness', and 'carness', as well as e. g. justice, truth, and beauty refer to objects in another world.

- Plato

In addition, the ideal city is used as an image to illuminate the state of one's soul, or the will, reason, and desires combined in the human body.

- Plato

Knowledge of facts, also referred to as propositional knowledge, is often defined as true belief that is distinct from opinion or guesswork by virtue of justification.

In the dialogue Theaetetus by the ancient Greek philosopher Plato, Socrates pondered the distinction between knowledge and true belief but rejected the JTB definition of knowledge.

Specifically, this covers cases of superstition, lucky guesses, or erroneous reasoning.

Prominent elements of his philosophy include his radical critique of truth in favor of perspectivism; a genealogical critique of religion and Christian morality and a related theory of master–slave morality; the aesthetic affirmation of life in response to both the "death of God" and the profound crisis of nihilism; the notion of Apollonian and Dionysian forces; and a characterization of the human subject as the expression of competing wills, collectively understood as the will to power.

Nietzsche objects to Euripides' use of Socratic rationalism and morality in his tragedies, claiming that the infusion of ethics and reason robs tragedy of its foundation, namely the fragile balance of the Dionysian and Apollonian.

Plato continued along this path in his dialogues, and the modern world eventually inherited reason at the expense of artistic impulses found in the Apollonian and Dionysian dichotomy.

While discussing the views of the theists among the Greek philosophers, namely Socrates, Plato and Aristotle in Al-Munqidh min ad-Dalal ("Deliverance from Error"), al-Ghazali noted that the Greek philosophers "must be taxed with unbelief, as must their partisans among the Muslim philosophers, such as Avicenna and al-Farabi and their likes."

His aim was to prove the existence of God and His creation of the world scientifically and through reason and logic.

Avicenna referred to the living human intelligence, particularly the active intellect, which he believed to be the hypostasis by which God communicates truth to the human mind and imparts order and intelligibility to nature.
