Now I want you to tell me truly whether virtue is one whole, of which justice and temperance and holiness are parts; or whether all these are only the names of one and the same thing: that is the doubt which still lingers in my mind.

“Now I want you to tell me truly whether virtue is one whole, of which justice and temperance and holiness are parts; or whether all these are only the names of one and the same thing: that is the doubt which still lingers in my mind.”

Plato · Protagoras · 4th century BCE

Voice: Dialogue speaker · Socrates

Meaning & context

Socrates challenges Protagoras to clarify whether moral excellences such as justice, temperance and holiness make up different parts of a single virtue or name the same property. The question tests the structure of virtue rather than giving the reader an easy definition. Protagoras proposes an analogy with distinct parts of a face, and their discussion goes on to scrutinize the claim.

Source details

Plato, Protagoras, approximately Stephanus 329c–d; Socrates asks Protagoras about the unity of virtue after the sophist describes civic instruction and the acquisition of good character. Protagoras, not Socrates, answers that its qualities are distinct parts. Exact sentence from Benjamin Jowett English, Project Gutenberg #1591, in the dialogue proper after the opening philosophical and mythic arguments, not in translator commentary.

And thus we arrive at the conclusion that virtue is either wholly or partly wisdom?

“And thus we arrive at the conclusion that virtue is either wholly or partly wisdom?”

Plato · Meno · 4th century BCE

Voice: Dialogue speaker · Socrates

Meaning & context

Socrates arrives at a conditional suggestion that a good character may depend wholly or partly on wisdom. His question follows a discussion of how judgment guides courage and other qualities toward good outcomes. It is not a final definition: he soon reopens the question by doubting whether virtue can be taught and whether suitable teachers exist.

Source details

Plato, Meno, approximately Stephanus 89a; Socrates is questioning Meno after connecting the usefulness of virtues with wise guidance. The conclusion is provisional and is challenged shortly afterwards when they examine the absence of recognized teachers of virtue. Exact complete sentence in Benjamin Jowett English, Project Gutenberg #1643, dialogue proper (not translator introduction); the historical Plato is not the speaking character.

A simple thing enough; just what is commonly said, that a man should be temperate and master of himself, and ruler of his own pleasures and passions.

“A simple thing enough; just what is commonly said, that a man should be temperate and master of himself, and ruler of his own pleasures and passions.”

Plato · Gorgias · 4th century BCE

Voice: Dialogue speaker · Socrates

Meaning & context

Socrates describes moderation as governing one’s own appetite and impulses rather than merely exercising power over other people. Callicles immediately challenges this view and praises satisfying desires without restraint. The passage is an argument in a dispute about happiness and the good life, not modern evidence about psychology or a claim that feelings should be suppressed.

Source details

Plato, Gorgias, approximately Stephanus 491d–e, Socrates answering Callicles’s question about ruling oneself. Callicles promptly disputes the value of temperance. Full sentence in Benjamin Jowett’s English translation, Project Gutenberg #1672, within the Gorgias dialogue proper (not Jowett’s introductory essay). Socrates is the local dramatic speaker; the line is not Plato’s autobiographical speech. An ancient ethical argument, not experimental mental-health evidence.

And ought not the rational principle, which is wise, and has the care of the whole soul, to rule, and the passionate or spirited principle to be the subject and ally?

Plato · The Republic · 4th century BCE

Voice: Dialogue speaker · Socrates

Meaning & context

Socrates argues that self-government involves a rational faculty attending to the whole person while spirited impulses support its judgment. The passage is a question within his analogy between a well-ordered city and the three parts of the soul. It does not mean that all emotion should be suppressed or that Plato established a modern psychological theory.

Source details

Plato, The Republic, Book IV, approximately 441e–442a; Socrates addressing Glaucon while contrasting the rational, spirited and appetitive parts of the soul. Exact sentence from Benjamin Jowett English, Project Gutenberg #1497, Book IV main dialogue (not introductory editorial matter). The premise belongs to an ancient account of the soul and remains open to philosophical interpretation; not clinical or neuroscientific evidence.

Plato · Philebus · 4th century BCE

Voice: Dialogue speaker · Socrates

Meaning & context

Socrates invokes earlier thinkers in a discussion of whether intelligence helps order the cosmos. The claim concerns an ancient metaphysical account of mind as a cause, not the modern sense of an individual person’s mental health or an experimentally settled account of the universe.

Source details

Plato, Philebus, approximately 30c–d; Socrates addressing Protarchus amid the argument that reason or mind belongs with the ordering cause rather than with limitless pleasure. Benjamin Jowett English, Project Gutenberg #1744, dialogue text.

And thought is best when the mind is gathered into herself and none of these things trouble her—neither sounds nor sights nor pain nor any pleasure,—when she takes leave of the body, and has as little as possible to do with it, when she has no bodily sense or desire, but is aspiring after true being?

Plato · Phaedo · 4th century BCE

Voice: Dialogue speaker · Socrates

Meaning & context

Socrates argues that philosophical reflection is clearest when bodily sensations do not distract the soul from its inquiry. This belongs to his metaphysical case about knowledge, body and soul on the day of his death; it should not be confused with a modern scientific finding about the brain or with a general prohibition on sensory experience.

Source details

Plato, Phaedo, approximately 65c–d; Socrates speaking with Simmias about the philosopher’s pursuit of true being and the limits of bodily perception. Benjamin Jowett English, Project Gutenberg #1658, dramatic text (not the editorial introduction).
