Monologue is the smoke of the internal fires of the soul.
[tr. Hapgood (1888); Phillips (1894)]

The monologue is the smoke of the inner fires of the mind.
[tr. Lavelle (2003)]

He questioned himself, answered himself, praised himself, blamed himself. You heard him in the street soliloquizing in his van. The passers-by, who have their own way of appreciating clever people, used to say, "He is an idiot."
[tr. Unknown (1869); Unknown, Authorized (1871)]

He questioned himself and answered himself; he glorified himself and insulted himself. He could be heard from the street, indulging in a monologue in his hut. The passers-by, who have their own way of appreciating men of wit, said, "he is an idiot."
[tr. Hapgood (1888)]

He questioned and answered himself; he glorified and insulted himself. He could be heard from the street talking to himself in his hut. The passers-by, who have their own way of appreciating clever people, said: "He's a fool."
[tr. Phillips (1894)]

Any one who has lived a solitary life knows how deeply seated monologue is in one's nature. Speech imprisoned longs to find a vent. To harangue space is an outlet. To talk out loud when one is alone is as it were to have a dialogue with the divinity within. It was, as is well known, a habit with Socrates; he declaimed to himself. Luther did the same.
[tr. Unknown (1869); Unknown, Authorized (1871)]

Any one who has lived alone, knows how natural monologue is. The inner word itches. Haranguing space offers a vent. Speaking aloud and alone, produces the effect of a dialogue with the god which one has within one. This was Socrates' habit, as the reader is aware. He declaimed. So did Luther.
[tr. Hapgood (1888)]

Anyone who has lived alone knows how much monologue is in nature. Inner speech itches. Haranguing the space is an outlet. Talking out loud and alone feels like a dialogue with the god within. It was, as we know, Socrates' habit. He used to talk to himself. Luther, too.
[tr. Lavelle (2003)]

[tr. Unknown (1869)]

[tr. Hapgood (1888)]

Of an unsociable and talkative disposition, not wanting to see any one, and yet wanting to talk to some one, he got out of the difficulty by talking to himself.
[tr. Phillips (1894)]

Of a fierce and talkative disposition, with a desire to see no one and a need to talk to someone, he got by by talking to himself.
[tr. Lavelle (2003)]

For he that can speak with himself; will not much need the Discourse of another.
[tr. Wase (1643)]

Whoever can converse with himself doth not need the conversation of another.
[tr. Main (1824)]
