The observations and encounters of a man of solitude and few words are at once more nebulous and more intense than those of a gregarious man, his thoughts more ponderable, more bizarre and never without a hint of sadness. Images and perceptions that might easily be dismissed with a glance, a laugh, an exchange of opinions occupy him unduly; they are heightened in the silence, gain in significance, turn into experience, adventure, emotion. Solitude begets originality, bold and disconcerting beauty, poetry. But solitude can also beget perversity, disparity, the absurd and the forbidden.

In solitude the mind gains strength and learns to lean upon itself.

For what a man is in himself, what accompanies him when he is alone, what no one can give or take away, is obviously more essential to him than everything he has in the way of possessions, or even what he may be in the eyes of the world. An intellectual man in complete solitude has excellent entertainment in his own thoughts and fancies, while no amount of diversity or social pleasure, theatres, excursions and amusements, can ward off boredom from a dullard.

To go into solitude, a man needs to retire as much from his chamber as from society. I am not solitary whilst I read and write, though nobody is with me. But if a man would be alone, let him look at the stars.

The observations and encounters of a solitary, taciturn man are vaguer and at the same times more intense than those of a sociable man; his thoughts are deeper, odder and never without a touch of sadness. Images and perceptions that could be dismissed with a glance, a laugh, an exchange of opinions, occupy him unduly, become more intense in the silence, become significant, become an experience, an adventure, an emotion. Solitude produces originality, bold and astonishing beauty, poetry. But solitude also produces perverseness, the disproportionate, the absurd and the forbidden.

The more powerful and original a mind, the more it will incline towards the religion of solitude.

No man should go through life without once experiencing healthy, even bored solitude in the wilderness, finding himself depending solely on himself and thereby learning his true and hidden strength

The greater the spirit, the more one is alone.

Most great ideas spring from solitude.

Lonely courage played a part that mass obedience to the leader's command could never rival. Such courage produced heroes of the mind as well as of the battlefield, often in the same person.

It takes courage for a man to listen to his own goodness and act on it. Do we dare to be ourselves? That is that question that counts.

"I think one travels more usefully when they travel alone, because they reflect more."

(<i>Letter to John Banister, Jr.,</i> June 19, 1787)

Common experience shows how much rarer is moral courage than physical bravery. A thousand men will march to the mouth of the cannon where one man will dare espouse an unpopular cause.

For I say to you in all the sadness of conviction, that to think great thoughts you must be heroes as well as idealists. Only when you have worked alone – when you have felt around you a black gulf of solitude more isolating than that which surrounds the dying man, and in hope and in despair have trusted to your own unshaken will – then only will you have achieved. Thus only can you gain the secret isolated joy of the thinker, who knows that, a hundred years after he is dead and forgotten, men who have never heard of him will be moving to the measure of his thought – the subtle rapture of a postponed power, which the world knows not because it has no external trappings, but which to his prophetic vision is more real than that which commands an army.
