Jealousy is a painful passion; yet without some share of it, the agreeable affection of love has difficulty to subsist in its full force and violence.

The chief and most confounding objection to excessive skepticism, that no durable good can ever result from it; while it remains in its full force and vigor. We need only ask such a skeptic, what his meaning is? And what he proposes by all these curious researches? He is immediately at a loss, and knows not what to answer.

We may begin with considering a-new the nature and force of sympathy. The minds of all men are similar in their feelings and operations, nor can any one be actuated by any affection, of which all others are not, in some degree, susceptible. As in strings equally bound up, the motion of one communicates itself to the rest; so all the affections readily pass from one person to another, and beget correspondent movements in every human creature.

An idea, to be suggestive, must come to the individual with the force of a revelation.

Our business in life is not to get ahead of others but to get ahead of ourselves - to break our own records, to outstrip our yesterdays by our today, to do our work with more force than ever before.

Injuries may be atoned for, and forgiven; but insults admit of no compensation. They degrade the mind in its own esteem, and force it to recover its level by revenge.

No man can force the harp of his own individuality into the people’s heart; but every man may play upon the chords of the people’s heart, who draws his inspiration from the people’s instinct.

All duties are matter of conscience, with this restriction that a superior obligation suspends the force of an inferior one.

If we have need of a strong will in order to do good, it is more necessary still for us in order not to do evil; from which it often results that the most modest life is that where the force of will is most exercised.

Through a fatality inseparable from human nature, moderation in great men is very rare: and as it is always much easier to push on force in the direction in which it moves than to stop its movement, so in the superior class of the people, it is less difficult, perhaps, to find men extremely virtuous, than extremely prudent.

There is nothing a man can less afford to leave at home than his conscience or his good habits; for it is not to be denied that travel is, in its immediate circumstances, unfavorable to habits of self-discipline, regulation of thought, sobriety of conduct, and dignity of character. Indeed, one of the great lessons of travel is the discovery how much our virtues owe to the support of constant occupation, to the influence of public opinion, and to the force of habit; a discovery very dangerous, if it proceed from an actual yielding to temptations resisted at home, and not from a consciousness of increased power put forth in withstanding them.

The force, the mass of character, mind, heart or soul that a man can put into any work is the most important factor in that work.

Vigilance in watching opportunity; tact and daring in seizing upon opportunity; force and persistence in crowding opportunity to its utmost possible achievement - these are the martial virtues which must command success.

Our purpose is to consciously, deliberately evolve toward a wise, more liberated and luminous state of being. Deep down, all of us are probably aware that some kind of mystical evolution is our true task. Yet we suppress the notion with considerable force because to admit to it is to admit that most of our political gyrations, religious dogmas, social ambitions and financial ploys are not merely counterproductive but trivial. Our mission is to jettison those pointless preoccupations and take on once again the primordial cargo of inexhaustible ecstasy.

Marriage is not a union merely between two creatures - it is a union between two spirits; and the intention of that bond is to perfect the nature of both, by supplementing their deficiencies with the force of contrast, giving to each sex those excellencies in which it is naturally deficient; to the one, strength of character and firmness of moral will; to the other, sympathy, meekness, tenderness; and just so solemn and glorious as these ends are for which the union was intended, just so terrible are the consequences if it be perverted and abused; for there is no earthly relationship which has so much power to ennoble and exalt.

The less reasonable a cult is, the more men seek to establish it by force.

"Free thought" means thinking freely... To be worthy of the name [freethinker] he must be free of two things: the force of tradition and the tyranny of his own passions. No one is completely free from either, and in the measure of a man's emancipation he deserves to be called a free thinker.

Education is, as a rule, the strongest force on the side of what exists and against fundamental change: threatened institutions, while they are still powerful, possess themselves of the educational machine, and instill a respect for their own excellence into the malleable minds of the young.

Ethical metaphysics is fundamentally an attempt, however disguised, to give legislative force to our own wishes.

Without the consent of the world, a scandal doth not go deep; it is only a slight stroke upon the injured party, and returneth with the greater force upon those that gave it.
