Skepticism is the sadism of embittered souls.

That there is no such thing as what philosophers call material substance, I am seriously persuaded: but if I were made to see any thing absurd or skeptical in this, I should then have the same reason to renounce this, that I imagine I have now to reject the contrary opinion.

The philosophers who wished us to have the gods for our friends rank the friendship of the holy angels in the fourth circle of society, advancing now from the three circles of society on earth to the universe, and embracing heaven itself. And in this friendship we have indeed no fear that the angels will grieve us by their death or deterioration. But as we cannot mingle with them as familiarly as with men (which itself is one of the grievances of this life), and as Satan, as we read, sometimes transforms himself into an angel of light, to tempt those whom it is necessary to discipline, or just to deceive, there is great need of God's mercy to preserve us from making friends of demons in disguise, while we fancy we have good angels for our friends; for the astuteness and deceitfulness of these wicked spirits is equalled by their hurtfulness.

Divinity reveals herself in all things... everything has Divinity latent within itself. For she enfolds and imparts herself even unto the smallest beings, and from the smallest beings, according to their capacity. Without her presence nothing would have being, because she is the essence of the existence of the first unto the last being.

For I find that even those that have sought knowledge for itself and not for benefit, or ostentation, or any practical enablement in the course of their life, have nevertheless propounded to themselves a wrong mark, namely, satisfaction, which men call truth, and not operation. For as in the courts and services of princes and states, it is a much easier matter to give satisfaction than to do the business; so in the inquiring of causes and reasons it is much easier to find out such causes as will satisfy the mind of man, and quiet objections, than such causes as will direct him and give him light to new experiences and inventions.

To suffer is to produce knowledge.

Personally, people know themselves very poorly.

As money grows, care follows it and the hunger for more.

Reason does not exist for the sake of life, but life for the sake of reason. An existence which does not of itself satisfy reason and solve all her doubts, cannot be the true one.

There is only one man who gets his own way-he who can get it single-handed; therefore freedom, not power, is the greatest good. That man is truly free who desires what he is able to perform, and does what he desires. This is my fundamental maxim. Apply it to childhood, and all the rules of education spring from it. Society has enfeebled man, not merely by robbing him of the right to his own strength, but still more by making his strength insufficient for his needs. This is why his desires increase in proportion to his weakness; and this is why the child is weaker than the man. If a man is strong and a child is weak it is not because the strength of the one is absolutely greater than the strength of the other, but because the one can naturally provide for himself and the other cannot. Thus the man will have more desires and the child more caprices, a word which means, I take it, desires which are not true needs, desires which can only be satisfied with the help of others.

The original thinking force of the universe progresses and develops itself in all possible determinations of which it is capable, just as the other original natural forces progress and assume all possible configurations. I am a particular determination of the formative force, like the plant; a particular determination of the peculiar motive force, like the animal; and in addition to this a determination of the thinking force: and the union of these three basic forces into one force, into one harmonious development, is the distinguishing characteristic of my species.

Human knowledge increases, while human irrationality stays the same. Scientific inquiry may be an embodiment of reason, but what such inquiry demonstrates is that humans are not rational animals. The fact that humanists refuse to accept the demonstration only confirms its truth.

If you could see the earth illuminated when you were in a place as dark as night, it would look to you more splendid than the moon.

A mind that has confronted ruin for years Is half or more a ruined mind.

The Quakers sent me books, from which I learnt how they had, years ago, established beyond doubt the duty for a Christian of fulfilling the command of non-resistance to evil by force, and had exposed the error of the Church's teaching in allowing war and capital punishment.

This is the worst trait of minds rendered arrogant by prosperity, they hate those whom they have injured.

The orators and the despots have the least power in their cities since they do nothing that they wish to do, practically speaking, though they do whatever they think to be best.

What is more affectionate to others than man? Yet what is more savage against them than anger?

Not to be loved is a misfortune, but it is an insult to be loved no longer.

It is a political axiom that power follows property.

What a stupendous, what an incomprehensible machine is man! Who can endure toil, famine, stripes, imprisonment and death itself in vindication of his own liberty, and the next moment, be deaf to all those motives whose powers supported him through his trial, and inflict on his fellow men a bondage, one hour of which is fraught with more misery than ages of that which he rose in rebellion to oppose.

If you do the job in a principled way, with diligence, energy and patience, if you keep yourself free of distractions, and keep the spirit inside you undamaged, as if you might have to give it back at any moment- If you can embrace this without fear or expectation-can find fulfillment in what you're doing now, as Nature intended, and in superhuman truthfulness (every word, every utterance)-then your life will be happy.

When Fortune flatters, she does it to betray.

The mind must not be forced; artificial and constrained manners fill it with foolish presumption, through unnatural elevation and vain and ridiculous inflation, instead of solid and vigorous nutriment.

It is not the pleasure of curiosity, nor the quiet of resolution, nor the raising of the spirit, nor victory of wit, nor faculty of speech that are the true ends of knowledge, but it is a restitution and reinvesting, in great part, of man to the sovereignty and power, for whensoever he shall be able to call the creatures by their true names, he shall again command them.

It seems as if the female spirit of the world were mourning everlastingly over blessings, not lost, but which she has never had, and which, in her discouragement she feels that she never will have, they are so far off.

Genuine religion is not about speculating about God or the soul or about what happened in the past or will happen in the future; it cares only about one thing-finding out exactly what should or should not be done in this lifetime.

No furniture so charming as books.

You ask if I mean to publish anything on the subject of a letter of mine to my friend Charles Thompson? Certainly not. I write nothing for publication, and last of all things should it be on the subject of religion. On the dogmas of religion as distinguished from moral principles, all mankind, from the beginning of the world to this day, have been quarrelling, fighting, burning and torturing one another, for abstractions unintelligible to themselves and to all others, and absolutely beyond the comprehension of the human mind. Were I to enter on that arena, I should only add an unit to the number of Bedlamites.

Pascal is called the founder of modern probability theory. He earns this title not only for the familiar correspondence with Fermat on games of chance, but also for his conception of decision theory, and because he was an instrument in the demolition of probabilism, a doctrine which would have precluded rational probability theory.

I have just discovered that without her father's consent this sweet, trusting, gullible six-year-old is being sent, for weekly instruction, to a Roman Catholic nun. What chance has she?

The evolutionary urge drives man to seek for intenser forms of fulfillment, since his basic urge is for more life, more consciousness, and this contentment has an air of stagnation that the healthy mind rejects. (This recognition lies at the centre of my own 'outsider theory': that there are human beings to whom comfort means nothing, but whose happiness consists in following an obscure inner-drive, an 'appetite for reality'.)

In the ceremonies of the public execution, the main character was the people, whose real and immediate presence was required for the performance.

I find that even Eminent Writers (such as Raymund Lully, Paracelsus, and others) do so abuse the termes they employ, that as they will now and then give divers things one name, so they will oftentimes give one thing, many Names; and some of them (perhaps) such, as do much more properly signifie some Distinct Body of another kind; nay even in Technical Words or Termes of Art, they refrain not from this Confounding Liberty; but will, as I have Observ'd call the same Substance, sometimes the Sulphur, and Sometimes the Mercury, of a Body.

When we cannot be delivered from ourselves, we delight in devouring ourselves.

A prince who is not wise himself will never take good advice.

I hold it, that a little rebellion, now and then, is a good thing, and as necessary in the political world as storms in the physical.

It is difficult, it is impossible to believe that the Good Lord - "Our Father" - had a hand in the scandal of creation. Everything suggests that He took no part in it, that it proceeds from a god without scruples, a feculent god. Goodness does not create, lacking imagination; it takes imagination to put together a world, however botched. At the very least, there must be a mixture of good and evil in order to produce an action or a work.

A created thing is never invented and it is never true: it is always and ever itself.

Purity is for man, next to life, the greatest good that parity is procured by the Law of Mazda to him who cleanses his own self with Good Thoughts, Words, and Deeds.

Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it.

The bow too tensely strung is easily broken.

For it is the same thing that can be thought and that can be.

Speed, it seems to me, provides the one genuinely modern pleasure.

Evil destroyeth itself.

Everywhere and at all times it is in thy power piously to acquiesce in thy present condition, and to behave justly to those who are about thee, and to exert thy skill upon thy present thoughts, that nothing shall steal into them without being well examined.

Dissimulation is innate in woman, and almost as much a quality of the stupid as of the clever.

How many worthy men have we seen survive their own reputation!
