Whoever finishes a revolution only halfway, digs his own grave.

In every man sleeps a prophet, and when he wakes there is a little more evil in the world.

Organic life, we are told, has developed gradually from the protozoon to the philosopher, and this development, we are assured, is indubitably an advance. Unfortunately it is the philosopher, not the protozoon, who gives us this assurance.

Fortunate is he who has acquired a wealth of divine understanding, but wretched the one whose interest lies in shadowy conjectures about divinities.

In so far as words are not used obviously to calculate technically relevant probabilities or for other practical purposes, ... they are in danger of being suspect as sales talk of some kind.

Those who claim to care about the wellbeing of human beings and the preservation of our environment should become vegetarians for that reason alone. They would thereby increase the amount of grain available to feed people elsewhere, reduce pollution, save water and energy, and cease contributing to the clearing of forests; moreover, since a vegetarian diet is cheaper than one based on meat dishes, they would have more money available to devote to famine relief, population control, or whatever social or political cause they thought most urgent. ... when nonvegetarians say that "human problems come first" I cannot help wondering what exactly it is that they are doing for human beings that compels them to continue to support the wasteful, ruthless exploitation of farm animals.

The will of man has no power whatever over his opinions; he must, and ever did, and ever will, believe what has been, is, or may be impressed on his mind by his predecessors, and the circumstances which surround him.

The rush to California, for instance, and the attitude, not merely of merchants, but of philosophers and prophets, so called, in relation to it, reflect the greatest disgrace on mankind. That so many are ready to live by luck, and so get the means of commanding the labor of others less lucky, without contributing any value to society!

In these downbeat times, we need as much hope and courage as we do vision and analysis; we must accent the best of each other even as we point out the vicious effects of our racial divide and pernicious consequences of our maldistribution of wealth and power. We simply cannot enter the twenty-first century at each other's throats, even as we acknowledge the weighty forces of racism, patriarchy, economic inequality, homophobia, and ecological abuse on our necks. We are at a crucial crossroad in the history of this nation--and we either hang together by combating these forces that divide and degrade us or we hang separately. Do we have the intelligence, humor, imagination, courage, tolerance, love, respect, and will to meet the challenge? Time will tell. None of us alone can save the nation or world. But each of us can make a positive difference if we commit ourselves to do so.

One of the most exquisite pleasures of human love - to serve the loved one without his knowing it - is only possible, as regards the love of God, through atheism.

These left me in no doubt that something was trying to communicate with us, but that direct communication would be counterproductive. It seemed to be an important part of the scheme to create a sense of mystery.

In the name of national security, the Commission's hearings were held in secret, thereby continuing the policy which has marked the entire course of the case. This prompts my second question: If, as we are told, Oswald was the lone assassin, where is the issue of national security? Indeed, precisely the same question must be put here as was posed in France during the Dreyfus case: If the Government is so certain of its case, why has it conducted all its inquiries in the strictest secrecy? "

In formal logic, a contradiction is the signal of a defeat; but in the evolution of real knowledge it marks the first step in progress towards a victory.

Science fiction may be defined as that branch of literature which deals with the response of human beings to advances in science and technology. Actual change in science and technology, occurring quickly enough and striking deeply enough to affect a human being in the course of his normal lifetime, is a phenomenon peculiar to the world only since the Industrial Revolution ... The first well-known writer who responded to this new factor in human affairs by dealing regularly with science fiction, by studying the effect of additional scientific advance upon mankind ... was Jules Verne. In the English language, the early master was H. G. Wells. Between them, they laid the foundation for every theme upon which science fiction writers have been ringing variations ever since.

It is a royal privilege to do good and be ill spoken of.

Many conflicts within Third World countries are related to the practice of exploiting resources faster than nature can renew them or diverting them away from where people need them. Dams in every society have become major sources of conflict. As water scarcity grows, neighbors, families turn against each other.

What do I care about Jupiter? Justice is a human issue, and I do not need a god to teach it to me.

When Confucius and the Indian Scriptures were made known, no claim to monopoly of ethical wisdom could be thought of... It is only within this century [the 1800 's] that England and America discovered that their nursery tales were old German and Scandinavian stories; and now it appears that they came from India, and are therefore the property of all the nations.

Regarding the plan to collect my writings in volumes, I am quite cool and not at all eager about it because, roused by a Saturnian hunger, I would rather see them all devoured. For I acknowledge none of them to be really a book of mine, except perhaps the one On the Bound Will and the Catechism.

The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes.) The real foundations of his enquiry do not strike a man at all. Unless that fact has at some time struck him. - And this means: we fail to be struck by what, once seen, is most striking and most powerful.

I am as desirous of being a good neighbor as I am of being a bad subject.

There is one story left, one road: that it is. And on this road there are very many signs that, being, is uncreated and imperishable, whole, unique, unwavering, and complete.

The great end of all human industry, is the attainment of happiness. For this were arts invented, sciences cultivated, laws ordained, and societies modelled, by the most profound wisdom of patriots and legislators.

I am not sure but I should betake myself in extremities to the liberal divinities of Greece, rather than to my country's God. Jehovah, though with us he has acquired new attributes, is more absolute and unapproachable, but hardly more divine, than Jove. He is not so much of a gentleman, not so gracious and catholic, he does not exert so intimate and genial an influence on nature, as many a god of the Greeks.

It is absurd to excite reason against the primary postulates of pure time, as, for example, continuity, etc., since they follow from laws prior and superior to which nothing is found, and since reason herself in the use of the principle of contradiction cannot dispense with the support of this concept, so primitive and original is it.

I shall develop the thesis that anyone acting communicatively must, in performing any speech act, raise universal validity claims and suppose that they can be vindicated.

It is, I think, safe to say that nothing was more alien to the minds of the scientists, who brought about the most radical and most rapid revolutionary process the world has ever seen, than any will to power. Nothing was more remote than any wish to 'conquer space' and to go to the moon. It was indeed their search for 'true reality' that led them to lose confidence in appearances, in the phenomena as they reveal themselves of their own accord to human sense and reason. They were inspired by an extraordinary love of harmony and lawfulness which taught them that they would have to step outside any merely given sequence or series of occurrences if they wanted to discover the overall beauty and order of the whole, that is, the universe.

To have good sense, is the first principle and fountain of writing well.

A house sold by A to B does not wander from one place to another, although it circulates as a commodity.

In all affairs - love, religion, politics, or business - it's a healthy idea, now and then, to hang a question mark on the things you have long taken for granted.

While they denounce as subversive anarchy signs of independent thought, of thinking for themselves on the part of others lest such thought disturb the conditions by which they profit, they think quite literally for themselves, that is of themselves.

The division of Philosopher and Poet is only apparent, and to the disadvantage of both. It is a sign of disease, and of a sickly constitution.

To live classically and to realize antiquity practically within oneself is the summit and goal of philology.

Here then is what we understand by these words: "the equalization of the classes." It would perhaps have been better to say suppression of the classes, the unification of society by the abolition of economic and social inequality. But we have also demanded the equalization of the individuals, and it is there especially that we attract all the thunderbolts of outraged eloquence from our adversaries. One has made use of that part of our proposition to prove in a conclusive manner that we are nothing but communists.

And then one babbles - 'if only I could bear it, or the worst of it, or any of it, instead of her.' But one can't tell how serious that bid is, for nothing is staked on it. If it suddenly became a real possibility, then, for the first time, we should discover how seriously we had meant it. But is it ever allowed? It was allowed to One, we are told, and I find I can now believe again, that He has done vicariously whatever can be done. He replies to our babble, 'you cannot and dare not. I could and dared.'

The more man ascends through the past, and the more he launches into the future, the greater he will be, and all these philosophers and ministers and truth-telling men who have fallen victims to the stupidity of nations, the atrocities of priests, the fury of tyrants, what consolation was left for them in death? This: That prejudice would pass, and that posterity would pour out the vial of ignominy upon their enemies. O Posterity! Holy and sacred stay of the unhappy and the oppressed; thou who art just, thou who art incorruptible, thou who findest the good man, who unmaskest the hypocrite, who breakest down the tyrant, may thy sure faith, thy consoling faith never, never abandon me!

There are people with whom everything they consider a means turns mysteriously into an end.

The total victimization of the individual that takes place is encouraged for the specific benefit of the industrial and political bureaucracy. It therefore cannot be justified on the ground of the individual's true interest. National Socialist ideology simply states that true human existence consists in unconditional sacrifice, that it is of the essence of the individual's life to abbey and to serve-'service which never comes to an end because service and life coincide.'

In fact, contempt for happiness is usually contempt for other people's happiness, and is an elegant disguise for hatred of the human race.

There are men who astonish and delight, men who instruct and guide. Some men's words I remember so well that I must often use them to express my thought. Yes, because I perceive that we have heard the same truth, but they have heard it better.

Coulson Turnbull in Life and Teachings of Giordano Bruno : Philosopher, Martyr, Mystic 1548 - 1600 (1913), p. 41

The human soul has need of disciplined participation in a common task of public value, and it has need of personal initiative within this participation. The human soul has need of security and also of risk. The fear of violence or of hunger or of any other extreme evil is a sickness of the soul. The boredom produced by a complete absence of risk is also a sickness of the soul.

That which exercises reason is more excellent than that which does not exercise reason; there is nothing more excellent than the universe, therefore the universe exercises reason.

The cult of the Virgin, Mariolatry, which by the gradual elevation of the divine element in the Virgin has led almost to her deification, answers merely to the feeling that God should be a perfect man, that God should include in his nature the feminine element. The progressive exaltation of the Virgin Mary, the work of Catholic piety, having its beginning in the expression Mother of God, ...has culminated in attributing to her the status of co-redeemer and in the dogmatic declaration of her conception without the stain of original sin. Hence she now occupies a position between Humanity and Divinity and nearer Divinity than Humanity. And it has been surmised that in course of time she may perhaps even come to be regarded as yet another personal manifestation of the Godhead.

The term many presupposes the term one, and the term one presupposes the term many.

A third illusion haunts us, that a long duration, as a year, a decade, a century, is valuable. But an old French sentence says, "God works in moments," - "En peu d'heure Dieu labeure." We ask for long life, but 't is deep life, or grand moments, that signify. Let the measure of time be spiritual, not mechanical. Life is unnecessarily long. Moments of insight, of fine personal relation, a smile, a glance, - what ample borrowers of eternity they are! Life culminates and concentrates; and Homer said, "The Gods ever give to mortals their appointed share of reason only on one day."

Speciesism is an attitude of prejudice towards beings because they're not members of our species, so just as racism means that you're prejudiced against beings who are not members of your race and sexism means you're prejudiced against people of the other sex. So we humans tend to be speciesist in we think that any being that is a member of the species homo sapien just automatically has a higher moral status and is more important than any being that is a member of any other species, irrespective of the actual characteristics of those beings.

Because we cannot discover God's throne in the sky with a radiotelescope or establish (for certain) that a beloved father or mother is still about in a more or less corporeal form, people assume that such ideas are "not true." I would rather say that they are not "true" enough, for these are conceptions of a kind that have accompanied human life from prehistoric times, and that still break through into consciousness at any provocation.

What is called an acute knowledge of human nature is mostly nothing but the observer's own weaknesses reflected back from others.
