Joseph Priestley Quotes

It may, perhaps, be true, though we cannot distinctly see it to be so, that as all finite things require a cause, infinites admit of none. It is evident, that nothing can begin to be without a cause; but it by no means follows from thence, that that must have had a cause which had no beginning. But whatever there may be in this conjecture, we are constrained, in pursuing the train of causes and effects, to stop at last at something uncaused. That any being should be self created is evidently absurd, because that would suppose that he had a being before he had, or that he existed, and did not exist at the same time. For want of clearer knowledge of this subject, we are obliged to content ourselves with terms that convey only negative ideas, and to say that God is a being untreated or uncaused; and this is all that we mean when we sometimes say that he is self existent.

It is hardly possible not to suspect the truth of this doctrine of atonement, when we consider that the general maxims to which it may be reduced, are nowhere laid down, or asserted, in the Scriptures, but others quite contrary to them.

As I conceive this doctrine to be a gross misrepresentation of the character and moral government of God, and to affect many other articles in the scheme of Christianity, greatly disfiguring and depraving it; I shall show, in a fuller manner than I mean to do with respect to any other corruption of Christianity, that it has no countenance whatever in reason, or the Scriptures; and, therefore, that the whole doctrine of atonement, with every modification of it, has been a departure from the primitive and genuine doctrine of Christianity.

The History of Electricity is a field full of pleasing objects, according to all the genuine and universal principles of taste, deduced from a knowledge of human nature. Scenes like these, in which we see a gradual rise and progress in things, always exhibit a pleasing spectacle to the human mind. Nature, in all her delightful walks, abounds with such views, and they are in a more especial manner connected with every thing that relates to human life and happiness; things, in their own nature, the most interesting to us. Hence it is, that the power of association has annexed crowds of pleasing sensations to the contemplation of every object, in which this property is apparent. This pleasure, likewise, bears a considerable resemblance to that of the sublime, which is one of the most exquisite of all those that affect the human imagination. For an object in which we see a perpetual progress and improvement is, as it were, continually rising in its magnitude; and moreover, when we see an actual increase, in a long period of time past, we cannot help forming an idea of an unlimited increase in futurity; which is a prospect really boundless, and sublime.

Indeed, if any man can say, that it is not an interesting question, whether his existence terminate at death, or is to be resumed at a future period, and then to continue for ever, he must be of a low and abject mind. To a rational being, capable of contemplating the wonders of nature, and of investigating the laws of it, and to a being of a social disposition, his existence, and the continuance of his rational faculties, must be an object of unspeakable value to him; and consequently he must ardently wish that christianity... may be true. For to a philosopher, who forms his judgment by what he actually observes, the doctrine of soul, capable of subsisting and acting when the body is in the grave, will never give any satisfaction. To every person, therefore, who is capable of enjoying his existence, the christian doctrine of a resurrection opens a glorious and transporting prospect.

Our anxiety during the King of France's escape, and our joy on his capture, cannot be described. I hope the new constitution is now effectually established, and that all attempts to overturn it will be in vain. The high-party here are mortified in the extreme. They would have had France involved in a most ruinous civil war, for the imaginary rights of one man. A majority, I fear, of Englishmen are in these sentiments, so that we are far indeed behind the French. In spite of all we can write or do, an attachment to high maxims of government gains ground here, and the love of liberty is on the decline. Such is the influence of the court. Nothing but public difficulties will open our eyes.

I am sorry... to have occasion to admonish Mr. Gibbon, that he should have distinguished better than he has done between christianity itself, and the corruptions of it. ...He should not have taken it for granted, that the doctrine of three persons in one God, or the doctrine of atonement for the sins of all mankind, by the death of one man, were any parts of the christian system; when, if he had read the New Testament for himself, he must have seen the doctrine of the proper unity of God, and also that of his free mercy to the penitent, in almost every page of it.

We find upon all occasions, the early Christian writers speak of the Father as superior to the Son, and in general they give him the title of God, as distinguished from the Son; and sometimes they expressly call him, exclusively of the Son, the only true God; a phraseology which does not at all accord with the idea of the perfect equality of all the persons in the Trinity. But it might well be expected, that the advances to the present doctrine of the Trinity should be gradual and slow. It was, indeed, some centuries before it was completely formed.

Were it possible to trace the succession of ideas in the mind of Sir Isaac Newton, during the time that he made his greatest discoveries, I make no doubt but our amazement at the extent of his genius would a little subside. But if, when a man publishes discoveries, he, either through design, or through habit, omit the intermediate steps by which he himself arrived at them; it is no wonder that his speculations confound others... [W]here we see him most in the character of an experimental philosopher, as in his optical inquiries... we may easily conceive that many persons, of equal patience and industry... might have done what he did. And were it possible to see in what manner he was first led to those speculations, the very steps by which he pursued them, the time that he spent in making experiments, and all the unsuccessful and insignificant ones that he made in the course of them; as our pleasure of one kind would be increased, our admiration would probably decrease. Indeed he himself used candidly to acknowledge, that if he had done more than other men, it was owing rather to a habit of patient thinking, than to any thing else. ...[T]he interests of science have suffered by the excessive admiration and wonder, with which several first rate philosophers are considered; and... an opinion of the greater equality of mankind, in point of genius, and powers of understanding, would be of real service in the present age.

The unity of God is a doctrine on which the greatest stress is laid in the whole system of revelation. To guard this most important article was the principal object of the Jewish religion; and, notwithstanding the proneness of the Jews to idolatry, at length it fully answered its purpose in reclaiming them, and in impressing the minds of many persons of other nations in favour of the same fundamental truth. The Jews were taught by their prophets to expect a Messiah, who was to be descended from the tribe of Judah, and the family of David, — a person in whom themselves and all the nations of the earth should be blessed; but none of their prophets gave them an idea of any other than a man like themselves in that illustrious character, and no other did they ever expect, or do they expect to this day. Jesus Christ, whose history answers to the description given of the Messiah by the prophets, made no other pretensions; referring all his extraordinary power to God, his Father, who, he expressly says, spake and acted by him, and who raised him from the dead: and it is most evident that the apostles, and all those who conversed with our Lord before and after his resurrection, considered him in no other light than simply as "a man approved of God, by wonders and signs which God did by him."

As the greatest things often take their rise from the smallest beginnings, so the worst things sometimes proceed from good intentions. This was certainly the case with respect to the origin of Christian Idolatry. All the early heresies arose from men who wished well to the gospel, and who meant to recommend it to the Heathens, and especially to philosophers among them, whose prejudices they found great difficulty in conquering. Now we learn from the writings of the apostles themselves, as well as from the testimony of later writers, that the circumstance at which mankind in general, and especially the more philosophical part of them, stumbled the most, was the doctrine of a crucified Saviour. They could not submit to become the disciples of a man who had been exposed upon a cross, like the vilest malefactor. Of this objection to Christianity we find traces in all the early writers, who wrote in defence of the gospel against the unbelievers of their age, to the time of Lactantius; and probably it may be found much later. He says, "I know that many fly from the truth out of their abhorrence of the cross." We, who only learn from history that crucifixion was a kind of death to which slaves and the vilest of malefactors were exposed, can but very imperfectly enter into their prejudices, so as to feel what they must have done with respect to it. … Though this circumstance was "unto the Jews a stumbling-block, and unto the Greeks foolishness," it was to others "the power of God and the wisdom of God." 1 Cor. i. 23, 24. For this circumstance at which they cavilled, was that in which the wisdom of God was most conspicuous; the death and resurrection of a man, in all respects like themselves, being better calculated to give other men an assurance of their own resurrection, than that of any super-angelic being, the laws of whose nature they might think to be very different from those of their own. But, "since by man came death, so by man came also the resurrection of the dead." Later Christians, however, and especially those who were themselves attached to the principles of either the Oriental or the Greek philosophy, unhappily took another method of removing this obstacle; and instead of explaining the wisdom of the divine dispensations in the appointment of a man, a person in all respects like unto his brethren, for the redemption of men, and of his dying in the most public and indisputable manner, as a foundation for the clearest proof of a real resurrection, and also of a painful and ignominious death, as an example to his followers who might be exposed to the same … they began to raise the dignity of the person of Christ, that it might appear less disgraceful to be ranked amongst his disciples.

In his Opus Majus he demonstrates, that if a transparent body, interposed between the eye and an object, be convex towards the eye, the object will appear magnified. This observation our author certainly had from Alhazen... this writer [Bacon] gives us figures, representing the progress of rays of light through his spherical segment, as well as endeavours to give reasons why objects are magnified... From the writings of Alhazen and these observations and experiments of Bacon together, it is not improbable that some monks gradually hit upon the construction of spectacles, to which Bacon's lesser segment, not withstanding his mistake concerning it, was a nearer approach than Alhazen's... Whoever they were that pursued the discoveries of Bacon, they probably observed, that a very small convex glass, when held at a greater distance from a book, would magnify the letters more than when it was placed close to them, in which position only Bacon seemed to have used it. In the next place, they might try whether two of these small segments of a sphere placed together, or a glass convex on both sides, would not magnify more than one of them. They would then find, that two of these glasses, one for each eye, would answer the purpose of reading better than one; and lastly they might find, that different degrees of convexity, suited different persons. It is certain that spectacles were well known in the 13th century, and not long before. ...It would certainly have been a great satisfaction to us to have been able to trace the actual steps in the progress of this most useful invention, without which most persons who have a taste for reading must have had the melancholy prospect of passing a very dull and joyless old age; and must have been deprived of the pleasure of entertaining themselves by conversing with the absent and the dead, when they were no longer capable of acting their part among the living. Telescopes and microscopes are to be numbered among the superfluities of life when compared to spectacles, which may now be ranked almost among the necessities of it; since the arts of reading and writing are almost universal.

Great as Bacon was, he was far from being free from the mistakes and prejudices of those who went before him. Even some of the most wild and absurd opinions of the antients have the sanction of his approbation and authority. He does not hesitate to assent to an opinion... that visual rays proceed from the eye; giving this reason for it, that every thing in nature is qualified to discharge its proper functions by its own powers, in the same manner as the sun, and other celestial bodies. He acknowledges, however, that the presence of light, as well as several other circumstances, is necessary to vision.

To different minds, the same world is a hell, and a heaven.

The mind of man will never be able to contemplate the being, perfections, and providence of God without meeting with inexplicable difficulties. We may find sufficient reason for acquiescing in the darkness which involves these great subjects, but we must never expect to see them set in a perfectly clear light. But notwithstanding this, we may know enough of the divine being, and of his moral government, to make us much better and happier beings than we could be without such knowledge; and even the consideration of the insuperable difficulties referred to above is not without its use, as it tends to impress the mind with sentiments of reverence, humility, and submission.
