Baruch Spinoza Quotes

Baruch Spinoza was a Dutch philosopher of Sephardi/Portuguese origin. By laying the groundwork for the 18th-century Enlightenment and modern biblical criticism, including modern conceptions of the self and the universe, he came to be considered one of the great rationalists of 17th-century philosophy. Along with René Descartes, Spinoza was a leading philosophical figure of the Dutch Golden Age. Spinoza's given name, which means "Blessed", varies among different languages. In Hebrew, it is written ברוך שפינוזה. His Portuguese name is Benedito "Bento" de Espinosa. In his Latin works, he used Latin: Benedictus de Spinoza.

Spinoza's magnum opus, Ethics, was published posthumously in 1677. The work opposed Descartes' philosophy on mind–body dualism, and earned Spinoza recognition as one of Western philosophy's most important thinkers. In the Ethics, "Spinoza wrote the last indisputable Latin masterpiece, and one in which the refined conceptions of medieval philosophy are finally turned against themselves and destroyed entirely". Georg Wilhelm Friedrich Hegel said, "You are either a Spinozist or not a philosopher at all." His philosophical accomplishments and moral character prompted philosopher Gilles Deleuze to name him "the 'prince' of philosophers."

Spinoza was raised in a Portuguese Jewish community in Amsterdam. He developed highly-controversial ideas regarding the authenticity of the Hebrew Bible and the nature of the Divine. Jewish religious authorities issued a herem against him, causing him to be effectively shunned by Jewish society at age 23. His books were also later put on the Catholic Church's Index of Forbidden Books.

Spinoza lived an outwardly-simple life as a lens grinder, turning down rewards and honours throughout his life, including prestigious teaching positions. He died at the age of 44 allegedly of a lung illness, perhaps tuberculosis or silicosis exacerbated by the inhalation of fine glass dust while grinding optical lenses. He is buried in the churchyard of the Christian Nieuwe Kerk in The Hague.

Baruch Spinoza Quotes

“In practical life we are compelled to follow what is most probable ; in speculative thought we are compelled to follow truth.”

Letter 56 (60), to Hugo Boxel (1674) http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php%3Ftitle=1711&chapter=144218&layout=html&Itemid=27
Source: The Letters
Context: When you say that if I deny, that the operations of seeing, hearing, attending, wishing, &c., can be ascribed to God, or that they exist in him in any eminent fashion, you do not know what sort of God mine is; I suspect that you believe there is no greater perfection than such as can be explained by the aforesaid attributes. I am not astonished; for I believe that, if a triangle could speak, it would say, in like manner, that God is eminently triangular, while a circle would say that the divine nature is eminently circular. Thus each would ascribe to God its own attributes, would assume itself to be like God, and look on everything else as ill-shaped.
The briefness of a letter and want of time do not allow me to enter into my opinion on the divine nature, or the questions you have propounded. Besides, suggesting difficulties is not the same as producing reasons. That we do many things in the world from conjecture is true, but that our redactions are based on conjecture is false. In practical life we are compelled to follow what is most probable; in speculative thought we are compelled to follow truth. A man would perish of hunger and thirst, if he refused to eat or drink, till he had obtained positive proof that food and drink would be good for him. But in philosophic reflection this is not so. On the contrary, we must take care not to admit as true anything, which is only probable. For when one falsity has been let in, infinite others follow.
Again, we cannot infer that because sciences of things divine and human are full of controversies and quarrels, therefore their whole subject-matter is uncertain; for there have been many persons so enamoured of contradiction, as to turn into ridicule geometrical axioms.

“We feel and experience ourselves to be eternal.”

“But love for an object eternal and infinite feeds the mind with joy alone, and a joy which is free from all sorrow. This is something greatly to be desired and to be sought with all our strength.”
Sed amor erga rem aeternam et infinitam sola laetitia pascit animum, ipsaque omnis tristitiae est expers; quod valde est desiderandum totisque viribus quaerendum.

On the Improvement of the Understanding (1662)

“In 1663 Spinoza published the only work to which he ever set his name… He had prepared a summary of the second part of Descartes' 'Principles of Philosophy' for the use of a pupil… Certain of Spinoza's friends became curious about this manual and desired him to treat the first part of Descartes' work also in the same manner. This was done within a fortnight and Spinoza was then urged to publish the book, which he readily agreed to do upon condition that one of his friends would revise the language and write a preface explaining that the author did not agree with all the Cartesian doctrine… The contents… [included] an appendix of 'Metaphysical Reflections,' professedly written from a Cartesian point of view, but often giving significant hints of the author's real divergence from Descartes….'On this opportunity,' he writes to Oldenburg, 'we may find some persons holding the highest places in my country… who will be anxious to see those other writings which I acknowledge for my own, and will therefore take such order that I can give them to the world without danger of any inconvenience. If it so happens, I doubt not that I shall soon publish something; if not, I will rather hold my peace than thrust my opinions upon men against the will of my country and make enemies of them.'… The book on Descartes excited considerable attention and interest, but the untoward course of public events in succeeding years was unfavourable to a liberal policy, and deprived Spinoza of the support for which he had looked….
If Spinoza had ever been a disciple of Descartes, he had completely ceased to be so… He did not suppose the geometrical form of statement and argument to be an infallible method of arriving at philosophical truth; for in this work he made use of it to set forth opinions with which he himself did not agree, and proofs with which he was not satisfied. We do not know to what extent Spinoza's manual was accepted or taken into use by Cartesians, but its accuracy as an exposition of Descartes is beyond question. One of the many perverse criticisms made on Spinoza by modern writers is that he did not understand the fundamental proposition cogito ergo sum. In fact he gives precisely the same explanation of it that is given by Descartes himself in the Meditations.”

“Needs must it be hard, since it is so seldom found. How would it be possible, if salvation were ready to our hand, and could without great labour be found, that it should be by almost all men neglected? But all things excellent are as difficult as they are rare.”
Et sane arduum debet esse, quod adeo raro reperitur. Qui enim posset fieri, si salus in promptu esset et sine magno labore reperiri posset, ut ab omnibus fere negligeretur? Sed omnia praeclara tam difficilia, quam rara sunt.

“This endeavour to do a thing or leave it undone, solely in order to please men, we call ambition, especially when we so eagerly endeavour to please the vulgar, that we do or omit certain things to our own or another's hurt : in other cases it is generally called kindliness.”
Hic conatus aliquid agendi et etiam omittendi ea sola de causa ut hominibus placeamus, vocatur ambitio præsertim quando adeo impense vulgo placere conamur ut cum nostro aut alterius damno quædam agamus vel omittamus; alias humanitas appellari solet.

“Human infirmity in moderating and checking the emotions I name bondage: for, when a man is a prey to his emotions, he is not his own master, but lies at the mercy of fortune: so much so, that he is often compelled, while seeing that which is better for him, to follow that which is worse.”
Humanam impotentiam in moderandis et coercendis affectibus servitutem voco; homo enim affectibus obnoxius sui juris non est sed fortunæ in cujus potestate ita est ut sæpe coactus sit quanquam meliora sibi videat, deteriora tamen sequi.

“How much do I love that noble man
More than I could tell with words
I fear though he'll remain alone
With a holy halo of his own.”

Wie lieb ich diesen edlen Mann
Mehr als ich mit Worten sagen kann.
Doch fürcht' ich, dass er bleibt allein
Mit seinem strahlenen Heiligenschein.

“Of a commonwealth, whose subjects are but hindered by terror from taking arms, it should rather be said, that it is free from war, than that it has peace. For peace is not mere absence of war, but is a virtue that springs from force of character : for obedience is the constant will to execute what, by the general decree of the commonwealth, ought to be done. Besides, that commonwealth, whose peace depends on the sluggishness of its subjects, that are led about like sheep, to learn but slavery, may more properly be called a desert than a commonwealth.”
Civitas, cuius subditi metu territi arma non capiunt, potius dicenda est, quod sine bello sit, quam quod pacem habeat. Pax enim non belli privatio, sed virtus est, quae ex animi fortitudine oritur; est namque obsequium constans voluntas id exsequendi, quod ex communi civitatis decreto fieri debet. Illa praeterea civitas, cuius pax a subditorum inertia pendet, qui scilicet veluti pecora ducuntur, ut tantum servire discant, rectius solitudo, quam civitas dici potest.

Liberally rendered in A Natural History of Peace (1996) by Thomas Gregor as:
"Peace is not an absence of war; it is a virtue, a state of mind, a disposition for benevolence, confidence, justice."

“I pass, at length, to the third and perfectly absolute dominion, which we call democracy.”

“All laws which can be broken without any injury to another, are counted but a laughing-stock, and are so far from bridling the desires and lusts of men, that on the contrary they stimulate them.”

Source: Political Treatise (1677), Ch. 10, Of Aristocracy, Conclusion

Variant translation : Laws which can be broken without any wrong to one's neighbor are but a laughing-stoke ; and, so far from such laws restraining the appetites and lusts of mankind, they rather heighten them.

Variant: All laws which can be violated without doing any one any injury are laughed at. Nay, so far are they from doing anything to control the desires and passions of men, that, on the contrary, they direct and incite men's thoughts the more toward those very objects, for we always strive toward what is forbidden and desire the things we are not allowed to have. And men of leisure are never deficient in the ingenuity needed to enable them to outwit laws framed to regulate things which cannot be entirely forbidden... He who tries to determine everything by law will foment crime rather than lessen it.

“"Spinoza did not seek to found a sect, and he founded none"; yet all philosophy after him is permeated with his thought.”

“The ordinary surroundings of life which are esteemed by men (as their actions testify) to be the highest good, may be classed under the three heads — Riches, Fame, and the Pleasures of Sense: with these three the mind is so absorbed that it has little power to reflect on any different good.”

I, 3
Variant translation: The things which … are esteemed as the greatest good of all … can be reduced to these three headings, to wit : Riches, Fame, and Pleasure. With these three the mind is so engrossed that it cannot scarcely think of any other good.
