Baruch Spinoza: Doing

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
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.

Letter 21 (73) to Henry Oldenburg, November (1675)
Variant translation: The eternal wisdom of God … has shown itself forth in all things, but chiefly in the mind of man, and most of all in Jesus Christ.
Context: I do not think it necessary for salvation to know Christ according to the flesh : but with regard to the Eternal Son of God, that is the Eternal Wisdom of God, which has manifested itself in all things and especially in the human mind, and above all in Christ Jesus, the case is far otherwise. For without this no one can come to a state of blessedness, inasmuch as it alone teaches, what is true or false, good or evil. And, inasmuch as this wisdom was made especially manifest through Jesus Christ, as I have said, his disciples preached it, in so far as it was revealed to them through him, and thus showed that they could rejoice in that spirit of Christ more than the rest of mankind. The doctrines added by certain churches, such as that God took upon himself human nature, I have expressly said that I do not understand; in fact, to speak the truth, they seem to me no less absurd than would a statement, that a circle had taken upon itself the nature of a square. This I think will be sufficient explanation of my opinions concerning the three points mentioned. Whether it will be satisfactory to Christians you will know better than I.

Context: With the judgment of the angels and the sentence of the saints, we anathematize, execrate, curse and cast out Baruch de Espinoza, the whole of the sacred community assenting, in presence of the sacred books with the six-hundred-and-thirteen precepts written therein, pronouncing against him the malediction wherewith Elisha cursed the children, and all the maledictions written in the Book of the Law. Let him be accursed by day, and accursed by night; let him be accursed in his lying down, and accursed in his rising up; accursed in going out and accursed in coming in. May the Lord never more pardon or acknowledge him; may the wrath and displeasure of the Lord burn henceforth against this man, load him with all the curses written in the Book of the Law, and blot out his name from under the sky; may the Lord sever him from all the tribes of Israel, weight him with all the maledictions of the firmament contained in the Book of Law; and may all ye who are obedient to the Lord your God be saved this day.
Hereby then are all admonished that none hold converse with him by word of mouth, none hold communication with him by writing; that no one do him any service, no one abide under the same roof with him, no one approach within four cubits' length of him, and no one read any document dictated by him, or written by his hand.

Context: This impels me, before going into your reasons, to set forth briefly my opinion on the question, whether the world was made by chance. But I answer, that as it is clear that chance and necessity are two contraries, so is it also clear, that he, who asserts the world to be a necessary effect of the divine nature, must utterly deny that the world has been made by chance; whereas, he who affirms that God need not have made the world, confirms, though in different language, the doctrine that it has been made by chance; inasmuch as he maintains that it proceeds from a wish, which might never have been formed. However, as this opinion and theory is on the face of it absurd, it is commonly very unanimously admitted, that God's will is eternal, and has never been indifferent; hence... the world is a necessary effect of the divine nature. Let them call it will, understanding, or any name they like, they come at last to the same conclusion, that under different names they are expressing one and the same thing. If you ask them, whether the divine will does not differ from the human, they answer, that the former has nothing in common with the latter except its name; especially as they generally admit that God's will, understanding, intellect, essence, and nature are all identical; so I... lest I... confound the divine nature with the human, do not assign to God human attributes, such as will, understanding, attention, hearing, &c. I therefore say, as I have said already, that the world is a necessary effect of the divine nature, and that it has not been made by chance. I think this is enough to persuade you, that the opinion of those (if such there be) who say that the world has been made by chance, is entirely contrary to mine; and relying on this hypothesis, I proceed to examine those reasons which lead you to infer the existence of all kinds of ghosts.<!--pp. 381-382

Context: In the state of nature, wrong-doing is impossible; or, if anyone does wrong, it is to himself, not to another. For no one by the law of nature is bound to please another, unless he chooses, nor to hold anything to be good or evil, but what he himself, according to his own temperament, pronounces to be so; and, to speak generally, nothing is forbidden by the law of nature, except what is beyond everyone's power.<!-- 23

Context: Beauty, my dear Sir, is not so much a quality of the object beheld, as an effect in him who beholds it. If our sight were longer or shorter, or if our constitution were different, what now appears beautiful to us would seem misshapen, and what we now think misshapen we should regard as beautiful. The most beautiful hand seen through the microscope will appear horrible. Some things are beautiful at a distance, but ugly near; thus things regarded in themselves, and in relation to God, are neither ugly nor beautiful. Therefore, he who says that God has created the world, so that it might be beautiful, is bound to adopt one of the two alternatives, either that God created the world for the sake of men's pleasure and eyesight, or else that He created men's pleasure and eyesight for the sake of the world. Now, whether we adopt the former or the latter of these views, how God could have furthered His object by the creation of ghosts, I cannot see. Perfection and imperfection are names which do not differ much from the names beauty and ugliness.<!--p. 382

Letter 74 (76) to Albert Burgh (1675) http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php%3Ftitle=1711&chapter=144250&layout=html&Itemid=27
Context: You seem to wish to employ reason, and ask me, "How I know that my philosophy is the best among all that have ever been taught in the world, or are being taught, or ever will be taught?" a question which I might with much greater right ask you; for I do not presume that I have found the best philosophy, I know that I understand the true philosophy. If you ask in what way I know it, I answer: In the same way as you know that the three angles of a triangle are equal to two right angles: that this is sufficient, will be denied by no one whose brain is sound, and who does not go dreaming of evil spirits inspiring us with false ideas like the true. For the truth is the index of itself and of what is false.
But you, who presume that you have at last found the best religion, or rather the best men, on whom you have pinned your credulity, you, "who know that they are the best among all who have taught, do now teach, or shall in future teach other religions. Have you examined all religions, ancient as well as modern, taught here and in India and everywhere throughout the world? And, if you, have duly examined them, how do you know that you have chosen the best" since you can give no reason for the faith that is in you? But you will say, that you acquiesce in the inward testimony of the Spirit of God, while the rest of mankind are ensnared and deceived by the prince of evil spirits. But all those outside the pale of the Romish Church can with equal right proclaim of their own creed what you proclaim of yours.
As to what you add of the common consent of myriads of men and the uninterrupted ecclesiastical succession, this is the very catch-word of the Pharisees. They with no less confidence than the devotees of Rome bring forward their myriad witnesses, who as pertinaciously as the Roman witnesses repeat what they have heard, as though it were their personal experience. Further, they carry back their line to Adam. They boast with equal arrogance, that their Church has continued to this day unmoved and unimpaired in spite of the hatred of Christians and heathen. They more than any other sect are supported by antiquity. They exclaim with one voice, that they have received their traditions from God himself, and that they alone preserve the word of God, both written and unwritten. That all heresies have issued from them, and that they have remained constant through thousands of years under no constraint of temporal dominion, but by the sole efficacy of their superstition, no one can deny. The miracles they tell of would tire a thousand tongues. But their chief boast is that they count a far greater number of martyrs than any other nation, a number which is daily increased by those who suffer with singular constancy for the faith they profess; nor is their boasting false. I myself knew among others of a certain Judah called the faithful, who in the midst of the flames, when he was already thought to be dead, lifted his voice to sing the hymn beginning, "To thee, o God, I offer up my soul", and so singing perished.

Albert Einstein, in response to the telegrammed question of New York's Rabbi Herbert S. Goldstein in (24 April 1929) ; he later expanded on his comments about Spinoza's and his own ideas on religion elsewhere : "I can understand your aversion to the use of the term "religion" to describe an emotional and psychological attitude which shows itself most clearly in Spinoza … I have not found a better expression than "religious" for the trust in the rational nature of reality that is, at least to a certain extent, accessible to human reason." — as quoted in Einstein : Science and Religion by Arnold V.
