Frederick Douglass · 1881

Douglass describes shifting from odd jobs in New Bedford to steady work at Mr. Richmond’s brass foundry, where he reads newspapers while operating bellows and avoids abuse from hostile coworkers.

of work that came to hand. I sawed wood, shoveled coal, dug cellars, moved rubbish from back yards, worked on the wharves, loaded and unloaded vessels, and scoured their cabins. I afterward got steady work at the brass-foundry owned by Mr. Richmond. My duty here was to blow the bellows, swing the crane, and empty the flasks in which castings were made; and at times this was hot and heavy work. The articles produced …

The Koran (Al-Qur'an) secondary

G. Margoliouth (George) · 610-632 CE (revelations compiled progressively; book published after the prophet’s death)
Book carefully concocted from various sources, and with much extraneous aid, and published as a divine oracle, then it would seem that the author is at once open to the charge of the grossest imposture, and even of impious blasphemy. The evidence rather shews, that in all he did and wrote, Muhammad was actuated by a sincere desire to deliver his countrymen from the grossness of its debasing idolatries-that he was urged on by an intense desire to proclaim that great truth of the Unity of the Godhead which had taken full possession of his own soul-that the end to be attained justified to his mind the means he adopted in the production of his Suras-that he worked himself up into a belief that he had received a divine call-and that he was carried on by the force of circumstances, and by gradually increasing successes, to believe himself the accredited messenger of Heaven. The earnestness of those convictions which at Mecca sustained him under persecution, and which perhaps led him, at any price as it were, and by any means, not even excluding deceit and falsehood, to endeavour to rescue his countrymen from idolatry,-naturally stiffened at Medina into tyranny and unscrupulous violence. At the same time, he was probably, more or less, throughout his whole career, the victim of a certain amount of self-deception. A cataleptic13 subject from his early youth, born-according to the traditions-of a highly nervous and excitable mother, he would be peculiarly liable to morbid and fantastic hallucinations, and alternations of excitement and depression, which would win for him, in the eyes of his ignorant countrymen, the credit of being inspired. It would be easy for him to persuade himself that he was "the seal of the Prophets," (1/11)

Margoliouth weighs Muhammad’s sincerity, suggesting Muhammad was neither simple impostor nor merely rational author, but driven by faith, self-deception, persecution at Mecca, and escalating violence at Medina.

the proclaimer of a doctrine of the Divine Unity, held and taught by the Patriarchs, especially by Abraham-a doctrine that should present to mankind Judaism divested of its Mosaic ceremonial, and Christianity divested of the Atonement and the Trinity14-doctrine, as he might have believed, fitted and destined to absorb Judaism, Christianity, and Idolatry; and this persuasion, once admitted into his mind as a convictio…

This passage continues the same interpretive thesis about Muhammad’s sincerity, faith, persecution, self-deception, and belief in receiving a divine call, repeating earlier argumentation rather than adding new claims.

It would be easy for him to persuade himself that he was "the seal of the Prophets," (6/11)

The author argues Muhammad sincerely sought to end Mecca’s idolatries and teach God’s unity, while also being influenced by self-deception and possible hallucinations, contrasting Mecca persecution with Medina tyranny, and discussing early adoption of Islam by enslaved Christians.

The translator argues Muhammad’s Qur’an-building reflects sincerity mixed with self-deception, then presents Meccan oaths and resurrection judgments, including warnings to the unbelievers and stories such as Thamud’s rejected message and punishments.

BY the heaven, and by the NIGHT-COMER! But who shall teach thee what the night-comer is? 'Tis the star of piercing radiance. Over every soul is set a guardian. Let man then reflect out of what he was created.

The translator/annotator argues that Muhammad sought to end idolatry and teach God’s unity, but also claims persecution at Mecca and later success fostered self-deception and escalating violence, then appends Qur’an Sura 51’s warnings and end-times judgment.

We had surely seized him by the right hand, And had cut through the vein of his neck.5 Nor would We have withheld any one of you from him. But, verily, It (the Koran) is a warning for the God-fearing; And we well know that there are of you who treat it as a falsehood.

It reiterates that the spelling ‘Peyps’ and ‘Peaps’ likely represented the sound ‘Pepes,’ and contrasts editor research with the Diary’s more vivid presentation of Pepys’s true character.

pronunciation of the name was fixed, but there is every reason to suppose that the spellings of Peyps and Peaps were intended to represent the sound Pepes rather than Peeps. In spite of all the research which has brought to light so many incidents of interest in the life of Samuel Pepys, we cannot but feel how dry these facts are when placed by the side of the living details of the Diary.

So spake he, and the mighty prince Telemachus smiled, and glanced at his father, while he shunned the eye of the swineherd. Now when they had ceased from the work and got supper ready, they fell to feasting, and their hearts lacked not ought of the equal banquet. But when they had put from them the desire of meat and drink, they bethought them of rest, and took the boon of sleep.

He says descent with modification likely covers whole biological classes, argues animals probably share only a few progenitors, and uses analogy plus shared biological features to infer a single primordial origin.

from those who believe in the mutability of species, on their own side they ignore the whole subject of the first appearance of species in what they consider reverent silence. It may be asked how far I extend the doctrine of the modification of species. The question is difficult to answer, because the more distinct the forms are which we may consider, by so much the arguments fall away in force. But some arguments o…

Narrative of the Life of Frederick Douglass, an American Slave primary

Frederick Douglass · 1845

Phillips highlights Douglass’s Chesapeake Bay reflections as the narrative’s most moving passage, denounces slavery as entombing the mind and reducing people to beasts, and attacks skepticism that excuses slavery’s atrocities.

perils he encountered in his endeavors to escape from his horrible doom! and how signal have been his deliverance and preservation in the midst of a nation of pitiless enemies! This Narrative contains many affecting incidents, many passages of great eloquence and power; but I think the most thrilling one of them all is the description *Douglass* gives of his feelings, as he stood soliloquizing respecting his fate, a…

Aeneas admires the divinely wrought shield’s scenes even without knowing their names, taking up the fame and fortune it promises for his line and future race.

Sura 23 (The Believers) outlines who the ‘happy believers’ are—humility in prayer, charity, restraint of desire within lawful bounds, and faithfulness to trusts and covenants—then describes human creation stages, resurrection, rain and cultivation signs, and introduces Noah’s preaching to serve God alone.

The Interesting Narrative of the Life of Olaudah Equiano, Or Gustavus Vassa, The African primary

Olaudah Equiano (also known as Gustavus Vassa) · 1789 (written/compiled for publication; edition-letter dated March 24, 1789)
CHAPTER I. (18/110)

Equiano recounts enslaved people’s beliefs about magic that moves ships, the arrival of another vessel and handshakes between crews, then describes overcrowded conditions causing suffocation, disease, death, chains, and filth.

I asked how the vessel could go? they told me they could not tell; but that there were cloths put upon the masts by the help of the ropes I saw, and then the vessel went on; and the white men had some spell or magic they put in the water when they liked in order to stop the vessel.

CHAPTER I. (20/110)

Equiano explains fearful misunderstandings of Europeans’ talk about eating him, loses a man overboard, interprets fish and calm as magical or divine signs, and then learns the fish would swallow bodies.

He used often to tell him jocularly that he would kill me to eat. Sometimes he would say to me--the black people were not good to eat, and would ask me if we did not eat people in my country. I said, No: then he said he would kill Dick (as he always called him) first, and afterwards me. Though this hearing relieved my mind a little as to myself, I was alarmed for Dick and whenever he was called I used to be very much…

DEMETRIUS Ingenious men have long observed a resemblance between the arts and the bodily senses. And they were first led to do so, I think, by noticing the way in which, both in the arts and with our senses, we examine opposites. Judgment once obtained, the use to which we put it differs in the two cases. Our senses are not meant to pick out black rather than white, to prefer sweet to bitter, or soft and yielding…

§ 2. Metaphysical Exposition of this Conception. By means of the external sense (a property of the mind), we represent to ourselves objects as without us, and these all in space. Herein alone are their shape, dimensions, and relations to each other determined or determinable.

Both are transcendental, not merely because they themselves precede à priori all experience, but also because they form the basis for the possibility of other cognition à priori.

Kant states the first analogy—substance’s permanence—arguing that in all changes substance remains constant in quantity, since time is the form of internal intuition and permanence underlies determinations of succession and simultaneity.

Principle of the Permanence of Substance. In all changes of phenomena, substance is permanent, and the quantum thereof in nature is neither increased nor diminished. PROOF. All phenomena exist in time, wherein alone as substratum, that is, as the permanent form of the internal intuition, coexistence and succession can be represented.

[31] Persius, Satirae, iii.83-84. The determinations of a substance, which are only particular modes of its existence, are called accidents. They are always real, because they concern the existence of substance (negations are only determinations, which express the non-existence of something in the substance).

Kant resolves an apparent problem by saying cause and effect may be simultaneous; we must track the order of time relations even if the time gap vanishes, and he links causality to action, force, and substance.

principle of the relation of causality in the succession of phenomena is therefore valid for all objects of experience, because it is itself the ground of the possibility of experience.

Kant argues that all change obeys continuity: no smallest degree of reality or time exists, so a new state arises through continuous causal activity (momentum), grounded in how time is internally synthesized.

which, in so far as it is uniform, we call a momentum. The change does not consist of these momenta, but is generated or produced by them as their effect. Such is the law of the continuity of all change, the ground of which is that neither time itself nor any phenomenon in time consists of parts which are the smallest possible, but that, notwithstanding, the state of a thing passes in the process of a change through…

PROOF. Things are coexistent, when in empirical intuition the perception of the one can follow upon the perception of the other, and vice versa—which cannot occur in the succession of phenomena, as we have shown in the explanation of the second principle.

[33] German The following remarks may be useful in the way of explanation. In the mind, all phenomena, as contents of a possible experience, must exist in community (communio) of apperception or consciousness, and in so far as it is requisite that objects be represented as coexistent and connected, in so far must they reciprocally determine the position in time of each other and thereby constitute a whole.

In the remark, Kant says idealism wrongly assumes internal experience is the only immediate basis, but external experience must be immediate for internal determination of time, since imagining an external sense already presupposes it.

PROOF I am conscious of my own existence as determined in time. All determination in regard to time presupposes the existence of something permanent in perception. But this permanent something cannot be something in me, for the very reason that my existence in time is itself determined by this permanent something. It follows that the perception of this permanent existence is possible only through a thing without me …
