Studienbuch O

Braunes Studienbuch
(NL-Herder XXVI.5)

The so-called Braunes Studienbuch (Brown Notebook) is a quarto volume (17.5 x 20 cm), 70 sheets, with a brown cover. It is paginated (apparently by Herder) as I-IV (with I as the title-page) and then 1-137 (the inside back cover is p. 137). The text is all in ink (dark brown or black, on one page red), with pencilled markings by a later user. On the title-page (p. I): “Beiträge / fürs / Gedächtniß. / 1761. / 1762ff.”[1] Below which is a quote: “Der Weise / Der minder liest, als denkt, ˚.und minder schreibt, als liest. / ˚von Creuz.”[2] On p. II is a quote from Horace. This notebook is a collection of thoughts, notes on books read, sketches of letters, as well as a few lecture notes. The text below comes from pp. 32-35 and concerns Baumgarten §§796-99 (Rational Psychology) and §§803-62 (Natural Theology).

Previous transcription: AA 28: 28: 886-922.


Other transcribed text from this notebook can be found at Varia (Mathematics) (notebook pages 9, 10, and 21) and Varia (XXVI.5) (notebook pages 25, 67, 73, 123).


Two entries are of particular interest:

(1) On p. 32 (below): “bey Kant. 1sten mal. d. 21 Aug”[3] followed by two pages of notes from Kant’s metaphysics lectures concerning Baumgarten, §§796-808 (rational psychology and natural theology).

(2) On p. 123 (at Varia): “den 21. Aug. bei Kant das Collegium angefangen.”[4]

The text on this first page (ms 32) is complicated by the presence of several long marginal notes (in the left-margin), and a number of insertion-signs throughout the main text that are not entirely unambiguous. Details are given in the textual notes.


[1] “Articles for memory. 1761. 1762ff.”

[2]The Sage. Who reads less then thinks, and writes less than reads. / von Creuz.” Friedrich Karl Kasimir Freiherr von Creuz (1724-1770) was a German poet and civil servant who served out his brief life as a Hofrat (eventually Reichshofrat) in Hessen-Homburg. He was primarily an autodidact, with only a Gymnasium education for formal training. Herder quotes from his poetry in the "Poetisches Fach" portion of the notebook (pp. 66-83).

[3] “With Kant the 1st time, Aug 21”.

[4] “the 21st of Aug, begun the class with Kant”.

Da wir ˚.von den [a] Geistern geredt haben, so gehen wir z.um höchsten Geiste, ˚der alle geschaffen, ˚.und ˚den [b] höchsten Verstand besizzt. ˚Den Begriff [c]

˚.von ihm machen wir uns blos ˚durch ˚einen Schluß von uns.erer Seele ˚.auf ˚den höchsten Grad ˚der Fähigkeiten. [d] ˚.Man muß aber 1) sehen, ˚daß ˚.man ˚nicht unsere Mängel ˚.einmische, ˚.wie ˚.man sehr

Explanatory Notes

[1] [21. Aug.] A similar entry is found on p. 123 of this notebook (see). This appears to have been Herder’s first visit to Kant’s classroom, and would have taken place soon after the summer break in August (Herder enrolled at the university August 10, 1762). The date, however, leaves us with a puzzle, since August 21 of that year fell on a Saturday, a highly unlikely day for Kant to have been holding classes, and especially unlikely for the first day of classes after a break. It appears that the university was still using the Gregorian calendar during the Russian occupation; but if for some reason Herder was using the Julian calendar, then August 10 would have fallen on a Wednesday – equally implausible. But then again, perhaps the notes were not from the first day after vacation, but simply from the first day for Herder.

[2] [Schalen hingeworfen] See the Holstein-Beck notes on physical geography (AA 26.1: 69):

“An allen Orten der Erde selbst auf den Spitzen hoher Berge findet man große Haufen von Seemuscheln und andere Merkmaale des ehemaligen Meeresgrundes.”

[3] [Poltergeister] See Refl. #3807 (AA 17: 299), quoted in a corresponding note to RP/NT 763-C2.

[4] [Prediger in Wetterau] This example also appears at RP/NT 763-C3.

[5] [Buckingham] George Villiers (1592-1628), 1st Duke of Buckingham, and favorite to James I of England, was stabbed to death on 23 August 1628 by the army officer John Felton. Kant is referring to a well-known ghost story, where the ghost of George Villiers’ father appeared at night to a servant, who was told to warn his son that he must ingratiate himself with the people or else he would be murdered. After three such visitations, the servant met with the Duke, also conveying to him information given to him by the ghost that no one but the Duke would know, and that would warrant the servant’s message. This was a month or so before his assassination. A likely source of this story for Kant is Glanville (1701, 145-48). Felton is mentioned at EP 531-A3.

[6] [D. Faust] See the discussion of Faust at RP/NT 763-C3 and in the accompanying note.

[7] [haben die Geister auch Körper?] Baumgarten, §797, claims that each finite spirit has body.

[8] [Brustredner] This may be the same as, or else a miswrite or mishearing of, Bauchredner, a term used at RP/NT 763-C2 (see the corresponding note) and in Refl. #3807.

[9] [D. Semler] See the discussion of Semler in RP/NT 763-C2 and the accompanying note.

[1] [ανθροποπατως] ‘Anthropopathos’ – in the human manner. This term also appears at RP/NT 763-E1; see the accompanying note.

[2] [ens realissimum] Baumgarten, §807, notes that all realities are “truly positive” (vere positiva) (§36), that all realities in a being are compossible, and that the most perfect being is the most real being (§806), concluding that the “totality of all realities” (omnitudo realitatum) belongs to the most perfect being.

[3] [keine privation] This same example is used in Kant’s Only Possible Argument (AA 2: 85-86):

“The thrust of a body or the force of cohesion are, without doubt, something truly positive, similarly, in the sensations of the mind, pain is never merely a deprivation. A confusion has seemingly justified such an idea. It is said: reality and reality never contradict each other, for both of them are true affirmations; as a consequence, they do not conflict with each other in the subject either. Now, although I concede that there is no logical contradiction here, the real repugnancy is not thereby cancelled.” [Walford tr.]

Kant’s likely target here is Baumgarten, §807.

[4] [Ens perfectissimum] Baumgarten, §806, argues that “the most perfect being is the most real being.”

[5] [Baumgarten] Baumgarten, §808, argues that the most perfect being cannot include any negation, since a negation is the denial of some reality, and the most perfect being has the most realities. Kant is rejecting this inference.

[6] [Judaeo peregrinante] Kant uses this same example in the Only Possible Argument (AA 2: 76-77):

“The Omniscient certainly knows all the determinations which would inhere in such a person, if he were to exist, even though he does not actually exist. Without doubt, the eternal Jew, Ahasuerus, is, in respect of all the countries through which he is to wander and all the times through which he is to live, a possible person.” [Walford tr.]


Textual Notes
[RP/NT 796-808]

[Here is a mark-up key for the transcription.]

[a] In a darker ink but in the same hand, a '32)' is written in the top-left corner, above 'Kant'.

[b] An 'ist' is crossed out.

[c] A small sign that looks like a backwards 'N' and placed like a punctuation mark is written after 'Kobolds', as well as after 'Männerchen' later in the line.

[d] This parenthetical remark occurs three lines later in the manuscript, but is inserted here with a sign.

[e] An '˚und' is crossed out, followed by an insertion sign and phrase ("historie des Sohnes eines Prediger in der Wetterau") that is inserted three lines above.

[f] An 'Anmerkung' is written here, indicating where the long note in the left margin (concerning the Duke of Buckingham) should be inserted.

[g] Two insertion signs (upright-'F') appear here, the first with three flags.

[h] The following three lines of text is inserted here with a sign (slanting-'F' with two flags); in the manuscript, it is found six lines down.

[i] A '@Bann@' is crossed out.

[j] The following line is inserted with a sign (slanting-'F' with three flags), and immediately follows the previous insertion.

[k] A '@Kirch@' is crossed out.

[l] A 'Br' is crossed out.

[m] '˚Der' is written above a crossed out 'gr'.

[n] Text following this, and written in a dark black ink, is a poem fragment unrelated to the notes on metaphysics: “Im Tanze, der mit innerl.ich Gesang / ˚der @Z.eit / zur@ Mannl.iche den Jungl.liche Zwang, ˚.und in die Weiber ¿¿ Klang.”

[c] '33.' is written in the top-right corner (above 'Begriff') in the same ink.

[d] A '(1' is crossed out.

[e] Theol.ogia revel:elata is surely a miswrite; 'Theologia naturalis' is intended.

[f] The following text is written in a light-brown ink; the text above was a dark-brown bordering on black.

[g] An underlined 'p' follows 'est', and then a gap in the text before 's.ive, as though for a word to be filled-in later.

[h] The 't' in 'könnten' is crossed out.

[i] A '˚sondern' is crossed out.

[j] A 'contradicirten' is crossed out.

[k] Reading 'aber' as 'abend'.

[r] A 'non ente' is crossed out.

[s] A short line is drawn under this text, in black ink (darker than that used at the top of the page), followed by unrelated text, in the same black ink, down to the bottom of the page. This is the same ink, and the text concerns the same theme, as at the bottom of the previous page: “Im Tanze, der das ein Jünglings brüst …”
