Derech Eretz Before Torah
חטא דור המבול הי' בבחי' ד"א שקדמה לתורה כי יש ב' אלפים תוהו עד האבות שהתחיל ב' אלפים תורה.
The sin of the generation of the Flood was in the aspect of “the knowledge that precedes Torah,” for there are two thousand years of chaos until the Patriarchs, when the two thousand years of Torah began.
The Sefat Emet explains that the generation of the Flood operated from a pre‑Torah state—an unrefined stage of existence lacking the structure Torah brings.
לכן גם צדקת נח הי' בבחי' ד"א.
Therefore Noah’s righteousness, too, was in the aspect of that pre‑Torah knowledge.
Noah’s virtue belonged to the same developmental stage; it was moral integrity prior to full Torah revelation.
ואיתא בתדב"א ע"פ ויגרש את האדם כו' לשמור דרך עה"ח דרך זו ד"א עה"ח זו תורה מלמד שד"א קדמה לתורה.
And it is taught in Tanna Devei Eliyahu on the verse “He drove out the human… to guard the way to the Tree of Life”: “The way” is this pre‑Torah knowledge, “the Tree of Life” is Torah, teaching that this knowledge preceded Torah.
The midrash identifies a preparatory human capacity—moral and spiritual discipline—that precedes access to Torah.
נ"ל כי זה נעשה אחר החטא כי מקודם הי' מוכן מיד לתורה ואחר החטא נעשה כן שלא יהי' כ"א זוכה מיד לתורה כענין שכ' מאן דנצח לחויא כו'.
It seems to me that this arrangement came only after the sin, for originally humanity was ready for Torah immediately, but after the sin it was arranged that not everyone would merit Torah at once, as it is written regarding one who conquers the serpent, etc.
The Sefat Emet proposes that before Adam’s sin the human condition did not require this preliminary stage; the fall introduced the need for gradual preparation.
כי בחי' ד"א הוא תיקון הגוף והמידות.
For this pre‑Torah state is the rectification of the body and the character traits.
This stage refines the human being so they can later receive Torah properly.
לכן אח"כ הוצרך בחי' נח כנ"ל.
Therefore afterward the world required the aspect of Noah, as explained.
Noah embodied this necessary preparatory purification for humanity post‑sin.
ולכן אמרו מי שפרע מדור המבול כו' שעיקר חטאם הי' בבחי' ד"א כנ"ל.
And thus they said: “He who exacted punishment from the generation of the Flood…”—for their primary sin was in that pre‑Torah aspect, as noted.
Their failure lay in corrupting the very foundational moral framework meant to lead toward Torah.
The Sefat Emet teaches that both Noah’s righteousness and the Flood generation’s sin belong to a primordial stage preceding Torah, created after the primordial sin to refine human character before divine revelation.
