“That we set aside all hitherto prevailing habits of thinking, that we recognize and tear down the intellectual barrier with which they confine the horizon of our thinking and now, with full freedom of thought, seize upon the genuine philosophical problems to be set completely anew made accessible to us only by the horizon open on all sides: these are hard demands. But nothing less is required.”
― Edmund Husserl, Ideas

“Der Wald ertönt von tausendstimmigem Leben,
Tal aus, Tal ein ist Nebelstreif ergossen,
Doch senkt sich Himmelsklarheit in die Tiefen,
Und Zweig und Äste, frisch erquickt, entsprossen
Dem duft'gen Abgrund, wo versenkt sie schliefen;
Auch Farb' an Farbe klärt sich los vom Grunde,
Wo Blum' und Blatt von Zitterperle triefen –
Ein Paradies wird um mich her die Runde.”
― Johann Wolfgang von Goethe, Faust, Zweiter Teil

“I could illustrate the second approach with the image of a nut that one must open. The first parable that came to my mind earlier, is immersing the nut in an emollient, perhaps water, and rubbing it occasionally, so that the water penetrates better, and we let time do its work. The shell softens over the course of weeks or months; when the time is ready, a little pressure from the hand suffices, and the nut opens up like that of a ripe avocado! Or even better, one lets the nut mature under the sun and under the rain and maybe even under the winter frosts. When the time is ripe a delicate sapling will emerge from the substantial flesh that will have pierced the shell, as if playing - or to put it better, the shell will have opened on its own, to let it pass.”
― Alexandre Grothendieck

“Analogy (qiyās al-tamthīl) and the categorical syllogism (qiyās al-shumūl) are equivalent. Certainty (yaqīn) and probability (ẓann) differ only according to the subject matter [of the premises]. If the specific subject matter is certain in one, it is certain in the other, and, if it is probable in one, it is probable in the other.”
― Ibn Taymiyyah, The Rebuttal of the Logicians
