Bava Batra

he [the buyer] can say unto him: If you had not imposed upon me, you would have had no right to withdraw; can you have the right to withdraw now that you have imposed upon me? And the Tanna [of our Mishnah, who taught that 'if wheat was sold as] GOOD AND IT TURNED OUT TO BE BAD, THE BUYER MAY WITHDRAW,' but not [inferentially] the seller,  confirms [what has just been said]. R. Hisda further stated: [If] one has sold to another what was worth six for five and the price fell  to three, the seller, since he has been imposed upon, may withdraw, but not [so] the buyer; because [the seller] can say unto him: If you had not imposed upon me you would have had no right to withdraw; can you have the right to withdraw now? And the Tanna [of our Mishnah, who taught that 'if wheat was sold as] BAD AND IT TURNED OUT TO BE GOOD, THE SELLER MAY WITHDRAW,' but not [inferentially] the buyer,  confirms [this statement]. What does he  come to teach us? [Surely] this [statement of his may be inferred from] our Mishnah! — If  [it had to be inferred] from our Mishnah, it could have been said that [in the cases dealt with in the statement] of R. Hisda, both  may perhaps withdraw; and [that the first clause of] our Mishnah comes to teach us that  the buyer may withdraw;  for [without this Mishnah] it might have been said that [he cannot], because it is written: 'It is bad, it is bad', saith the buyer. [IF ONE HAS SOLD WHEAT AS] DARK-COLOURED AND IT TURNED OUT TO BE WHITE, etc. R. Papa said: Since white is given [as the contrast of the other colour]  it may be inferred that the sun is dark-red.  This can be proved [from the fact] that the sun is red at sunrise and at sunset. The reason why we do not see it [red] all day, is [because] our eyesight is not strong [enough].  An objection was raised: And the appearance thereof be deeper than the skin,  [that means], like the appearance of sunlight [which is] deeper than the shadow.  Surely there  [the appearance] was white,  [how, then, could the sun be said to be red]?  — Like the appearance of the sun [in one respect], and not like the appearance of the sun [in another respect]. Like the appearance of the sun, [in] that it is deeper than the shadow; and not like the appearance of the sun [in another respect], for there,  it is white and here  it is red. But according to our previous assumption,  is not the sun red at sunrise and at sunset?  — [It is red] at sunrise, because it passes by the roses of the Garden of Eden;  at sunset, because it passes the gate of Gehenna.  Others reverse [the answer]. [IF LIQUID HAS BEEN SOLD AS] WINE, AND IT TURNED OUT TO BE VINEGAR … BOTH MAY WITHDRAW. Must it be said that our Mishnah is [in agreement with] Rabbi and not [with] the Rabbis?  For it has been taught:
