_P'sachim_, fol. 54, col. 1.

"Every one has two portions, one in paradise and another in hell."
Acheer asked Rabbi Meyer, "What meaneth this that is written (Eccl. vii.
14), 'God also has set the one over against the other'?" Rabbi Meyer
replied, "There is nothing which God has created of which He has not
also created the opposite. He who created mountains and hills created
also seas and rivers." But said Acheer to Rabbi Meyer, "Thy master,
Rabbi Akiva, did not say so, but spake in this way: He created the
righteous and also the wicked; He created paradise and hell: every man
has two portions, one portion in paradise, and the other in hell. The
righteous, who has personal merit, carries both his own portion of good
and that of his wicked neighbor away with him to paradise; the wicked,
who is guilty and condemned, carries both his own portion of evil and
also that of his righteous neighbor away with him to hell." When Rav
Mesharshia asked what Scripture guarantee there was for this, this was
the reply: "With regard to the righteous, it is written (Isa. lxi. 7),
'They shall rejoice in their portion, therefore in their land (beyond
the grave) they shall possess the double.' Respecting the wicked it is
written (Jer. xvii. 18), 'And destroy them with double destruction.'"

resolved philosophically by their master. Others had maintained
that you could not think a thing but through its opposite; he
first maintained it could not exist but through its opposite,
