פירוש על ברכות 33:11

One who does them not for their own sake, preferable for him had he not been created - What about what the statement of Rav Yehuda in the name of Rav in the perek Makom Sh'Nahugu (Pesachim 50b) "A person should always do Torah and mitzvot even if he doesn't do them for their own sake, for thought doing them not for their own sake he will come to do them their own sake"? It is possible to say that over here we are dealing with someone learning only to vex his friends whereas over there it is someone who learns with the motivation that others should honor him.

Some edd. read : all that learn thereafter.

He who learns only to display his knowledge by contradicting others is not one who practises Torah for its own sake.

See above p. 109 n. 2.
