In Megillah 4.6, R. Judah says: "He that has never seen the light may not recite the Shema' with its Benedictions."
I interpret "has never seen the light" as "blind" (rather than lacking inspiration or worthiness) since the previous line talks about how the blind, specifically, "may recite the Shema with its Benedictions and recite."
Why did R. Judah not see the blind fit for reciting the Shema with their benedictions? Did he perceive their blindness as a blemish, and therefore an emblem of their lack of unworthiness? Does his standpoint (concerning the blind and recitations of Shema) hold any influence on any sects today? I hope not, but I'm just curious.
