Emily Dickinson Lexicon

BLIND, a. [Sax. blind; Ger. D. Sw. and Dan. blind; Sax. blendan, to blend and to blind. This is the same word as blend, and was so written by Spenser. See Blend. Obscurity is from mixture.]

1. Destitute of the sense of seeing, either by natural defect, or by deprivation; not having sight.
2. Not having the faculty of discernment; destitute of intellectual light; unable to understand or judge; ignorant; as authors are blind to their own defects. Blind should be followed by to; but it is followed by of, in the phrase, blind of an eye.
3. Unseen; out of public view; private; dark; sometimes implying contempt or censure; as, a blind corner. – Hooker.
4. Dark; obscure; not easy to be found; not easily discernible; as, a blind path.
5. Heedless; inconsiderate; undeliberating. This plan is recommended neither to blind approbation nor to blind reprobation. – Federalist, Jay.
6. In Scripture, blind implies not only want of discernment, but moral depravity.
