HN people are basically redditors. Most have zero critical though. The couple people who have doubts that a deaf, dumb, blind girl could have visual metaphors in her writing are downvoted (the real history is that keller was deaf, dumb, and blind (basically a vegetable), and that anne sullivan used keller as a mouthpiece). The pictured comment was subsequently purged.

Seriously, you are expected to believe the vegetable wrote this:
>With a little ingenious reasoning one may see in the material world simply a mirror, an image of permanent mental sensations.
