My take on what it means to be sane(video)

[caspex]

TLDW; You cannot determine yourself as sane because you are the ultimate comparison and the ultimate authority(who uses his/her sanity to determine whether he/she is sane or not). This means the word sanity itself is empty. It is just what you say it is. When contemplating Sanity, you break into Insanity, Insanity with a capital I.
