Is it paradoxical to say "I dont exist" since when you say "I", it represents mere existence and when you say "dont exist" it means "Mere existence dont exist" but in the beginning you have asserted your existence by saying "I".Unless you are sure and certain of your existence you wont say "I" and then you say "dont exist" which appears to be contradictory.So isnt it paradoxical when you say "I dont exist"
