Derrida, 'Differance'

“the possible that is presently impossible”

When describing what ‘’to differ’ actually means in the first paragraph of the article, this quote is used. Although I can’t quite grasp what this quote means, I know it is taking on a word that is extremely hard to define in my eyes. After reading the blog by Scarlet Wishes, I was a lot less confused on what Derrida was trying to say.
I like the idea of relating this to Barthes’ idea of ‘the gap’. I think to be different means something is not there. If something were normal, it would be composed of everything we have been taught to think is normal. It goes a long with the notion that 5 minus 2 equals 3. Three is different than five because it is worth 2 less. But what makes something different? How do we know it is real?
When something that is different, it does not mean that it is a bad thing. Yes 5 might be more than 3, but when we look at the notion of filling in the gap, Barthes understood it as something good and informative. I still find myself confused on many of the sentences that are in the article, I’m hoping today’s lecture will clear it up for me.
