This is the definition of paradox:" An assertion that is essentially self-contradictory, though based on a valid deduction from acceptable premises"
But I believe, there is much more to it. Each half of a paradoxical contradiction is necessary for the whole, it is a “symmetry which is broken”,
paradoxes tap directly into the intuitive depth of knowing.
As do poetry and music.
"Only in silence the word,
only in dark the light."
"He who loses his life shall find it"
"There would be no dance and there is only the dance."
Some from recent TED conversations:
'Objectivity is the illusion of any subject."
"There are absolutely no absolutely true statements."
Aristotle's "reaffirmation through denial".
"we are all students and teachers in this earth school"
the expression "one-many" /I love it!/
“everything is both in time and in stillness. It is a changeless change.”
I am sure there are a lot more, and I ask the TED community to post here your paradoxes or phrases, expressions with paradox depth.
Quotations with your comment or without. Everything will be of great value.
