First of all, wedrifid didn’t say that “paradoxes are not contradictions”, he just said (correctly) that this particular contradiction is not a paradox.
Secondly:
A contradiction is the following: “A. The sky is blue”. “B. The sky is green.” One of the sentence is true, the other is false. No paradox here.
A (rather childish) paradox is the following: “A. Sentence (B) is true.” “B. Sentence (A) is false.” You can’t assign a truth-value to either (A) or to (B), without leading to a self-contradiction, making this set of two sentences paradoxical.
Paradoxes are not contradictions.… Anyone who gave me a minus should explain why.
