Comment on Did Dr. Krashen Commit Self-Plagiarism? by Neza

Plagiarism is “an act or instance of using or closely imitating the language and thoughts of ANOTHER author without authorization and the representation of that author’s work as one’s own, as by not crediting the original author.” Thus “self-plagiarism” is a contradiction in terms, for starters, unless we go the Alice In Wonderland route of arbitrarily re-defining words as we please.
In any case, the central ethical violation of plagiarism is stealing someone else’s work – how can you steal from yourself. “Double-dipping” may be unethical or in breach of the rules, but it hardly seems equivalent to theft.
