Guest article: Self-plagiarism in philosophy

A quip heard in the hallways of some philosophy departments goes like this: when someone publishes a new book, a colleague says, “Congratulations! So, what are you calling it this time around?” With every witticism, there is some level of truth; my professional discipline of philosophy has been somewhat sluggish in addressing the problem of self-plagiarism.

Case

Suspected unattributed text in a published article

16-21

An article was published in July. In October, a corrigendum was published to correct large sections of unattributed text. Two weeks later the journal and publisher received a complaint from a reader who accused the author of the published article of using text from an unpublished collaborative manuscript on which the published author was participating.

Case

Profusion of copied text passages

15-16

Recently, our journal has introduced systematic analysis of all submitted manuscripts for plagiarised text, using anti-plagiarism software. We had noticed increased incidences of recycling of existing text which is why we introduced the systematic check. It turns out that a large proportion of the submitted manuscripts (an estimated 30–50%) yield positive results, with copy values of somewhere in the region of 25% to >35%.
