Vicious Circle

In Indian logic, one of the fallacies to be
avoided in constructing an argument. A
vicious circle occurs when a series of
things stand in a cause-and-effect relationship to one another, with any one of
them standing as both cause and effect.
For example, when “a” causes “b,” and
“b” causes “c,” (somewhere down the
line) “x” causes “a.” This is seen as an
extended case of self-residence—saying
that “a” is both cause and effect—and is
equally objectionable.
