Hehe, the usual response to idealism is to drop a rock onto the propounder's
finger, and then ask them if they still do not believe in material objects.

Something that kicks back (has an effect on the universe). Note that this
excludes "epiphenomena" such as qualia or some interpretions of
consciousness, since it appears that the universe would keep running exactly
the same way without them.
