Changes

• This definition is problematic as it inadvertently qualifies ''every'' change in a mosaic as scientific. However, it is clear that not all changes in a mosaic are scientific; some changes might take place in violation of the laws of scientific change. By current definition, even the most outrageous cases of politically influenced changes in a mosaic (e.g. the Lysenko case) quality qualify as scientific. Now, how can the definition of "scientific change" be modified to exclude ''unscientific'' changes in a mosaic? In particular, how can it be accomplished without turning the laws of scientific change into tautologies?
