Even the transformation from a quantitative to a qualitative change and
the negation of negation are both unifications of contradictions. However you
argue, they are still struggles of opposites. Dialectics can be made monistic,
never pluralistic. Nature and society are full of contradictions. As soon as a
contradiction is resolved, a new one emerges. There is no world or society
without contradictions. Sometimes we may not be able to name a specific contradiction, but it exists all the same. Contradictions are the motivating force
of the development of everything. This has been so in the past, is so at present,
and will be so in the future.
