The "crisis of men" refers to the idea that men, particularly in the contemporary societies, are experiencing a significant social, psychological and economic decline relative to the past generations.

The basic structure doctrine is a doctrine of legal and political theory according to which there are limits on the power of the legislative branch to amend the constitution. According to this doctrine, while the legislature may amend, alter, or revise most provisions of the Constitution, it cannot change the Constitution's basic structure or core features.

According to the doctrine, courts can prevent such changes to the constitution by the legislature by declaring them to be unconstitutional and void.
