Final answer:
Vaillant's work indicated a slow and steady change, rather than a crisis. This concept can be applied to various historical contexts such as the transition from feudalism to capitalism in Europe during the Middle Ages.
Step-by-step explanation:
Vaillant's work indicated a slow and steady change, rather than a crisis. This concept can be applied to various historical contexts. For example, in the field of history, the idea of slow and steady change is evident in the development of societies, political systems, and cultural norms over time. It contrasts the notion of sudden and dramatic shifts. One example of this is the gradual transition from feudalism to capitalism in Europe during the Middle Ages. Instead of a sudden revolution, this change occurred gradually, influenced by economic, social, and political factors.
