What does jefferson mean by saying that the people do not change governments for light reasons?

the people's duty are to stand up and alter or abolish the government. they have to form a new government that applies to their own society and content. what does jefferson mean by saying that people do not change governments for "light reasons"? the government is not completely altered because of silly reasons.

the supreme court can hear any case it wishes as long as four justices agree to hear it.
