25 de Abril. Sempre?

"As a rule, some people, such as Jacobins, tend to be more enthusiastic about revolutions than others, such as monarchs. Another fairly reliable rule is that revolutions abrupt enough to be associated with a single year (1642, 1789, 1848, 1917) tend to cause trouble but rarely bring lasting change. By contrast, revolutions gradual enough to be associated with a name (Renaissance, Reformation, Industrial Revolution) often do have enduring effects. A third rule, or hypothesis, might be that revolutions seem never to be entirely for the better or the worse, but somehow manage to combine both."
