What does Guevara claim the first two lessons of Guerrilla warfare are meant to address in Chapter I of the nonfiction book, General Principles of Guerrilla Warfare?

The first two lessons are meant to be a challenge to what Che calls the "pseudo-revolutionary" parties that wait for the conditions of revolution to arise rather than creating the revolution themselves. In this way, Che believes that the once the civil government has lost its legitimacy, a guerrilla force can take the subjective conditions of the revolution and make them objective in actual revolutionary struggle.
