And at the end of it, Fray Servando Fugitivo y Héroe carried out research on the thoughts and actions of this Mexican hero, to specify the project of an interpretation on this matter and culminate it with a philosophy of history.
His thoughts can be summed up when he said:

“We must accept that authentic political and social struggles are, in most cases, harsh and sacrificial, that not all those who feel called are willing to endure the play of forces. Politics, in the end, is the instrument through which it must be possible to bring happiness to the people, but never a resource for personal or group benefit.”
