The selected excerpts of letters are essential complements of the other texts for bridging the gap between his theoretical principles and strategic actions. This Chapter allows us to realise, in real-time, during successive events, the unusual degree of Miranda’s capacity for analysis and vision, showing his permanent and selfless struggle not only to achieve independence in his homeland but also his concern to insert it into an international alliance to strengthen democracy, the “ius gentium” and peace. The consistency and the constant ethics of Miranda’s attitude particularly stand out. Compared to W. Pitt’s British behaviour, his integrity and ethical approach are evident in his letters, allowing readers to compare their respective geopolitical capacity to foresee the events. The 54 documents are presented in three successive periods, corresponding to Miranda’s residence places: London, Paris, and the Americas.
