It is clear from this letter that Voltaire thinks very highly of Frederick. Toward the beginning of the letter he says that Frederick is "counted among the kings" but is "more than them". Voltaire compliments Frederick on performing big actions, and being wise, and writing poetry and music with ease. He writes of his hope that Frederick will "strengthen Europe, as it has shaken." The letter ends with Voltaire saying- "The philosopher king is exactly what the philosopher who is not king tried in vain to become."
