Regardless of which series is cited, Star Trek was always at its best when it reflected or commented on the human condition. Captain Jean-Luc Picard was a particularly skilled and erudite representative of humanity as portrayed in The Next Generation series, as the writers of those stories gave him plot-lines and words to give expression to what humanity aspires.
That said, here are a handful of examples of what Capt. Picard had to say about himself, his species, his mission, those things which resonated to him. Please enjoy.
