" There have always been those who would champion the merits of perception, instinct, or faith over Empirical Truth. But facts are immutable, regardless of who or what perceives them. Power will always belong to the one who knows them. To one accustomed to small triumphs, every victory is great. It is in my gift, and in yours, to see beyond. "

― David Guymer , Lion El'Jonson: Lord of the First (The Horus Heresy: Primarchs, #13)
