Translation of "sorburu" into English

Inor ez da besterik gabe, hau da, arrazoi pribaturik gabe, jeneralburu, edo anarkista, edo sozialista, edo erreakzionario egiten eta mundua nola edo hala aldatu duten gertaera handiek —prestuak nahiz doilorrak—, beti gertaera erabat hutsalen bat izan dute sorburu, guretzat ezezaguna.

No one becomes a generalissimo, or an anarchist, or a socialist, or a reactionary simply, that is, without private reasons, and the great events that have changed the world in one way or another—whether noble or vile—always have their origin in some completely insignificant / trivial event, unknown to us.
