Hello, I'm having some difficulty with meaning of the sentence below. Does the "positive work" refer to the doings of the General Staff? I'm kinda confused because the author seems to criticise it (General Staff) in his subsequent words. Or does he say that such work about the history of General Staff would be a positive/useful (book). Thank you for your help. "Seeckt himself not only recalled the past but foreshadowed the future when he wrote — “A history of the General Staff...would be a history of quiet positive work; it would tell of arrogance and haughty acquiescence, of vanity and envy, of all human weaknesses, of the fight between genius and bureaucracy, and of the hidden causes of victory and defeat."
