The art of self-transformation for the sake of developing practical capabilities seems to have a similar content in the most varied historical circumstances. The Mamluks and the Normans suffered defeat because they failed to open up and readjust the organizational and social contexts of warfare. The Seljuqs succeeded because they did just that. The West African coastal kingdoms used an extraneous technological advantage to avoid having to change radically. But they could neither go on the offensive against the savanna states nor prepare themselves to resist their European patrons and trading partners.
In all these instances success seems to have required the dissociation and recombination of available models of the organizational and social context of military activity. To have succeeded would not have meant, for the Mamluks, becoming like the Ottomans; it would have meant creating an order that never existed before. To possess the alien, you must change it.
