Sentence:  For as, whatever the perfectness of the educational system, there must remain infinite differences between the natures and capacities of men ; and these differing natures are generally <WSD>rangeable</WSD> under the two qualities of lordly, (or tending towards rule, construction, and harmony), and senile (or tending towards misrule, destruction, and discord) ;  and, since the lordly part is only in a state of profitableness while ruling, and the servile only in a state of redeemableness while serving, the whole health of the state depends on the manifest separation of these two elements of its mind; for, if the servile part be not separated and rendered visible in service, it mixes with, and corrupts, the entire body of the state; and if the lordly part be not distinguished, and set to rule, it is crushed and lost, being turned to no account, so that the rarest qualities of the nation are all given to it in vain. 
Meaning of the word marked with <WSD> tags:  Arrangeable; classifiable.
