Fear and Power

As Spinoza discusses in II, 10-11 of Political Treatise, a primary example of irrational political motivation is Fear.  Now, because in submission to external threats the cause is the latter, fearfulness is also powerlessness.  On the other hand, fearfulness can also be diagnosed as motivated by one's survival instinct, and, hence, according to Spinoza's analysis, is, in fact, an expression of one's natural power.  However, one significant result of the Ethics is that the only response to threat that is truly an expression of one's persistence in being is resisting Fear, accompanied by acquiescence to one's fate.  Thus, the irrational response to a threat is the powerless response, which casts further doubt on Spinoza's attribution of 'Natural Right' to irrational behavior, e. g. in II, 8.
