Pessimism of the intellect, optimism of the will

A number of scholars have suggested that, although optimism and pessimism might seem like opposites, in psychological terms they do not function in this way. Having more of one does not mean you have less of the other. The factors that reduce one do not necessarily increase the other. On many occasions in life we need both in equal supply. Antonio Gramsci famously called for "pessimism of the intellect, optimism of the will": the one the spur to action, the other the resilience to believe that such action will result in meaningful change even in the face of adversity.
