“Moses Maimonides, the Jewish scholar of the twelfth century, argued that hope is belief in the ‘plausibility of the possible’ as opposed to the ‘necessity of the probable.’ While it is always ‘probable’ that Goliath will win, it is also true that sometimes David wins, a sense of the ‘possible’ that we experience in our own lives as well. Hope emerges from this sense of possibility, freeing us from the shackles of probability.”
