Schopenhauer makes a fine alternative if one doesn't find Bergson's vitalism to taste. The question boils down to whether there is a role for "negativity" in Bergson (perhaps even as an attitude, pessimism) or whether positive creative-addition debars that automatically.
Can there ever be real loss in a universe which preserves all in the objective immortality of the past? This Bergsonian/Whiteheadian view of a cumulative durational succession would be contrasted with Schopenhauer's belief that, "Time is that by virtue of which everything becomes nothingness in our hands and loses all real value."
