The human intellect, in its ineptitude to pursue what is vital, immobilizes time within an ever-artificial present. Such present is pure nothingness — a nothingness that cannot even succeed at truly separating past from future. It seems indeed that the past carries its forces into the future, and that the future is necessary as an outlet for forces issuing form the past. A single sweeping life force, an identical élan vital, would thus suffice to consolidate duration. Thought, as a fragment of life, should not impose its rules upon life. Devoted as it is to the contemplation of static being, of spatial being, the intellect must guard against misunderstanding the reality of becoming… It then becomes necessary for us to take time as a whole, if we are to grasp its reality. Time is at the very source of the élan vital. Though life may be showered with flashes of insight, it is truly duration that explains life.
