ABSTRACT It is commonly argued that Kierkegaard’s famous observation that life can be understood backward, but must be lived forward excludes the possibility of intellectual preparation to life. This article suggests the view that, while it is not the case that Kierkegaard has an elaborate vision of thinking about the possibilities of life one faces, he engages the notion of imaginary construction [experimentere] to propose existential prototypes for mental exploration that prepare us for life lived forward. It is concluded that (...) the person capable of imaginary construction has to be able to be firmly in control of the possibilities she faces. In Kierkegaard’s view, such a control requires the grasp of the opposite temporal directions – to be both looking at one’s past and future. Kierkegaard’s employment of such a double temporal vision of existence is modelled on Janus Bifrons, the two-faced god who is effectively able to simultaneously look both backward into the past and forward into the future.
