The work of Father Teilhard de Chardin is an example of what the introduction of the prehistoric question does to the human sciences when it enters their disciplinary field: it obliges them either to reformulate themselves or to be at odds with the science of their time. Thus the primary virtue of Teilhard’s work, beyond the theses he may have supported, is to have been, if not the first, at least one of the first men of the Church, to envisage a theology that takes note of this.
