From pages 116-124 of “Creative Vow as the Essence of Fatherhood” in Homo Viator by Gabriel Marcel (1965):
Fatherhood … only exists as the carrying out of a responsibility, shouldered and sustained. …It utterly denies its own nature when it is the mere blind generation of a being not only incapable of providing for his progeny and guiding their spiritual development, but of realising and acknowledging the obligations he has undertaken towards them. It is probably in contrast with such inertia and blindness that we can best understand what the pure act of fatherhood should be. …This pure act is inconceivable without what I proposed to call the væu créateur.
…This væu créateur is no other than the fiat by which I decide to put all my energies at the service of this possibility which is already imposing itself upon me, but only upon me, as a reality, so that I may transform it into a reality for all, that is to say into an established work. This means that the væu, far from being reduced to a mere wish, has the character of an engagement and a decision. But this engagement or this decision is not made simply within my own being, something transcendent is involved, however indistinct my consciousness of it may as yet be.
…It is at bottom a question of spontaneous confidence in life which can almost equally be regarded as a call or as a response. It is this, and this alone, which enables man to establish his roots in the universe and to develop to his full stature.
…We have to lay down the principle that our children are destined, as we are ourselves, to render a special service, to share in a work; we have humbly to acknowledge that we cannot conceive of this work in its entirety and that a fortiori we are incapable of knowing or imagining how it is destined to shape itself for the young will it is our province to awaken to a consciousness of itself. We can see clearly enough that the væu créateur implies the combination of a deep personal humility and an unshaken confidence in life, conceived of not as a natural force but as an unfathomable order, divine in its principle. Now it is exactly the opposite combination which tends most often to be effected before our eyes, that is to say a maximum of personal pretension associated as we have seen with a radical agnosticism concerning life, its value and its meaning.
…It becomes possible to understand the fundamental nature of the væu créateur, wherein we believe we have found the essence of fatherhood to lie. It is the quivering anticipation of a plenitude, of a pleroma in the bosom of life, no longer an endless improvisation of disappointing variations on a few given themes, [that] will be satisfied, concentrated and reassembled around the absolute Person who alone can give it the infrangible seal of unity.
