The possible becomes real only through a person’s project, not as pre-existing logical possibility

Evidence

The project of the For-itself toward the future which it is is a project toward the In-itself. In this sense the For-itself has to be its future because it can be the foundation of what it is only before itself and beyond being. It is the very nature of the For-itself that it must be “an always future hollow.” For this reason it will never have become, in the Present, what it had to be, in the Future. — Jean-Paul Sartre, Being and Nothingness, 453 (#expands, via linked claim)

The Future thus defined does not correspond to a homogeneous and chronologically ordered succession of moments to come. To be sure, there is a hierarchy of my possibles. But this hierarchy does not correspond to the order of universal Temporality such as will be established on the bases of original Temporality. I am an infinity of possibilities, for the meaning of the For-itself is complex and cannot be contained in one formula. But a particular possibility may be more determinant for the meaning of the present For-itself than another which is nearer in universal time. For example, the possibility of going at two o’clock to see a friend whom I have not seen for two years—this is truly a possible which I am. But the nearer possibilities—the possibilities of going there in a taxi, by bus, by subway, on foot—all these at present remain undertermined. I am not any one of these possibilities. — Jean-Paul Sartre, Being and Nothingness, 456 (#corroborates, via linked claim)
