Heilbroner, Robert Rather than projecting the shadow of Tomorrow’s unknowable realities, I propose to ask whether it is imaginable-I stress this crucial word-to exercise effective control over the future-shaping forces of Today. This rescues us from the impossible attempt to predict the shape of Tomorrow, and leaves us with the somewhat less futile effort of inquiring into the possibilities of changing or controlling the trends of the present. . . Can this intrusion of science and technology be bounded, conﬁned to its needed applications, and kept from sucking the life out of our engagement with nature and with one another? I ﬁnd that difﬁcult to imagine.
