Ciência, tecnologia e "world view" (Weltanschauung)


“[T]he main influence of science on modern man has not been, as is often supposed, through the advancement of technology; it has come, rather, through the imaginative effects of science on our world view. . . . During the past eighty years or so the progress of science has become a mainspring of technical progress, and this has changed many of our habits, improved our material welfare, and brough...t us certain special problems; but it has not had anything like the profound effect upon our conception of ourselves as human beings that Darwinism has had, and Darwinism has been responsible for no technical progress.” -- Michael Polanyi and Harry Prosch, Meaning (Chicago: University of Chicago Press, 1975), pp. 104-05.

“We have no strict proofs for any parts of science. The radical import of this fact is usually blunted by contentions that the statements of science are only probable and merely tentative; but this is an exaggeration and is in any case irrelevant. The fact is that not only do we accept and vitally rely on scientific observations (we do not really treat them as only probable or tentative), but we d...o so on the ground of nonstrict criteria. Our reliance on the validity of a scientific conclusion depends ultimately on a judgment of coherence; and as there can exist no strict criterion for coherence, our judgment of it must always remain a qualitative, nonformal, tacit, personal judgment.” -- – Michael Polanyi and Harry Prosch, Meaning (Chicago: University of Chicago Press, 1975), p. 100.
