Abstract

“Experience and the conception of the world in science in transition to modern times” is the general subject. There are two different points to be made clear, i.e.1. That the conception of the world had to be made imaginable by art before it could be taken over by science. The central perspective dates back to about three centuries before the time Descartes developed the co-ordinate system.2. Furthermore it should be taken into account that it was first of all due to the lead of the painters that the possibility of making experiences had changed. In a space opened by a perspective view and seemingly thus appearing as measurable even the painted figures acquire a new reality. Due to his anatomic studies Leonardo could treat the natural movement of the figures shown in his paintings.It was the artists who first of all investigated optics and anatomy before relations could be measured with the aid of scientific methods ami before quantities — instead of qualities — could become the base of unbiased science, as called for by Galilei in 1623
