,Geometry and “Metaphysics of Space” in Gauss and Riemann,en as an axiom and formulated in the following terms: “That, if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles”. (Heath 1956, p. 20)

0068-0346 of knowledge was decidedly unitary, but, in the period between1790 and 1840, the special emphasis it placed on observation andresearch led to an unprecedented accumulation of data, accompanied bya rapid growth in scientific specialization. An example of thetensions created by this development is to
