This collection focuses on the ontology of space and time. It is centred on the idea that the
issues typically encountered in this area must be tackled from a multifarious perspective
paying attention to both a priori and a posteriori considerations. Several experts in this area
contribute to this volume:G. Landini discusses how Russell's conception of time features in his
general philosophical perspective D. Dieks proposes a middle course between substantivalist
and relationist accounts of space-time P. Graziani argues that it is necessary to provide an
account of the synthetic procedures implicit in the recourse to diagrams in Euclid's Elements
while E. Mares comes to the conclusion that in Euclid's Elements we should treat the parallel
postulate as empirical and the postulate that space is continuous as a priori.M. Arsenijevic M.
Adzic present an important formal result concerning two theories of the infinite
two-dimensional continua which sheds new light on the current dispute between gunkologists and
pointilists F. Orilia discusses two problems for presentism one regarding the duration of the
present and the other related to Zeno's paradoxes. A. Iacona delves deep into logical matters
by focusing on the so-called T×W modal frames in order to deal with the
deteterminism-indeterminism controversy. D. Mancuso outlines a non-standard temporal model
compatible with time travel and V. Fano G. Macchia discuss time travels in the light of an
important foundational principle of modern cosmology Weyl's Principle.
