Thukydides ist der Begründer der politischen Geschichtsschreibung. Er war ungefähr 30 Jahre alt, als 431 v. Chr. der Peloponnesische Krieg ausbrach, jener jahrzehntelage Machtkampf zwischen Athen und Sparta, an dessen Ende Athen - und mit ihm die Demokratie - gegen das spartanische Königtum unterlag. Thukydides hatte hier sein Lebensthema gefunden. Doch bevor er zum Chronisten der Kämpfe zwischen den beiden Blöcken wurde, hat er selbst an ihnen teilgenomnmen. Im Jahre 425/4 v. Chr. bekleidete er das hohe militärische Amt des Strategen, (...) bis ein Misserfolg zu seiner Verbannung führte. Er lebte daraufhin 20 Jahre im Exil und kehrte erst nach Kriegsende nach Athen zurück. (shrink)

We present an epistemological schema of natural sciences inspired by Peirce's pragmaticist view, stressing the role of the \emph{phenomenological map}, that connects reality and our ideas about it. The schema has a recognisable mathematical/logical structure which allows to explore some of its consequences. We show that seemingly independent principles as the requirement of reproducibility of experiments and the Principle of Sufficient Reason are both implied by the schema, as well as Popper's concept of falsifiability. We show that the schema has (...) some power in demarcating science by first comparing with an alternative schema advanced during the first part of the 20th century which has its roots in Hertz and has been developed by Einstein and Popper. Further, the identified differences allow us to focus in the construction of Special Relativity, showing that it uses an intuited concept of velocity that does not satisfy the requirements of reality in Peirce. While the main mathematical observation connected with this issue has been known for more than a century, it has not been investigated from an epistemological point of view. A probable reason could be that the socially dominating epistemology in physics does not encourage such line of work. We briefly discuss the relation of the abduction process presented in this work with discussions regarding ``abduction'' in the literature and its relation with ``analogy''. (shrink)

In the present essay we attempt to reconstruct Newtonian mechanics under the guidance of logical principles and of a constructive approach related to the genetic epistemology of Piaget and García. Instead of addressing Newton’s equations as a set of axioms, ultimately given by the revelation of a prodigious mind, we search for the fundamental knowledge, beliefs and provisional assumptions that can produce classical mechanics. We start by developing our main tool: the no arbitrariness principle, that we present in a form (...) that is apt for a mathematical theory as classical mechanics. Subsequently, we introduce the presence of the observer, analysing then the relation objective–subjective and seeking objectivity going across subjectivity. We take special care of establishing the precedence among all contributions to mechanics, something that can be better appreciated by considering the consequences of removing them: the consequence of renouncing logic and the laws of understanding is not being able to understand the world, renouncing the early elaborations of primary concepts such as time and space leads to a dissociation between everyday life and physics, the latter becoming entirely pragmatic and justified a-posteriori, changing our temporary beliefs has no real cost other than effort. Finally, we exemplify the present approach by reconsidering the constancy of the velocity of light. It is shown that it is a result of Newtonian mechanics, rather than being in contradiction with it. We also indicate the hidden assumption that leads to the contradiction. (shrink)

This book covers the author's conception of God aside from any religion. He does not come from a religious view in order to transmit the truest conception of God that he is capable of because any religion, whatever it might be, always claims God for itself in an exclusionary fashion. In other words, you must be a follower of the chosen faith before God will accept you into his kingdom. Wells rejects this view. Any man or woman who accepts God's (...) love as one person connecting to their own creator, is fine. An intermediary, despite what they might crow from whatever pulpits they use, is not necessary. We are all God's children. We are all seeking the same God, so to be dogmatic within a certain exclusionary faith is small-minded and petty. If you want to grow up, spiritually, then this book is for you. (shrink)

Ist das menschliche Handeln vorbestimmt oder kann der Einzelne frei entscheiden? In Auseinandersetzung mit den Positionen von Chrysipp, Epikur und Karneades gelangt Cicero zur Auffassung, dass es für den menschlichen Willen keine von außen wirkenden und vorausgehenden Ursachen gebe, die diesen Entscheidungsprozess bestimmen. Die Mitte 44 v.Chr. begonnene und unvollendet gebliebene Schrift schließt sich unmittelbar an "De divinatione" und "De natura deorum" an.
