William Lane Craig modified Bertrand Russell’s Tristram Shandy example in order to derive an absurdity that would demonstrate the finitude of the past. Although his initial attempt at such an argument faltered, further developments in the literature suggested that such an absurdity was indeed in the offing provided that a couple extra statements were also shown to be true. This article traces the development of a particular line of argument that arose from Craig’s Tristram Shandy example before advancing an argument (...) of its own that attempts to fill in the relevant gaps so as to yield a new argument for the finitude of the past.

Călătoria în timp implică deplasarea într-un timp diferit de cel prezent, în trecut sau în viitor, în principiu fără o deplasare în spațiu cu referire la un sistem de coordonate local. Călătoria în timp poate fi făcută de un corp material care poate fi sau nu o ființă vie, și pentru care se folosește de obicei un dispozitiv special denumit mașina timpului. Călătoria în timp este un concept recunoscut în filosofie și știință, dar a cărui posibilitatea este foarte disputată, dând (...) naștere la numeroase paradoxuri atât în filosofie cât și în știință. Călătoria în timp este considerată de unii acceptată atât de relativitatea generală cât și de mecanica cuantică, dar există un consens unanim că nu este fezabilă cu tehnologia actuală. Problemele ridicate sunt diferite pentru călătoria în timp în trecu față de călătoria în timp în viitor. (shrink)

While Karl Popper’s philosophy of science has only few followers among modern philosophers, it is easily the view of science with the biggest impact on practicing scientists. According to Peter Medawar, Nobel laureate and eminent physiologist, Popper was the greatest authority ever on the scientific method. He praised the “great strength of Karl Popper’s conception of the scientific process,” a main reason for the praise being “that it is realistic—it gives a pretty fair picture of what goes on in real (...) life laboratories” (Medawar 1990, p. 100). Either explicitly or (more often) implicitly, many scientists subscribe to some version of simplified Popperianism, usually by adopting the demarcation criterion that a .. (shrink)

Problems of scientific cosmology only rarely occur in the works of Karl Popper. Nevertheless, it was a subject that interested him and which he occasionally commented on. What is more important, his general claim of falsifiability as a criterion that demarcates science from non-science has played a significant role in periods of the development of modern physical cosmology. The paper examines the historical contexts of the interaction between cosmology and Popperian philosophy of science. Apart from covering Popper’s inspiration from Einstein (...) and his views on questions of cosmology, it focuses on the impact of his thoughts in two periods of controversy of modern cosmology, the one related to the steady state theory and the other to the recent multiverse proposal. It turns out that the impact has been considerable, and continues to be so, but also that the versions of Popperian methodology discussed by cosmologists are sometimes far from what Popper actually thought and wrote.

In the last part of Ethics Spinoza introduces the doctrine of the intellectual love of God: God loves himself with an infinite intellectual love. This doctrine has raised one of the most discussed puzzles in Spinoza scholarship: How can God have intellectual love if, as Spinoza says, God is Nature itself? After examining existing.approaches to the puzzle and revealing their failures, I will propose a Neo- Confucian approach to the puzzle. I will compare Spinoza's philosophy with Neo-Confucian philosophy and argue (...) that we can develop a new approach to the puzzle by appealing to the comparison. I conclude that the intellectual love of God can be properly understood from different perspectives. From God's perspective it is understood as the creative power of God. From an individual's perspective it is understood as the essence of this very individual. Moreover, once we combine these two perspectives we can reach what I consider to be the correct interpretation of Spinoza' s view: Given that intuitive knowledge and action are one and the same the intellectual love of God should be comprehended not only as man's final fulfillment of freedom through intuitive knowledge, but also as man's self-cultivation in practice. I maintain that a free man, as Spinoza endeavors to become, is equivalent to a Neo-Confucian sage. (shrink)

There is an ancient puzzle about divine foreknowledge and human freedom. If God has already known that you will do a certain thing tomorrow, then it must already be a settled fact that God has known this. Since knowledge entails truth, it must also be a settled fact that you will do it. In that case, you really cannot avoid doing it. If so, then when you do it tomorrow, you won't do it freely. ;This dissertation consists of a careful (...) statement of the puzzle and an examination of its principal solutions. These are fatalism, the view that nothing about the past, present, or future is open, eternalism, the view that God exists outside of time, semantic indeterminism, the view that some propositions are neither true nor false, and Ockhamism, the view that some things about the past are open. ;In Chapter I the puzzle is stated carefully and its solutions are sketched. Chapters II through V each discuss one of the principal solutions. It is argued that fatalism and semantic indeterminism are not adequate solutions to the puzzle. These positions cannot accommodate or adequately explain away our intuition that there is something someone can but will not do. Eternalism is seen to be a formally coherent view, but it also does not provide a satisfying solution to the puzzle. It is argued that Ockham's solution succeeds where the others fail. Finally, it is argued that although Ockham denies the necessity of the past, endorsing his solution does not force one to hold that we can literally change the past. It is concluded that Ockham's solution accommodates our intuitions about freedom and the future without charging a price. (shrink)
