Newton’s Principia on God-mediated action
As John Henry states, Newton simply wants to reaffirm the truth of God’s omnipresence without directly involving him in the physics of the world system. Newton simply wants to distance himself from a Cartesian concept of God and convince the … Read More

An Epistemic Evolution of Intelligence
The perception of intelligence as power has intensified during the Second World War, when several intelligence agencies has been formalized and significantly increased. In all countries, new agencies and departments have been set up to deal with threats. Government publications … Read More

Paradoxes of causal loops in spacetime
There is, among some scientists and philosophers, the idea that any theory that would allow the time travel would introduce causal issues. These types of temporal paradoxes can be avoided by the Novikov self-consistency principle or by a variation in … Read More

The Ontology of General Relativity
General Relativity generated various early philosophical interpretations. His adherents have highlighted the “relativization of inertia” and the concept of simultaneity, Kantians and Neo-Kantians have underlined the approach of certain synthetic “intellectual forms” (especially the principle of general covariance, and logical … Read More

Space, time, and time travel
Newton supported the idea of absolute time, unlike Leibniz, for which time is only a relation between events and cannot be expressed independently, a statement in concordance with the relativity of space-time. Eternalism claims that the past and the future … Read More

Science and pseudoscience – Falsifiability
The delimitation between science and pseudoscience is part of the more general task of determining which beliefs are epistemologically justified. Standards for demarcation may vary by domain, but several basic principles are universally accepted. Karl Popper proposed falsifiability as an … Read More

Grandfather paradox in time travel
The most well-known example of the impossibility of traveling in time is the grandfather paradox or self-infanticide argument: a person who travels in the past and kills his own grandfather, thus preventing the existence of one of his parents and … Read More

Karl Popper’s demarcation problem
Karl Popper, as a critical rationalist, was an opponent of all forms of skepticism, conventionalism and relativism in science. A major argument of Popper is Hume’s critique of induction, arguing that induction should never be used in science. But he … Read More

Classical theory of singularities
The singularities from the general relativity resulting by solving Einstein’s equations were and still are the subject of many scientific debates: Are there singularities in spacetime, or not? Big Bang was an initial singularity? If singularities exist, what is their … Read More
