About God in Newton’s correspondence with Richard Bentley and Queries in Opticks

solar systemIn Newton’s correspondence with Richard Bentley, Newton rejected the possibility of remote action, even though he accepted it in the Principia. Practically, Newton’s natural philosophy is indissolubly linked to his conception of God. The knowledge of God seems to be essentially immutable, unlike the laws of nature that can be subjected to refining, revision and rejection procedures. As Newton later states in Opticks, the cause of gravity is an active principle in matter, but this active principle is not an essential aspect of matter, but something that must have been added to matter by God, arguing in the same Query of Opticks even the need for divine intervention.

Isaac Newton on the action at a distance in gravity: With or without God?

Isaac Newton on the action at a distance in gravity: With or without God?The interpretation of Isaac Newton’s texts has sparked controversy to this day. One of the most heated debates relates to the action between two bodies distant from each other (the gravitational attraction), and to what extent Newton involved God in this case. Practically, most of the papers discuss four types of gravitational attractions in the case of remote bodies: direct distance action as intrinsic property of bodies in epicurean sense; direct remote action divinely mediated by God; remote action mediated by a material ether; or remote action mediated by an immaterial ether. The purpose of this paper is to argue that Newton categorically rejected the types of direct action as the intrinsic property of bodies, and remote action mediated by a material ether. Concerning the other two types of action, direct through divine intervention and mediated through an immaterial environment, Newton has repeatedly stated that he does not know the exact cause of gravity, but in both cases, he has directly involved God, directly in the first case and as the primary cause (the environment/ether being the secondary cause) in immaterial mediated action. But since recognition of direct distance action could have given some credit to those who thought gravity could be essential to matter, and hence to atheism, Newton never openly acknowledged the possibility of such an idea.

Causal Loops in Time Travel

Causal Loops in Time TravelAbout the possibility of time traveling based on several specialized works, including those of Nicholas J. J. Smith (“Time Travel“), William Grey (”Troubles with Time Travel”), Ulrich Meyer (”Explaining causal loops”), Simon Keller and Michael Nelson (”Presentists should believe in time-travel”), Frank Arntzenius and Tim Maudlin (“Time Travel and Modern Physics“), and David Lewis (“The Paradoxes of Time Travel”). The article begins with an Introduction in which I make a short presentation of the time travel, and continues with a History of the concept of time travel, main physical aspects of time travel, including backward time travel in the past in general relativity and quantum physics, and time travel in the future, then a presentation of the Grandfather paradox that is approached in almost all specialized works, followed by a section dedicated to the Philosophy of time travel, and a section in which I analyze Causal loops for time travel. I finish my work with Conclusions, in which I sustain my personal opinions on the time travel, and the Bibliography on which the work is based.

The new (liberal) eugenics

Despite the Nazi horrors, in 1953 the new eugenics was founded, when Watson and Crick postulated the double helix of DNA as the basis of chemical heredity. In 1961, scientists have deciphered the genetic code of DNA, laying the groundwork for code manipulation and the potential building of new life forms. After thirty years from the discovery of the DNA structure, the experimenters began to carry out the first clinical studies of human somatic cell therapy.
The practice of prenatal genetic tests identifies genes or unwanted genetic markers. Parents can choose to continue pregnancy or give up the fetus. Once the preimplantation genetic diagnosis occurs, potential parents can choose to use in vitro fertilization and then test early embryonic cells to identify embryos with genes they prefer or avoid. Because of concerns about eugenics, genetic counseling is based on a “non-directive” policy to ensure respect for reproductive autonomy. The argument for this counseling service is that we should balance parental autonomy with child’s autonomy in the future. Specialists have not yet given a clear answer to the question of whether these practices should be considered eugenic practices, or if they are moral practices.

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 atheists that God is a real presence extended in the world. God must exist in space for the space to exist, but God does not only act through contact. Henry believes that Andrew Janiak and Hylarie Kochiras give us a wrong picture of a Newton who believes in opportunism. Newton, Henry asserts, has always assumed that God acted through secondary causes:
