Causal Theories of Reference for Proper Names

By: by Nicolae Sfetcu

Presentation and comparison of the main causal theories of reference for proper names, and a proposal of a new approach based on the analogy of the causal chain of reference with the block chain from blockchain technology and Paul Ricœur's narrative theory. After a brief Introduction in which the types of sentences from the concept of possible worlds are reviewed, and an overview of the theory in the Causal Theory of Reference, I present the causal theory of the referenc...

Les singularités comme limites ontologiques de la relativité générale

Voyager dans le temps implique de voyager dans un temps différent du présent, du passé ou du futur, essentiellement sans déplacement dans l'espace par rapport à un système de coordonnées local. Le voyage dans le temps peut être effectué par un corps matériel qui peut être ou non un être vivant, et pour lequel un dispositif spécial appelé machine à voyager dans le temps est utilisé habituellement. Le voyage dans le temps est un concept reconnu en philosophie et en scienc...

Teorii cauzale ale referinței pentru nume proprii

Evidențierea și compararea principalelor teorii cauzale ale referinței pentru nume proprii, și propunerea unei noi abordări pe baza analogiei lanțului cauzal al referinței cu lanțul de blocuri din tehnologia blockchain și teoria narativă a lui Paul Ricœur. După o scurtă Introducere în care trec în revistă tipurile de propoziții din conceptul de lumi posibile, și o prezentare generală a teoriei în Teoria cauzală a referinței, prezint teoria cauzală inițială a referinței p...

John Stuart Mill a susținut că numele pot fi împărțite în două tipuri: conotative și non-conotative. Numele proprii sunt singurele nume de obiecte care nu sunt conotative și nu au, în mod strict, nicio semnificație. (Mill 1882) John Searle susține că fiecare nume propriu este asociat cu un set de descrieri care determină referința. Astfel, numele denotează indirect. (John R. Searle 1958) Saul Kripke critică viziunea fregeană susținută de Searle, argumentând că numele ...

Etica Big Data în Cercetare

By: by Nicolae Sfetcu

Principalele probleme cu care se confruntă oamenii de știință în lucrul cu seturile mari de date (Big Data), evidențiind principale aspecte etice, luând în considerare inclusiv legislația din Uniunea Europeană. După o scurtă Introducere despre Big Data, secțiunea Tehnologia prezintă aplicațiile specifice în cercetare.

Termenul Big Data se referă la extragerea, manipularea și analiza unor seturi de date care sunt prea mari pentru a fi tratate în mod obișnuit. Din această cauză se utilizează software special și, în multe cazuri, și calculatoare și echipamente hardware special dedicate. În general la aceste date analiza se face statistic. Pe baza analizei datelor respective se fac de obicei predicții ale unor grupuri de persoane sau alte entități, pe baza comportamentului acestora în div...

Epistemologia gravitației experimentale – Raționalitatea științifică

Evolution and Ethics of Eugenics

By: by Nicolae Sfetcu

As eugenics is defined, it is very difficult to make a clear distinction between science (medicine, genetic engineering) and eugenics as a included field. And to set a line over which genetic engineering should not go further, according to moral, legal and religious norms. If we accept the help of genetics in finding ways to fight cancer, diabetes, or HIV, we also accept positive eugenics as they are defined now. And if we accept genetic screening, and interventions on t...

Isaac Newton vs. Robert Hooke on the law of universal gravitation

Despite the criticism of Karl Popper's falsifiability theory for the demarcation between science and non-science, mainly pseudo-science, this criterion is still very useful, and perfectly valid after it was perfected by Popper and his followers. Moreover, even in his original version, considered by Lakatos as "dogmatic", Popper did not assert that this methodology is an absolute demarcation criterion: a single counter-example is not enough to falsify a theory; a theory c...

Epistemology of Intelligence Agencies

By: by Nicolae Sfetcu

About the analogy between the epistemological and methodological aspects of the activity of intelligence agencies and some scientific disciplines, advocating for a more scientific approach to the process of collecting and analyzing information within the intelligence cycle. I assert that the theoretical, ontological and epistemological aspects of the activity of many intelligence agencies are underestimated, leading to incomplete understanding of current phenomena and co...

Information is power. This perception 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. Governments are currently spending huge amounts for the intelligence agencies that are considered a major component of national security systems. The intelligence agencies are primarily responsible for identifying and prev...

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...

Causal Loops in Time Travel

By: by Nicolae Sfetcu

About 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 ...

Time travel involves traveling in a time different from the present, in the past or in the future, basically without a space move with reference to a local coordinate system. Time travel can be made by a material body that may or may not be a living being, and for which a special device called the time machine is usually used. Time travel is a recognized concept in philosophy and science, but whose scope is highly disputed, giving rise to numerous paradoxes in both phil...

Andrei Tarkovski (1932 - 1986) s-a născut în Rusia. Tarkovsky a regizat primele cinci din cele șapte filme ale sale (Copilăria lui Ivan (1962), Andrei Rublev (1966), Solaris (1972), Oglinda (1975) și Călăuza (1979)) în Uniunea Sovietică; ultimele sale filme, Nostalgia (1983) și Sacrificiul (1986), au fost produse în Italia și Suedia.

Una din cele mai disputate controverse privind prioritatea unor descoperiri științifice este cea privind legea gravitației universale, între Isaac Newton și Robert Hooke. În acest eseu extind o lucrare mai veche pe aceeași temă, ”Isaac Newton vs. Robert Hooke în legea gravitației universale”. Hooke l-a acuzat pe Newton de plagiat, preluându-i ideile exprimate în lucrările anterioare. În această lucrare încerc să arăt, pe baza unor analize anterioare, că ambii oameni de ș...

Imre Lakatos (1922–1974) a fost unul dintre filozofii moderni ai științei și matematicii. Principala sa contribuție în filosofie a fost dezvoltarea conceptului de metodologie a programelor de cercetare științifică și utilizarea acestei metodologie în reconstrucția rațională a științei. Lakatos își prezintă metodologia în contrast cu sistemele propuse de Popper, Kuhn și Feyerabend, deși de la fiecare a preluat din idei, acceptând un falsificaționism modificat și ideea de ...
