Scientific method refers to a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry must be based on gathering empirical and measurable evidence subject to specific principles of reasoning. The Oxford English Dictionary says that scientific method is: "a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses."
Although procedures vary from one field of inquiry to another, identifiable features distinguish scientific inquiry from other methods of obtaining knowledge. Scientific researchers propose hypotheses as explanations of phenomena, and design experimental studies to test these hypotheses via predictions which can be derived from them. These steps must be repeatable, to guard against mistake or confusion in any particular experimenter. Theories that encompass wider domains of inquiry may bind many independently derived hypotheses together in a coherent, supportive structure. Theories, in turn, may help form new hypotheses or place groups of hypotheses into context.
Scientific inquiry is generally intended to be as objective as possible, to reduce biased interpretations of results. Another basic expectation is to document, archive and share all data and methodology so they are available for careful scrutiny by other scientists, giving them the opportunity to verify results by attempting to reproduce them. This practice, called full disclosure, also allows statistical measures of the reliability of these data to be established.
Scientific methodology directs that hypotheses be tested in controlled conditions which can be reproduced by others.
A scientific theory comprises a collection of concepts, including abstractions of observable phenomena expressed as quantifiable properties, together with rules (called scientific laws) that express relationships between observations of such concepts. A scientific theory is constructed to conform to available empirical data about such observations, and is put forth as a principle or body of principles for explaining a class of phenomena.[1]
A scientific theory is a type of inductive theory, in that its content (i.e. empirical data) could be expressed within some formal system of logic whose elementary rules (i.e. scientific laws) are taken as axioms. In a deductive theory, any sentence which is a logical consequence of one or more of the axioms is also a sentence of that theory.
In the humanities, one finds theories whose subject matter does not (only) concern empirical data, but rather ideas. Such theories are in the realm of philosophical theories as contrasted with scientific theories. A philosophical theory is not necessarily scientifically testable through experiment.
Cartesian doubt is a systematic process of being skeptical about (or doubting) the truth of one's beliefs, which has become a characteristic method in philosophy. A pioneer of methodic doubt is the Persian philosopher Al-Ghazali. This method of doubt was largely popularized in Western philosophy by René Descartes (1596-1650), who sought to doubt the truth of all his beliefs in order to determine which beliefs he could be certain were true.
Methodological skepticism is distinguished from philosophical skepticism in that methodological skepticism is an approach that subjects all knowledge claims to scrutiny with the goal of sorting out true from false claims, whereas philosophical skepticism is an approach that denies the possibility of knowledge.
Scientific skepticism is the practice of questioning the veracity of claims lacking empirical evidence or reproducibility, as part of a methodological norm pursuing "the extension of certified knowledge". For example, Robert K. Merton asserts that all ideas must be tested and are subject to rigorous, structured community scrutiny.
Philosophical skepticism (from Greek σκέψις - skepsis meaning "enquiry" - UK spelling, scepticism) is both a philosophical school of thought and a method that crosses disciplines and cultures. Many skeptics critically examine the meaning systems of their times, and this examination often results in a position of ambiguity or doubt. This skepticism can range from disbelief in contemporary philosophical solutions, to agnosticism, to rejecting the reality of the external world. One kind of scientific skepticism refers to the critical analysis of claims lacking empirical evidence. We are all skeptical of some things, especially since doubt and opposition are not always clearly distinguished. Philosophical skepticism, however, is an old movement with many variations, and contrasts with the view that at least one thing is certain, but if by being certain we mean absolute or unconditional certainty, then it is doubtful if it is rational to claim to be certain about anything. Indeed, for Hellenistic philosophers claiming that at least one thing is certain makes one a dogmatist.
Philosophical skepticism is distinguished from methodological skepticism in that philosophical skepticism is an approach that denies the possibility of certainty in knowledge, whereas methodological skepticism is an approach that subjects all knowledge claims to scrutiny with the goal of sorting out true from false claims.
Ancient Pyrrhonism. Whereas academic skepticism, with Carneades as its most famous adherent, claims that "Nothing can be known, not even this", Pyrrhonian skeptics withhold any assent with regard to non-evident propositions and remain in a state of perpetual inquiry. They disputed the possibility of attaining truth by sensory apprehension, reason, or the two combined, and thence inferred the need for total suspension of judgment (epoché) on things. According to them, even the statement that nothing can be known is dogmatic. They thus attempted to make their skepticism universal, and to escape the reproach of basing it upon a fresh dogmatism. Mental imperturbability (ataraxia) was the result to be attained by cultivating such a frame of mind. As in Stoicism and Epicureanism, the happiness or satisfaction of the individual was the goal of life, and all three philosophies placed it in tranquility or indifference. According to the Pyrrhonists, it is our opinions or unwarranted judgments about things which turn them into desires, painful effort, and disappointment. From all this a person is delivered who abstains from judging one state to be preferable to another. But, as complete inactivity would have been synonymous with death, the skeptic, while retaining his consciousness of the complete uncertainty enveloping every step, might follow custom (or nature) in the ordinary affairs of life.
Academic skepticism refers to the skeptical period of ancient Platonism dating from around 266 BC, when Arcesilaus became head of the Platonic Academy, until around 90 BC, when Antiochus of Ascalon rejected skepticism. Like their fellow Pyrrhonists, they maintained that knowledge of things is impossible. Ideas or notions are never true; nevertheless, there are degrees of probability, and hence degrees of belief, which allow one to act. The school was characterized by its attacks on the Stoics and on their belief in convincing impressions which lead to true knowledge. The most important Academic skeptics were Arcesilaus, Carneades, and Philo of Larissa.
The term parapsychology was coined in or around 1889 by philosopher Max Dessoir, and originates from para meaning "alongside", and psychology. The term was adopted by J.B. Rhine in the 1930s as a replacement for the term psychical research. Parapsychologists study a number of ostensible paranormal phenomena, including telepathy, precognition, clairvoyance, psychokinesis, near-death experiences, reincarnation and apparitional experiences.
Parapsychology research is conducted in some 30 different countries. Laboratory and field research is conducted through private institutions and universities. Privately-funded units in psychology departments at universities in the United Kingdom are among the most active today. In the United States, interest in research peaked in the 1970s and university-based research has declined since then, although private institutions still receive funding from donations. While parapsychological research has occasionally appeared in mainstream academic journals, most of the recent research is published in a small number of niche journals. Journals dealing with parapsychology include the Journal of Parapsychology, Journal of Near-Death Studies, Journal of Consciousness Studies, Journal of the Society for Psychical Research and Journal of Scientific Exploration.
Pseudoscience is a claim, belief, or practice which is presented as scientific, but which does not adhere to a valid scientific method, lacks supporting evidence or plausibility, cannot be reliably tested, or otherwise lacks scientific status. Pseudoscience is often characterized by the use of vague, exaggerated or unprovable claims, an over-reliance on confirmation rather than rigorous attempts at refutation, a lack of openness to evaluation by other experts, and a general absence of systematic processes to rationally develop theories.
Paranormal is a general term (coined ca. 1915–1920) that designates experiences that lie outside "the range of normal experience or scientific explanation" or that indicates phenomena understood to be outside of science's current ability to explain or measure. Paranormal phenomena are distinct from certain hypothetical entities, such as dark matter and dark energy, only insofar as paranormal phenomena are inconsistent with the world as already understood through empirical observation coupled with scientific methodology.
Thousands of stories relating to paranormal phenomena are found in popular culture, folklore, and the recollections of individual subjects. In contrast, the scientific community, as referenced in statements made by organizations such as the United States National Science Foundation, maintains that scientific evidence does not support a variety of beliefs that have been characterized as paranormal.
“Paranormal” has been in the English language since at least 1920. It consists of two parts: para and normal. In most definitions of the word paranormal, it is described as anything that is beyond or contrary to what is deemed scientifically possible. The definition implies that the scientific explanation of the world around us is the 'normal' part of the word and 'para' makes up the above, beyond, beside, contrary, or against part of the meaning.
Para has a Greek and Latin origin. Its most common meaning (the Greek usage) is 'similar to' or 'near to', as in paragraph. In Latin, para means 'above,' 'against,' 'counter,' 'outside,' or 'beyond'. For example, parapluie in French means 'counter-rain' – an umbrella. It can be construed, then, that the term paranormal is derived from the Latin use of the prefix 'para', meaning 'against, counter, outside or beyond the norm.'
Notable paranormal beliefs include those that pertain to ghosts, extraterrestrial life and unidentified flying objects, and cryptids.
The supernatural or supranatural (Latin: super, supra "above" + natura "nature") is that which is not subject to the laws of nature, or more figuratively, that which is said to exist above and beyond nature. With neoplatonic and medieval scholastic origins, the metaphysical considerations can be difficult to approach as an exercise in philosophy or theology because any dependencies on its antithesis, the natural, will ultimately have to be inverted or rejected. In popular culture and fiction, the supernatural is whimsically associated with the paranormal and the occult, this differs from traditional concepts in some religions, such as Catholicism, where divine miracles are considered supernatural.
Ghost, In traditional belief and fiction, a ghost is the soul or spirit of a deceased person or animal that can appear, in visible form or other manifestation, to the living. Descriptions of the apparition of ghosts vary widely from an invisible presence to translucent or barely visible wispy shapes, to realistic, life-like visions. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a séance.
The belief in manifestations of the spirits of the dead is widespread, dating back to animism or ancestor worship in pre-literate cultures. Certain religious practices—funeral rites, exorcisms, and some practices of spiritualism and ritual magic—are specifically designed to appease the spirits of the dead. Ghosts are generally described as solitary essences that haunt particular locations, objects, or people they were associated with in life, though stories of the phantom armies, ghost trains, phantom ships, and even ghost animals have also been recounted.
