Idola specus (singular Idolum specus), normally translated as "Idols of the Cave" (or "Idols of the Den"), is a type of logical fallacy whereby the peculiar biases of individuals lead them to errors. This Latin term was coined by Sir Francis Bacon and used in his Novum Organum , one of the earliest treatises arguing the case for the logic and method of modern science. He described them as deriving from "the peculiar constitution, mental or bodily, of each individual; and also in education, habit, and accident". [1]
The idola specus are prejudices, by which individuals inappropriately extend norms or tenets that derive his or her own culture and social group, or to his or her own preferences. Racism, sexism and, more generally just "biases" are examples of idola specus, but the concept goes beyond them to the criticism of all forms of irreflexive subjectivity or individual predisposition.
The term is one of four such "idols" which represent "idols and false notions which are now in possession of the human understanding, and have taken deep root therein, not only so beset men's minds that truth can hardly find entrance, but even after entrance is obtained, they will again in the very instauration of the sciences meet and trouble us, unless men being forewarned of the danger fortify themselves as far as may be against their assaults". [2]
Besides idola specus, there are also idola tribus (Idols of the Tribe, caused by human nature), idola fori , (Idols of the Market Place, caused by language) and idola theatri (Idols of the Theatre, which are caused by the influence of philosophers).
The Idols of the Cave are the idols of the individual man. For everyone (besides the errors common to human nature in general) has a cave or den of his own, which refracts and discolors the light of nature, owing either to his own proper and peculiar nature; or to his education and conversation with others; or to the reading of books, and the authority of those whom he esteems and admires; or to the differences of impressions, accordingly as they take place in a mind preoccupied and predisposed or in a mind indifferent and settled; or the like. So that the spirit of man (according as it is meted out to different individuals) is in fact a thing variable and full of perturbation, and governed as it were by chance. Whence it was well observed by Heraclitus that men look for sciences in their own lesser worlds, and not in the greater or common world.

In more detail, Bacon said that there are a "great number and variety" of idols of the cave but he chooses to select examples which give "the most important caution", and which "have most effect in disturbing the clearness of the understanding". [1] He judged that they "grow for the most part either out of the predominance of a favorite subject, or out of an excessive tendency to compare or to distinguish, or out of partiality for particular ages, or out of the largeness or minuteness of the objects contemplated." [3] Concerning these most important variants he wrote in more detail:
Bacon also drew general advice for more methodical future study of nature, aimed at avoiding the idols of the cave: "generally let every student of nature take this as a rule: that whatever his mind seizes and dwells upon with peculiar satisfaction is to be held in suspicion, and that so much the more care is to be taken in dealing with such questions to keep the understanding even and clear."

Francis Bacon, 1st Viscount St Alban, also known as Lord Verulam, was an English philosopher and statesman who served as Attorney General and Lord Chancellor of England under King James I. Bacon led the advancement of both natural philosophy and the scientific method and his works remained influential even in the late stages of the Scientific Revolution.
The Baconian method is the investigative method developed by Sir Francis Bacon, one of the founders of modern science, and thus a first formulation of a modern scientific method. The method was put forward in Bacon's book Novum Organum (1620), or 'New Method', and was supposed to replace the methods put forward in Aristotle's Organon. This method was influential upon the development of the scientific method in modern science; but also more generally in the early modern rejection of medieval Aristotelianism.
William Gilbert, also known as Gilberd, was an English physician, physicist and natural philosopher. He passionately rejected both the prevailing Aristotelian philosophy and the Scholastic method of university teaching. He is remembered today largely for his book De Magnete (1600).
The Novum Organum, fully Novum Organum, sive Indicia Vera de Interpretatione Naturae or Instaurationis Magnae, Pars II, is a philosophical work by Francis Bacon, written in Latin and published in 1620. The title is a reference to Aristotle's work Organon, which was his treatise on logic and syllogism. In Novum Organum, Bacon details a new system of logic he believes to be superior to the old ways of syllogism. This is now known as the Baconian method.
New Atlantis is an incomplete utopian novel by Sir Francis Bacon, published posthumously in 1626. It appeared unheralded and tucked into the back of a longer work of natural history, Sylva Sylvarum. In New Atlantis, Bacon portrayed a vision of the future of human discovery and knowledge, expressing his aspirations and ideals for humankind. The novel depicts the creation of a utopian land where "generosity and enlightenment, dignity and splendour, piety and public spirit" are the commonly held qualities of the inhabitants of the mythical Bensalem. The plan and organisation of his ideal college, Salomon's House, envisioned the modern research university in both applied and pure sciences.
"An Experimental Enquiry Concerning the Source of the Heat which is Excited by Friction" is a scientific paper by Benjamin Thompson, Count Rumford, which was published in the Philosophical Transactions of the Royal Society in 1798. The paper provided a substantial challenge to established theories of heat, and began the 19th century revolution in thermodynamics.
An Instance of the Fingerpost is a 1997 historical mystery novel by Iain Pears.
The phrase "scientia potentia est" is a Latin aphorism meaning "knowledge is power", commonly attributed to Sir Francis Bacon. The expression "ipsa scientia potestas est" occurs in Bacon's Meditationes Sacrae (1597). The exact phrase "scientia potentia est" was written for the first time in the 1668 version of Leviathan by Thomas Hobbes, who was a secretary to Bacon as a young man.
The history of scientific method considers changes in the methodology of scientific inquiry, as distinct from the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of one or another approach to establishing scientific knowledge.
Nous, or Greek νοῦς, sometimes equated to intellect or intelligence, is a concept from classical philosophy for the faculty of the human mind necessary for understanding what is true or real.
Nature has two inter-related meanings in philosophy and natural philosophy. On the one hand, it means the set of all things which are natural, or subject to the normal working of the laws of nature. On the other hand, it means the essential properties and causes of individual things.
Common sense is sound, practical judgment concerning everyday matters, or a basic ability to perceive, understand, and judge in a manner that is shared by nearly all people.
Idola tribus is a category of logical fallacy, normally translated as "Idols of the Tribe", which refers to a tendency of human nature to prefer certain types of incorrect conclusions. It is a Latin term, coined by Sir Francis Bacon and used in his Novum Organum, one of the earliest treatises arguing the case for the methodical approach of modern science.
Idola fori, sometimes translated as "Idols of the Market Place" or "Idols of the Forum", are a category of logical fallacy which results from the imperfect correspondences between the word definitions in human languages, and the real things in nature which these words represent. The term was coined in Latin by Sir Francis Bacon and used in his Novum Organum, one of the earliest treatises arguing the case for the logic and method of modern science.
Idola theatri is a type of tendency towards logical fallacy or error, normally translated as "idols of the theatre". The Latin was coined by Sir Francis Bacon in his Novum Organum—one of the earliest treatises arguing the case for the logic and method of modern science. Bacon described them as "Idols which have immigrated into men's minds from the various dogmas of philosophies, and also from wrong laws of demonstration." He named them Idols of the Theater "because in my judgment all the received systems are but so many stage plays, representing worlds of their own creation after an unreal and scenic fashion."
Francis Bacon, 1st Viscount St Alban, KC was an English philosopher, statesman, scientist, lawyer, jurist, author, and pioneer of the scientific method. He served both as Attorney General and Lord Chancellor of England. Although his political career ended in disgrace, he remained extremely influential through his works, especially as philosophical advocate and practitioner of the scientific method during the scientific revolution.
The Romantics, in seeking to understand nature in her living essence, studied the 'father of science', Sir Francis Bacon. The view of Bacon and the 'inductive method' that emerges is quite a different one from that tended to prevail both before and then after, here mainly due to John Stuart Mill's interpretation later in the 1800s. For the Romantics, induction as generally interpreted 'was not enough to produce correct understanding in Bacon's terms.' They saw another side of Bacon, generally not developed, one in which nature was a labyrinth not open to "excellence of wit" nor "chance experiments": "Our steps must be guided by a clue, and see what way from the first perception of the sense must be laid out upon a sure plan."
Romantic epistemology emerged from the Romantic challenge to both the static, materialist views of the Enlightenment (Hobbes) and the contrary idealist stream (Hume) when it came to studying life. Romanticism needed to develop a new theory of knowledge that went beyond the method of inertial science, derived from the study of inert nature, to encompass vital nature. Samuel Taylor Coleridge was at the core of the development of the new approach, both in terms of art and the 'science of knowledge' itself (epistemology). Coleridge's ideas regarding the philosophy of science involved Romantic science in general, but Romantic medicine in particular, as it was essentially a philosophy of the science(s) of life.
Unconscious inference, also referred to as unconscious conclusion, is a term of perceptual psychology coined in 1867 by the German physicist and polymath Hermann von Helmholtz to describe an involuntary, pre-rational and reflex-like mechanism which is part of the formation of visual impressions. While precursory notions have been identified in the writings of Thomas Hobbes, Robert Hooke, and Francis North as well as in Francis Bacon's Novum Organum, Helmholtz's theory was long ignored or even dismissed by philosophy and psychology. It has since received new attention from modern research, and the work of recent scholars has approached Helmholtz's view.
The Four Great Errors are four mistakes of human reason regarding causal relationships that the German philosopher Friedrich Nietzsche argues are the basis of all moral and religious propositions. Set forth in his book Twilight of the Idols, first published in 1889, these errors are key in implementing his program of the "revaluation of all values." Nietzsche wanted to liberate people from traditional moral and religious systems by denying the concept of "human accountability," which, he argues, is nothing more than an invention of theologians who wanted to exert power over other people. Unlike most religions and moral systems which hold that virtuous behavior results in happiness, Nietzsche argued the opposite. For Nietzsche, Internal psychological states that we cannot consciously control such as "happiness" are actually the true causes of virtuous behavior, not the human will.
