An event recognised as responsible for the production of a certain outcome... Human intuition is extremely keen in detecting and ascertaining this type of causation and hence is considered the key to construct explanations... and the ultimate criterion (known as “cause in fact”) for determining legal responsibility.
Clearly, actual causation requires information beyond that of necessity and sufficiency: the actual process mediating between the cause and the effect must enter into consideration.

The means whereby this work of Nature is brought to its consummate issue are forces of Nature working under her Laws by the method of cause and effect. The principle, or "law," of causation is a metaphysical postulate; in the sense that such a fact as causation is unproved and unprovable. No man has ever observed a case of causation, as is a commonplace with the latterday psychologists.

CAUSA (causa) Todo lo que existe se relaciona causalmente, de manera que este vínculo constante permite hablar de «orden y conexión» (E2P7), de leyes naturales, etc., por contraste con lo que sería el caos o la excepción sobrenatural (el milagro). Como ya afirmó la tradición y la ciencia moderna lleva al límite, la inteligibilidad de lo real descansa en el conocimiento de los efectos por las causas (TIE 85, E1Ax4), lo que se resume en el adagio causa sive ratio o dar razón causal de algo. Hay que partir de lo que es causa de sí (Dios) y comprender desde ahí las secuencias productoras (E1Def1, P16, P18, P28) que eliminan la contingencia y la indeterminación (E1P27 y P29). Ahora bien, a menudo no es posible conocer la concatenación causal de la realidad a escala microfísica, lo que abre la puerta a la consideración — en la vida cotidiana — de las cosas «como si» fueran posibles.

The opinion appears to be gaining ground that this very general conception of functionality, born on mathematical ground, is destined to supersede the narrower notion of causation, traditional in connection with the natural sciences. As an abstract formulation of the idea of determination in its most general sense, the notion of functionality includes and transcends the more special notion of causation as a one-sided determination of future phenomena by means of present conditions; it can be used to express the fact of the subsumption under a general law of past, present, and future alike, in a sequence of phenomena. From this point of view the remark of Huxley that Mathematics "knows nothing of causation" could only be taken to express the whole truth, if by the term "causation" is understood "efficient causation." The latter notion has, however, in recent times been to an increasing extent regarded as just as irrelevant in the natural sciences as it is in Mathematics; the idea of thorough-going determinancy, in accordance with formal law, being thought to be alone significant in either domain.

Correlation isn’t causation but neurons that fire together wire together. Thus the confusion.

The postulation of a principle of causality, “to every effect there is a cause,” has been a continuing central problem for philosophy (Popper, 1972). Its role as a source of contention in modern science (Jauch, 1973) is epitomized by Einstein’s remark that, “I can’t believe that God plays dice.” Many of the arguments about the application of the principle are very relevant to systems science and to problems of system identification and machine learning, on the one hand,and to epistemology and behavioural psychology, on the other. In current system science the theory of causal deterministic systems is most well developed and generally applied, while the theory of modeling with alternative structures, e.g., stochastic automata, indeterminate automata, products of asynchronous automata, etc., has not been developed to the same degree.

The belief in causality is metaphysical. It is nothing but a typical metaphysical hypostatization of a well-justified methodological rule- the scientist's decision never to abandon his search for laws. The metaphysical belief in causality seems thus more fertile in its various manifestations than any indeterminist physics metaphysics of the kind advocated by Heisenberg. Indeed, we can see that Heisenberg's comments have had a crippling effect on research. Connections which are not far to seek may easily be overlooked if its continually repeated that the search for any such connections is 'meaningless'.

"We say it is "explanation" but it is only in "description" that we are in advance of the older stages of knowledge and science. We describe better we explain just as little as our predecessors. We have discovered a manifold succession where the naive man and investigator of older cultures saw only two things "cause" and "effect " as it was said we have perfected the conception of becoming but have not got a knowledge of what is above and behind the conception. The series of "causes" stands before us much more complete in every case we conclude that this and that must first precede in order that that other may follow - but we have not grasped anything thereby. The peculiarity for example in every chemical process seems a "miracle " the same as before just like all locomotion nobody has "explained" impulse. How could we ever explain We operate only with things which do not exist with lines surfaces bodies atoms divisible times divisible spaces - how can explanation ever be possible when we first make everything a conception our conception It is sufficient to regard science as the exactest humanizing of things that is possible we always learn to describe ourselves more accurately by describing things and their successions. Cause and effect: there is probably never any such duality in fact there is a continuum before us from which we isolate a few portions - just as we always observe a motion as isolated points and therefore do not properly see it but infer it. The abruptness with which many effects take place leads us into error it is however only an abruptness for us. There is an infinite multitude of processes in that abrupt moment which escape us. An intellect which could see cause and effect as a continuum which could see the flux of events not according to our mode of perception as things arbitrarily separated and broken - would throw aside the conception of cause and effect and would deny all conditionality."

Behold... the only... [rule] we can follow: when a phenomenon appears... as the cause of another, we regard it as anterior. ...[T]herefore by cause... we define time; but...how do we recognize which is the cause and which the effect? We assume... the anterior fact, the antecedent, is the cause of the... consequent. It is then by time that we define cause. ...[S]hall we escape from this vicious circle?

[L]et us consider, with respect to causes, what they are, and how many there are in number... this also must be done by us in discoursing concerning generation and corruption, and all physical mutation... knowing the principles of these...
Cause... is after one manner said to be that, from which, being inherent, something is produced... But after another manner cause is form and paradigm (and this is the definition of the essence of a thing) and the genera of this. ...But it happens... that there are also many causes of the same thing, and this is not from accident. ...seed, a physician, he who consults, and, in short, he who makes, are all of them causes, as that whence the principle of mutation, or permanency, or motion is derived. ...It is, however, necessary always to investigate the supreme cause of every thing ...Further still, it is necessary to investigate the genera of genera; and the particulars of particulars... We should also explore the capacities of the capabilities, and the energizers of the things affected by energy.

The idea that time may be an active factor in causation has the mathematical significance that <nowiki>' </nowiki>t<nowiki> '</nowiki> (for the system in question) must appear explicitly in the formulation of the law. ...Such law may claim to express the fact of historic, irreversible duration.

Although people cannot define existence and do use the term with some looseness, yet it is possible to give an extensive definition by pointing to the sorts of things that everyone believes to exist. It is still easier to point to the sort of entities that people agree in believing not to exist, and happily, this is really what concerns us most. People mean by saying that causation only applies to things that exist that it applies, if at all, to what can change; and they believe that, if anything can change, it is things like chairs and tables and minds, and not those like the propositions of Euclid and the multiplication table. What would be agreed then is that, if causal laws apply to anything it is to what can change in so far as it changes.

The laborious process of causation which sooner or later will bring about every possible effect, including, consequently, those which one believed to be least possible, naturally slow at times, is rendered slower still by our desire (which in seeking to accelerate only obstructs it), by our very existence, and comes to fruition only when we have ceased to desire, and sometimes ceased to live.

The last decade has seen a great deal of research on the perception of causation and the consequences of such perception. Conducted primarily within social psychology, the focus has been the perceived causes of other persons' behavior. A parallel analysis has been made of the perceived causes of one's own behavior, and the liveliest recent topic has concerned differences between other-perception and self-perception. The study of perceived causation is identified by the term "attribution theory," attribution referring to the perception inference of cause. As we will see, there is not one but many attribution "theories" and the term refers to several different kinds of problem. The common ideas are that people interpret behavior in terms of its causes and that these interpretations play an important role in determining reactions to the behavior.
