Experience as a general concept comprises knowledge of or skill of some thing or some event gained through involvement in or exposure to that thing or event. The history of the word experience aligns it closely with the concept of experiment. For example, the word experience could be used in a statement like: "I have experience in fishing".
The concept of experience generally refers to know-how or procedural knowledge, rather than propositional knowledge: on-the-job training rather than book-learning. Philosophers dub knowledge based on experience "empirical knowledge" or "a posteriori knowledge".
The interrogation of experience has a long tradition in continental philosophy. Experience plays an important role in the philosophy of Søren Kierkegaard. The German term Erfahrung, often translated into English as "experience", has a slightly different implication, connoting the coherency of life's experiences.
A person with considerable experience in a specific field can gain a reputation as an expert.
Certain religious traditions (such as types of Buddhism, Surat Shabd Yoga, mysticism and Pentecostalism) and educational paradigms with, for example, the conditioning of military recruit-training (also known as "boot camps"), stress the experiential nature of human epistemology. This stands in contrast to alternatives: traditions of dogma, logic or reasoning. Participants in activities such as tourism, extreme sports and recreational drug-use also tend to stress the importance of experience.
Types of experience 
The word "experience" may refer, somewhat ambiguously, both to mentally unprocessed immediately perceived events as well as to the purported wisdom gained in subsequent reflection on those events or interpretation of them.
Physical experience 
Mental experience 
Mental experience involves the aspect of intellect and consciousness experienced as combinations of thought, perception, memory, emotion, will and imagination, including all unconscious cognitive processes. The term can refer, by implication, to a thought process. Mental experience and its relation to the physical brain form an area of philosophical debate: some identity theorists originally argued that the identity of brain and mental states held only for a few sensations. Most theorists, however, generalized the view to cover all mental experience.
Mathematicians can exemplify cumulative mental experience in the approaches and skills with which they work. Mathematical realism, like realism in general, holds that mathematical entities exist independently of the human mind. Thus humans do not invent mathematics, but rather discover and experience it, and any other intelligent beings in the universe would presumably do the same. This point of view regards only one sort of mathematics as discoverable; it sees triangles, right angles, and curves, for example, as real entities, not just the creations of the human mind. Some working mathematicians have espoused mathematical realism as they see themselves experiencing naturally-occurring objects. Examples include Paul Erdős and Kurt Gödel. Gödel believed in an objective mathematical reality that could be perceived in a manner analogous to sense perception. Certain principles (for example: for any two objects, there is a collection of objects consisting of precisely those two objects) could be directly seen to be true, but some conjectures, like the continuum hypothesis, might prove undecidable just on the basis of such principles. Gödel suggested that quasi-empirical methodology such as experience could provide sufficient evidence to be able to reasonably assume such a conjecture. With experience, there are distinctions depending on what sort of existence one takes mathematical entities to have, and how we know about them.
Emotional experience 
Humans can rationalize falling in (and out) of love as "emotional experience". Societies which lack institutional arranged marriages can call on emotional experience in individuals to influence mate-selection. The concept of emotional experience also appears in the notion of empathy.
Spiritual experience 
Newberg and Newberg provide a view on spiritual experience.
Religious experience 
Mystics can describe their visions as "spiritual experiences". However, psychology and neuropsychology may explain the same experiences in terms of altered states of consciousness, which may come about accidentally through (for example) very high fever, infections such as meningitis, sleep deprivation, fasting, oxygen deprivation, nitrogen narcosis (deep diving), psychosis, temporal-lobe epilepsy, or a traumatic accident. People can likewise achieve such experiences more deliberately through recognized mystical practices such as sensory deprivation or mind-control techniques, hypnosis, meditation, prayer, or mystical disciplines such as mantra meditation, yoga, Sufism, dream yoga, or surat shabda yoga. Some "primitive religions" encourage spiritual experiences through the ingestion of psychoactive drugs such as alcohol and opiates, but more commonly with entheogenic plants and substances such as cannabis, salvia divinorum, psilocybin mushrooms, peyote, DXM, ayahuasca, or datura. Another way to induce spiritual experience through an altered state of consciousness involves psychoacoustics, binaural beats, or light-and-sound stimulation.
Social experience 
Growing up and living within a society can foster the development and observation of social experience. Social experience provides individuals with the skills and habits necessary for participating within their own societies, as a society itself is formed through a plurality of shared experiences forming norms, customs, values, traditions, social roles, symbols and languages.
Virtual experience and simulation gaming 
Using computer simulations can enable a person or groups of persons to have virtual experiences in virtual reality. Role-playing games treat "experience" (and its acquisition) as an important, measurable, and valuable commodity. Many role-playing video games, for instance, feature units of measurement used to quantify or assist a player-character's progression through the game - called experience points or xp.
Immediacy of experience 
Someone able to recount an event they witnessed or took part in has "first hand experience". First hand experience of the "you had to be there" variety can seem especially valuable and privileged, but it often remains potentially subject to errors in sense-perception and in personal interpretation.
Subjective experience 
Subjective experience can involve a state of individual subjectivity, perception on which one builds one's own state of reality; a reality based on one’s interaction with one's environment. The subjective experience depends on one’s individual ability to process data, to store and internalize it. For example: our senses collect data, which we then process according to biological programming (genetics), neurological network-relationships and other variables such as relativity[disambiguation needed] etc.,[clarification needed] all of which affect our individual experience of any given situation in such a way as to render it subjective.

Changes in experience through history 
Some post-modernists suggest that the nature of human experiencing (quite apart from the details of the experienced surrounds) has undergone qualitative change during transition from the pre-modern through the modern to the post-modern.
Alternatives to experience 
- "Nothing, indeed, can be more harmful or more unworthy of the philosopher, than the vulgar appeal to so-called experience. Such experience would never have existed at all, if at the proper time, those institutions had been established in accordance with ideas."
The American author Ralph Waldo Emerson wrote an essay entitled "Experience" (published in 1844), in which he asks readers to disregard emotions that could alienate them from the divine; it provides a somewhat pessimistic representation of the Transcendentalism associated with Emerson.
