Experience

Experience is knowledge of and skill in something gained through being involved in or exposed to it over a period of time. It generally refers to know-how or procedural knowledge, rather than propositional knowledge. Knowledge based on experience is also known as empirical knowledge or a posteriori knowledge. A person with considerable experience in a certain field is called an expert.

If someone is recounting an event they witnessed or took part off they are said to have had a "First hand experience".

Relative and collective experience

Experience is regarded as the prime factor in devoloping one's point of view. Naturally, there are differences between each person with respect to their experiences.

Collectively, differences in experience can exist between generations as in the case of access to education, material resources, prosperity, social interaction, moral development, dealing with conflicts, etc. These collective differences can manifest due to geographic differences as well, where different social environment and opportunity has bears on one's personal ability to share experience with others, and relate. As human societies advance and become hyperconnected, geography plays less and less of a role in defining social and ethnic boundaries, by which people come to a common experience.
