The term phenomenon is a foundational term in philosophy, given that it carries many connotations.
The phenomenon has many meanings:
1- The external reality that affects the senses, such as physical and chemical phenomena.
2 – The psychological reality that is perceived through feeling, such as emotional and mental phenomena.
3- The phenomenon is also applied to all the empirical facts that science investigates.
4- For the German philosopher Kant, the phenomenon has a special meaning, which is its launch of everything that happens in time and space.
