An invention is a unique or novel device, method, composition, process or discovery. It may also be an improvement upon a machine or product, or alternate means of achieving a process. An invention that is not derived from an existing model or idea, or that achieves a completely unique function, discovery, or result, may be a radical breakthrough. If such a work has novel and not obvious to others skilled in the same field, the inventor may be able to obtain the legal protection of a patent.

Another meaning of invention is cultural invention, which is an innovative set of useful social behaviors adopted by people and passed on to others. Invention is also an important component of artistic and design creativity, although the patentability of artistic invention is heavily debated.

Regardless of type, inventions often extend the boundaries of human knowledge, experience or capability.

The idea for an invention may be developed on paper or on a computer, by writing or drawing, by trial and error, by making models, by experimenting, by testing and/or by making the invention in its whole form. Brainstorming also can spark new ideas for an invention. Collaborative creative processes are frequently used by designers, architects and scientists. Co-inventors are frequently named on patents.

Sigmund Freud (German pronunciation: [ˈziːkmʊnt ˈfʁɔʏt]), born Sigismund Schlomo Freud (6 May 1856 – 23 September 1939), was an Austrian neurologist who founded the discipline of psychoanalysis. Freud's family and ancestry were Jewish. Freud always considered himself a Jew even though he rejected Judaism and had a critical view of religion. Freud's parents were poor, but ensured his education. Freud was an outstanding pupil in high school, and graduated the Matura with honors in 1873. Interested in philosophy as a student, Freud later turned away from it and became a neurological researcher into cerebral palsy, Aphasia and microscopic neuroanatomy.

Freud went on to develop theories about the unconscious mind and the mechanism of repression, and established the field of verbal psychotherapy by creating psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient (or "analysand") and a psychoanalyst. Though psychoanalysis has declined as a therapeutic practice, it has helped inspire the development of many other forms of psychotherapy, some diverging from Freud's original ideas and approach. Freud postulated the existence of libido (an energy with which mental process and structures are invested), developed therapeutic techniques such as the use of free association (in which patients report their thoughts without reservation and make no attempt to concentrate while doing so), discovered the transference (the process by which patients displace on to their analysts feelings based on their experience of earlier figures in their lives) and established its central role in the analytic process, and proposed that dreams help to preserve sleep by representing as fulfilled wishes that would otherwise awake the dreamer. He was also a prolific essayist, drawing on psychoanalysis to contribute to the interpretation and critique of culture.
