Simplicity is the state or quality of being simple. It usually relates to the burden which a thing puts on someone trying to explain or understand it. Something which is easy to understand or explain is simple, in contrast to something complicated. Alternatively, as Herbert A. Simon suggested, something is simple or complex depending on the way we choose to describe it...^[1] In some uses, simplicity can be used to imply beauty, purity, or clarity. Simplicity may also be used in a negative connotation to denote a deficit or insufficiency of nuance or complexity of a thing, relative to what is supposed to be required.

The concept of simplicity has been related to in the field of epistemology. According to Occam's razor, all other things being equal, the simplest theory is the most likely to be true. In the context of human lifestyle, simplicity can denote freedom from hardship, effort or confusion. Specifically, it can refer to a simple living style.

Simplicity is a theme in the Christian religion. According to St. Thomas Aquinas, God is infinitely simple. The Roman Catholic and Anglican religious orders of Franciscans also strive after simplicity. Members of the Religious Society of Friends (Quakers) practice the Testimony of Simplicity, which is the simplifying of one's life in order to focus on things that are most important and disregard or avoid things that are least important.

In the philosophy of science, simplicity is a meta-scientific criterion by which to evaluate competing theories. In this field, a distinction is often made between two senses of simplicity: syntactic simplicity (the number and complexity of hypotheses), and ontological simplicity (the number and complexity of things postulated). These two aspects of simplicity are often referred to as elegance and parsimony respectively.^[2]

Quotes about simplicity

"Simplicity boils down to two steps: Identify the essential. Eliminate the rest." – Leo Babauta^[3]
"If you can't explain it to a six year old, you don't understand it yourself." – Albert Einstein^[4]
"Simplicity is the ultimate sophistication." – Leonardo da Vinci^{[citation needed]} (Leonardo never wrote nor was reported to have said this.)
"It is true intelligence for a man to take a subject that is mysterious and great in itself and to unfold and simplify it so that a child can understand it." – John H. Taylor
"The Power of Simplicity" – Ken Segall
"The greatest ideas are the simplest." – William Golding^[5]
"Simplicity is a competitive advantage." {Hubspot Company values}

"Simplicity [is] the art of maximizing the amount of work not done" - Agile Manifesto^[7]
