The formal sciences are the branches of knowledge that are concerned with formal systems, such as logic, mathematics, theoretical computer science, information theory, systems theory, decision theory, statistics, and some aspects of linguistics.
Unlike other sciences, the formal sciences are not concerned with the validity of theories based on observations in the real world (empirical knowledge), but rather with the properties of formal systems based on definitions and rules. Methods of the formal sciences are, however, essential to the construction and testing of scientific models dealing with observable reality, and major advances in formal sciences have often enabled major advances in the empirical sciences.

Famous quotes containing the words formal and/or sciences:
“That anger can be expressed through words and non-destructive activities; that promises are intended to be kept; that cleanliness and good eating habits are aspects of self-esteem; that compassion is an attribute to be prized—all these lessons are ones children can learn far more readily through the living example of their parents than they ever can through formal instruction.”
—Fred Rogers (20th century)
“I am not able to instruct you. I can only tell that I have chosen wrong. I have passed my time in study without experience; in the attainment of sciences which can, for the most part, be but remotely useful to mankind. I have purchased knowledge at the expense of all the common comforts of life: I have missed the endearing elegance of female friendship, and the happy commerce of domestic tenderness.”
—Samuel Johnson (1709–1784)
