„When a user uses the system, she or he will perform a behaviorally related sequence of transactions in a dialogue with the system. We call such a special sequence a use case.“

—  Ivar Jacobson, p. 127; as cited in: Journal of Object-oriented Programming Vol 10, Nr 2-9. p. 32.

„However useful it is for pedagogical purposes, the biological metaphor of style as a sequence of life-stages was historically misleading, for it bestowed upon the flux of events the shapes and behavior of organisms.“

„Individual societies begin in harmonious adaptation to the environment and, like individuals, quickly get trapped into nonadaptive, artificial, repetitive sequences.
When the individual's behavior and consciousness get hooked to a routine sequence of external actions, he is a dead robot, and it is time for him to die and be reborn. Time to "drop out," "turn on," and "tune in."“

—  Timothy Leary American psychologist 1920 - 1996
Context: Individual societies begin in harmonious adaptation to the environment and, like individuals, quickly get trapped into nonadaptive, artificial, repetitive sequences. When the individual's behavior and consciousness get hooked to a routine sequence of external actions, he is a dead robot, and it is time for him to die and be reborn. Time to "drop out," "turn on," and "tune in." This period of robotization is called the Kali Yuga, the Age of Strife and Empire... The Purpose of Life is Religious Discovery

„Conventional "requirements" …are systems of prescriptions and proscriptions intended solely to limit the physical and intellectual movements of students — to "keep them in line, in sequence, in order," etc.“

—  Neil Postman American writer and academic 1931 - 2003
Context: Conventional "requirements" …are systems of prescriptions and proscriptions intended solely to limit the physical and intellectual movements of students — to "keep them in line, in sequence, in order," etc. They shift focus of attention from the learner (check [Goodwin] Watson again) to the "course." In the process, "requirements" violate virtually everything we know about learning because they comprise the matrix of an elaborate system of punishment, that in turn, comprise a threatening atmosphere in which positive learning cannot occur. The "requirements," indeed, force the teacher — and administrator — into the role of an authoritarian functionary whose primary task becomes that of enforcing the requirements rather than helping the learner to learn. The whole authority of the system is contingent upon the "requirements."

„I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.“

—  Richard Stallman American software freedom activist, short story writer and computer programmer, founder of the GNU project 1953
