title: [Vigilance--a state of order or a force that produces order?].
abstract: The variety of meanings nowadays attached to the notion of "vigilance" essentially mask H. Head's original intentions when he introduced the term more than half a century ago. In an attempt to overcome the obviously existing disturbance in scientific communication, we contrast the new meanings, both with each other and with Head's original conception. We also discuss the importance of "vigilance" as a precursor of a current change of paradigms. We conclude that the original intention of "vigilance" is in line with recently elaborated proposals stressing the self-referential character of living systems. This revised notion of "vigilance" might serve as a conceptual base for empirical research taking self-reference into consideration, and hence for biological research in the true sense of the word.
