  • What is Holism?

    A Wikipedia definition is:

    Holism (from ὅλος holos, a Greek word meaning all, entire, total) is the idea that all the properties of a given system (biological, chemical, social, economic, mental, linguistic, etc.) cannot be determined or explained by its component parts alone. Instead, the system as a whole determines in an important way how the parts behave.
    In other words, Holism is a property of any System. But what is Systems? Wikipedia says: System is a set of interacting or interdependent entities, real or abstract, forming an integrated whole.
    Then, Holism could be used as an approach to understand the reality or abstraction. No?. Yes!.

  • The Principle of Psychological acceptability

    Jerome Saltzer and Michael Schroeder in “The Protection of Information in Computer Systems” :

    “[…] Psychological acceptability : It is essential that the human interface be designed for ease of use, so that users routinely and automatically apply the protection mechanisms correctly. Also, to the extent that the user’s mental image of his protection goals matches the mechanisms he must use, mistakes will be minimized. If he must translate his image of his protection needs into a radically different specification language, he will make errors. [..]” Any question?
