Subjective Logic - Subjective Opinions

Subjective Opinions

Subjective opinions express subjective beliefs about the truth of propositions with degrees of uncertainty, and can indicate subjective belief ownership whenever required. An opinion is usually denoted as where is the subject, also called the belief owner, and is the proposition to which the opinion applies. An alternative notation is . The proposition is assumed to belong to a frame of discernment (also called state space) e.g. denoted as, but the frame is usually not included in the opinion notation. The propositions of a frame are normally assumed to be exhaustive and mutually disjoint, and subjects are assumed to have a common semantic interpretation of propositions. The subject, the proposition and its frame are attributes of an opinion. Indication of subjective belief ownership is normally omitted whenever irrelevant.

Famous quotes containing the words subjective and/or opinions:

    ... the subjective viewpoint is the only one to use regarding a library. Your true library is a collection of the books you want. You may have deplorably poor taste or bad judgment. Never mind. Correct those traits before you exchange your books.
    Carolyn Wells (1862–1942)

    Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.
    Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
