    Part of a larger discussion

    Challenges→Strong rationality is a more demanding condition than weak rationality.

    If the epistemic conditions sufficient for weak rationality already entail common knowledge, the additional eliminations attributed to strong rationality are already implicit in weak rationality's closure conditions.

    Key Terms

    Closure conditions(as used in epistemology and logic)
    Rules that describe what conclusions or beliefs you're logically committed to once you accept certain starting beliefs—basically, what follows automatically from what you already believe.
    Entail(In logical reasoning and argumentation)
    To logically follow or guarantee as a necessary consequence; if something is true, what does it force to also be true?
    Implicit(describing how the categorial structure operates in perception)
    Present or involved in something, but not directly stated or obvious—working in the background without being explicitly acknowledged.
    Strong rationality(as a prerequisite assumption in game theory)
    The assumption that every player is perfectly rational and everyone knows that everyone else is also perfectly rational.

    Sufficient conditions(used to explain what makes an event happen)
    A set of circumstances that guarantee something will happen—if all these conditions are present, the outcome must occur.
    Weak rationality(as used in decision theory and epistemology)
    A basic standard for making decisions or beliefs that requires you to be logically consistent and avoid obvious contradictions.
    common knowledge(Condition for the formation of a joint commitment)
    A state in which each party knows the relevant fact, knows that the others know it, and so on — used here as the threshold condition for a joint commitment coming into force.
    epistemic conditions
    Conditions such as space and time, without which we cannot cognize any object
    knowledge(Distinguished from mere true belief, which may be the product of indoctrination and need not exercise deliberative capacities.)
    Justified true belief — true belief that has been arrived at through the exercise of deliberative capacities, including comparison of and deliberation among alternatives.
