The two men's work was complementary: Lazarsfeld combined quantitative and qualitative research methodologies, along with his logic of concept clarification, and thereby influenced Merton's orientation to historical studies.
How Can the Logic of Color Concepts Apply to Afterimage Colors?
We need theories that are testable, confirmable and refutable based on reliable data, as well as clear and rational argumentation, so the logic of the concepts involved can be followed by policymakers and the public.
According to the classical interpretation, these two arguments (i.e. the liberty arguments) are principally concerned with the logic of our concepts of moral freedom and responsibility.
Yet such options embarrass if the aim was to derive a precise ethical theory from the very logic of the concepts.
A decade before Mehlberg (1958) first proposed what was, in effect, a supervaluationist treatment of vagueness, a student of Łukasiewicz, Stanisław Jaśkowski, published an account of a logic which he proposed as a logic of vague concepts.
He describes his aim as one of "establishing a logic of color concepts", an activity which he describes elsewhere as "laying bare its grammar" (Wittgenstein 1977, para 188, p 43e).
According to the classical account, Hume's effort to articulate the conditions of moral responsibility, and the way they relate to the free will problem, should be understood primarily in terms of his views about the logic of our concepts of "liberty" and "necessity".
Wittgenstein, for example, thought it was central to our having the concepts of color that we do, but as we saw above, he says that "we do not want to find a theory of color … but rather the logic of color concepts".
The evening has a shiny modernity and Hytner assiduously follows the logic of his concept.
