A Note on Bosbach’s Cone Algebras

In 2002, Dvure?enskij extended Mundici’s equivalence between unital abelian l-groups and MV-algebras to the non-commutative case. We analyse the relationship to Bosbach’s cone algebras and clarify the rôle of the corresponding pair of L-algebras. As a consequence, it follows that one of the two L-algebra axioms can be dropped.

Note on the generalized form of Weber’s Law

Institute for Perception, Soesterberg, Netherlands In this note it is argued that Δ I = k (I + I_n)P as an expression for the generalized Law of Weber (Treisman, 1964) is confusing. The expression ΔI = kIP + i_n should be preferred in the light of the evidence available.

Jung’s Axioms: An Introduction to Jung’s “Note on Number”

Kant’s virtue theory

By focusing on human virtues rather than the general morality of rational beings, Kant’s virtue theory presents systematic arguments from the perspectives of reason and experiential emotion, norms and disposition, spirituality and humanity, etc., which is of great significance to an overall understanding of Kantian ethics, thus clarifying misunderstandings from the past decades.
