This essay reshapes our understanding of the origin and trajectory of the phenomenology of feelings. In contrast to accepted interpretations, I show that Husserl's 1896 manuscript, "Approval, Value, and Evidence"-and not his 1901 Logical Investigations-is the foundation of his subsequent phenomenology of feelings, as it is found in Lectures on Ethi...

WRITING AND TRANSCRIBING: A GRAPHIC SYSTEM FOR SIGN LANGUAGES.
No genuine writing system has ever been developed for sign languages because of the issue of representing their spatial and multidimensional nature. Unlike for spoken languages, no rupture in modalities between oral and writing (gesturing visual) appears for sign languages (SLs). The sh...

Transformations are much used to connect complicated nonlinear differential equations to simple equations with known exact solutions. Two examples of this are the Hopf–Cole transformation and the simple equations method. In this article, we follow an idea that is opposite to the idea of Hopf and Cole: we use transformations in order to transform si...
