Question: This reaction is combined with an aldol condensation to produce cyclohexenones in a process named for Robinson, and a variation of this uses silyl ethers and titanium tetrachloride, in a reaction named also for Mukaiyama. In a process analogous to this reaction, performed with simple ketones, the equilbrium is shifted towards the reagents, unlike in the Claisen and aldol condensations, necessitating the use of an enolate in conjugate addition to produce the 1,4-addition. For 10 points, what is this reaction named for an American chemist, which consists of the addition of a carbanion to an alpha, beta unsaturated carbonyl

Question: This philosopher anticipated the theory of speech acts through his concept of the mode of quality that defines the psychology of a given action. While Bernard Bolzanos Platonic thought influenced his professional works, his final period as a student was under the author of Psychology of Tone, Carl Stumpf, who influenced this mans early mathematical works On the Concept of Number and Philosophy of Arithmetic. His first major work begins by debunking psychologism and goes on to a six-part descriptive psychological exploration of mereology, intentionality, and the relationship between truth, intuition, and cognition, among other topics. This author of Philosophy as a Rigorous Science collected his Paris lectures as another major book. For 10 points, name this author of Logical Investigations and Cartesian Meditations, credited with founding phenomenology.
