The Enlightenment Question 18 options: Reinforced religious doctrine and metaphysics in resistance to modern trends of secularism Substituted reason for doctrine, agency for fatalism, independence for obedience, scientific method for superstition, and attention to self-agency over ideas of predestination Understood that the events of history were not chance occurrences but events that served to carry out a divine plan. Led to the idea that life, politics, economics, and society are about self-seeking, personal interest satisfaction, and the idea that such behavior will necessarily redound to the public good B & D

5.9 This exercise relates $L^2(\mathbb{R})$ and $L^1(\mathbb{R})$. (i) Show that $L^1(\mathbb{R})$ is not a subspace of $L^2(\mathbb{R})$ (Hint: find a concrete function belonging to $L^1(\mathbb{R})$ but not to $L^2(\mathbb{R})$). (ii) Show that $L^2(\mathbb{R})$ is not a subspace of $L^1(\mathbb{R})$ (Hint: find a concrete function belonging to $L^2(\mathbb{R})$ but not to $L^1(\mathbb{R})$). (iii) Assume that $f \in L^2(\mathbb{R})$ has compact support. Show that $f \in L^1(\mathbb{R})$; in particular, this shows that $L^2(\mathbb{R}) \cap C_c(\mathbb{R}) \subset L^1(\mathbb{R})$.
