Western philosophy regarded emotion in varying ways. In stoic theories it was seen as a hindrance to reason and therefore a hindrance to virtue. Aristotle believed that emotions were an essential component of virtue. In the Aristotelian view all emotions (called passions) corresponded to appetites or capacities. During the Middle Ages, the Aristotelian view was adopted and further developed by scholasticism and Thomas Aquinas in particular. There are also theories of emotions in the works of philosophers such as René Descartes, Niccolò Machiavelli, Baruch Spinoza and David Hume. In the 19th century emotions were considered adaptive and were studied more frequently from an empiricist psychiatric perspective.

Later that summer, the Russians invaded Memel with 75,000 troops. Memel had one of the strongest fortresses in Prussia. However, after five days of artillery bombardment the Russian army was able to storm it. The Russians then used Memel as a base to invade East Prussia and defeated a smaller Prussian force in the fiercely contested Battle of Gross-Jägersdorf on 30 August 1757. However, it was not yet able to take Königsberg and retreated soon afterward. Still, it was a new threat to Prussia. Not only was Frederick forced to break off his invasion of Bohemia, he was now forced to withdraw further into Prussian-controlled territory. His defeats on the battlefield brought still more opportunist nations into the war. Sweden declared war on Prussia and invaded Pomerania with 17,000 men. Sweden felt this small army was all that was needed to occupy Pomerania and felt the Swedish army would not need to engage with the Prussians because the Prussians were occupied on so many other fronts.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How did the Russians used the captured Memel?
Ah, so.. used Memel as a base to invade East Prussia

At the beginning of the Three Kingdoms era (220–280 CE), Zhejiang was home to the warlords Yan Baihu and Wang Lang prior to their defeat by Sun Ce and Sun Quan, who eventually established the Kingdom of Wu. Despite the removal of their court from Kuaiji to Jianye (present-day Nanjing), they continued development of the region and benefitted from influxes of refugees fleeing the turmoil in northern China. Industrial kilns were established and trade reached as far as Manchuria and Funan (south Vietnam).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Along with Manchuria, where did trade reach as far as?
Ah, so..
Funan
