There is no need to say more. We have all experienced this transformation which takes place in the work of the brain. It enters on another phase when the wine begins to circulate. If we had not already met the guests on similar social occasions, we should be greatly surprised at their metamorphosis, and feel constrained to correct previous misconceptions of their character. Men, whom I had always thought silent and cold, I have seen, to my amazement, carrying on the most daring discussions with brilliant fluency, and rebutting sarcasms with such promptitude and success as to earn them loud applause. Other timid ones, known to all as slow, tiresome, clumsy talkers, find in the wine-glass a sparkling vivacity, a flow of speech which makes them more agreeable; nor do they hesitate to propose toasts and drink to the health of each of the guests. They rise, glass in hand, finding a witty word for each and showering compliments on all sides. Men, calm and sedate, in whom none suspected a poetic soul, are capable of rising and improvising verses, and we are full of admiration at their skill, and at the harmonious grace of rhythm, metaphor, and rhyme. Each one feels something like inspiration within him, as though warmed by the quickening pulse of life. But let us leave the joyous company: so far as our psychological study is concerned, we have already lingered too long, and it would be superfluous to follow them as they leave, in order to see how confident, kind, and courageous they have all become. The next day each will resume his own character and his own business. If it happens that one of the guests meets another in the street, they smile as they shake hands, and words which are a revelation are heard: 'We were a lively party last night, eh? I scarcely recognised _you_, and as for some others, there was no keeping them quiet!’ IV The analysis of memory better than anything else shows us the connection between the various parts of the brain which enter into activity in order to provide us with the elements that form speech. We must distinguish two kinds of memory: 1. The fixation of impressions, whether these be images, or representations of movements, words, sounds or sensations. 2. The re-awakening of these impressions as recollection.
