The sexual impulse - next to the love of life - shows itself the strongest and most powerful of motives.
It is the ultimate goal of almost all human effort. It has had an influence on the most important affairs, interrupts every hour the most serious occupations, and sometimes perplexes the greatest of minds. It does not hesitate to intercede with its trash, and to interfere with the negotiations of statesmen and the investigations of the learned. It knows how to slip its love notes and ringlets even into ministerial portfolios and philosophical manuscripts.
Every day it brews and hatches the worst and most perplexing quarrels and disputes and destroys the most valuable relationships, and breaks the strongest bonds. It demands the sacrifice sometimes of life or health, sometimes of wealth, position, and happiness. Indeed, it robs of all conscience those who were previously honourable and upright, and makes traitors of those who have hitherto been loyal and faithful. Accordingly, it appears on the whole as a malevolent demon, striving to pervert, to confuse, and to overthrow everything.
(So) The ultimate aim of all love affairs, whether played in seriousness or fun, is actually more important than all other aims in man’s life; and therefore it is quite worthy of the profound seriousness with which everyone pursues it.
Now go discuss with that pretty co-ed across the hall. You actually have a legitimate excuse to talk to her about sex.
