Now People and Then People
Sydney J. Harris "Don't you want to be one of the Now people?" asks an ad for a new soft drink, going on to urge, "Become one of the Now generation!"
The only thing I can think of that is worse than being one of the Now people is being one of the Then people. As a member of civilization in good standing, I reject both the nowness and the thenness of the generation. I opt for the alwaysness.
To be a Now person means to be wholly concerned with the present and the immediate future; to be involved in fads, sensations and the whole pulsating ephemera of what's-going-on; to be perpetually on the qui vive (on the alert) for the newest, the latest, the coolest, the in. It also means to be insensitive to the past, to cut oneself off from the roots of tradition, to favor the sensory and the subjective over the rational and the real, to become a new kind of technological barbarian, which is more frightening than the old kind of preliterate barbarian.
To be a Then person means to cling to the past for its own sake, to apply lessons that are not relevant today, to engage in a mixture of nostalgia, envy, rage, and fear toward "modern youth", and to imagine that twentieth-century problems can be solved by sixteen-century moralism or eighteenth century politics.
These are false alternatives, for they are not exclusive alternatives. There is a better way than either, and that is to be an Always person, transcending both the frantic cult of the new and the feeble cult of the old. This means selecting from both what is valuable, and discarding what is useless or harmful —which, of course, implies the ability to such judgments. It means, further, learning to discriminate between values that permanent and universal and mere matters of convention or taste or the times.
The Always person does not throw out the baby with the bath water as the Now person does —who thinks that because we have had a false and hypocritical morality in the past that therefore all morality is merely a matter of taste or preference. Nor does he, like the Then person, operate on the basis that everything that was true for previous generations is equally true and relevant today.
Life is primarily the art of selecting and combining, not accepting or rejecting and philosophy in toto. The Now generation rejects the past too categorically, just as the Then generation embraces it too hysterically. To be an authentic person, in any age, means in some way to surmount the age and stand for the kind of order that permits and encourages graceful change.
