The computer's keyboard was almost at his elbow. He stared at it for a moment, then slowly typed:

DATA: WIND OUT OF THE NORTH, WAVE FACTOR 0.50 ROUGHNESS SCALE.

INSTRUCTIONS: SUGGEST ACTION.

The machine chewed on the entry noisily for a few seconds, then answered: INSUFFICIENT DATA.

He nodded thoughtfully. That was his predicament too: insufficient data about his own motives. How could a man trust himself to judge wisely, when his judgement went completely against that of his society? He typed again.

DATA FOR HYPOTHETICAL PROBLEM: YOU HAVE JUST SOLVED A NAVIGATIONAL PROBLEM WHOSE SOLUTION REQUIRES COURSE DUE WEST. THREE OTHER COMPUTERS SOLVE SAME PROBLEM AND GET COURSE DUE SOUTH. MALFUNCTION NOT EVIDENT IN ANY OF FOUR COMPUTERS.

INSTRUCTIONS: FURNISH A COURSE.

The computer clattered for awhile, then typed: SUGGESTION: MALFUNCTION INDICATORS ARE POSSIBLY MALFUNCTIONING. IS DATA AVAILABLE?

He stared at it, then laughed grimly. His own malfunction-indicator wasn't telling him much either. With masochistic fatalism he touched the keyboard again.

DATA NOT AVAILABLE. FURNISH A COURSE.
