Because of the proliferation and aggressiveness of the communications media, men and women today have greater need than those of earlier generations to guard their thinking against intrusions from without. Just as modern governments find it necessary to take elaborate precautions against foreign spies and saboteurs, so the individual must be constantly on the alert to detect and thwart any attempts at interference with the natural clarity of his thought processes.
Fortunately, those who have learned to think with the precision of Christian Science are well equipped to do this. Realizing, as they do, that man's thoughts are naturally the reflection of the divine Mind, they are not responsive to specious and unprincipled suggestions, and they can assert and prove their independence from any falsely imposed beliefs.
The first step in this process is detection of the intruder. It sometimes comes in disguise. For example, the impulse to hate may clothe itself in the robes of righteous indignation. The urge to lie about one's income may appear to justify itself as a protest against unwise government expenditures. And in many other ways evil may try to don the garb of conventional compliance because "everyone is doing it."
