Why science is the evil of which the priests warned

Yes. Plants, for example, seem to understand what the words “true” and “false” mean, but, of course, they do not, because they have no nervous system. They do not need to understand what “true” and “false” mean. But they act and react as if they understood the meaning of “true” and “false”. And by the way: their actions and reactions are averagely more successful than those of the living beings with a nervous system.
