Entering the Factory
When you are familiar with the general science of Mechanics, you will not feel foreign in any factory. Since you are aware of the general principles and secrets, you will soon be able to comprehend that factory and, with time and attention, you will become an expert in its affairs. How different are your understandings compared to a person who does not have the slightest idea of Mechanics? When that person enters a factory, he will be staggered by all the ample and sophisticated corners and sections and particles of the complicated machinery. He will be confused, and he will leave the factory with a sense of distress and inconvenience governed by his ignorance and lack of wisdom while having achieved nothing. Which do you suppose is better?
