The famous aphorisms about the experimental spirit are:

1. If we admit failure too readily, we may not realize that we are very close to being right.

2. The same is true for "difficulty". Facing a cliff, you won't be able to see a crack in a hundred years, but with an axe, you can make an inch forward. If you keep accumulating, you will make a leap and a breakthrough. Followed.

3. The ocean of truth allows me to explore all the undiscovered things.

4. The benefits of error are temporary, while the benefits of truth are permanent. When truth has defects, these defects will soon be eliminated, while the defects of error will always accompany the error.

5. Anyone who takes the truth lightly in small matters is also untrustworthy in big matters.
