How is parallelism used here to strengthen the argument?

Parallelism is the repetition of similar grammatical forms. It is a powerful tool in public speaking and writing.

You may have heard this quote attributed to Julius Caesar:

I came, I saw, I conquered.

Throughout history, many famous leaders have used parallel structure to communicate with the public. Here is a famous saying by Abraham Lincoln:

You can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time.
