Tell me what is post hoc ergo propter hoc?

It means "After that, therefore on account of that". It's a label given to the particular error in logic where we decide that something happened after a certain even, so the event must have caused it. Examples: -- I have this gold ring that I keep in my pocket. I get up early every morning and I rub the ring three times, and within a few minutes, the sun rises. I feel good that I'm able to do so much for the world, especially for roosters, surfers, and farmers. -- My cousin's pediatrician's mailman's barber used to get a lot of kidney stones. Four years ago, he started drinking a cup of lemon juice every day, and he hasn't had any more since then. I'm going to write and tell Dr. Oz about this new miracle cure.

Dr. jekyll he told it cause it happened to him
