Quote by Peirce, Charles Sanders

"The mind of man is not a thing to be studied apart, but as an integral factor in the natural world."

"Belief is not something that forces itself upon us. Belief is something we can control."

"The essence of belief is the establishment of a habit."

"There is one thing even more vital to science than intelligent methods; and that is, the sincere desire to find out the truth."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
