Substitution Ciphers

This is a simple substitution cipher, where I have randomly chosen one letter to represent another. Ciphers are where one character represents another. In codes, one character or symbol can represent a group of letters or words, so all emojis are codes, for example.

ZW  VEPONHN  MDNVZBNYY:

YZVDZ  JPNDN  SWG  VDN.

GYN  JPVZ  SWG  PVHN.

TW  JPVZ  SWG  EVB.

Can you tell me which great man said it?

Tip: The most commonly used letters in the English language are:

As with all averages, these apply best to large samples, but they often help us to crack ciphers and codes.
