I'm always suspicious of memes. They often suggest a complex topic and distill or distort it down to a single pithy statement. To increase credibility, the statement is often presented as a quote by someone famous. I never trust any uncited quote on the Internet. Anyone can make anything up, put it on an image, and have it seen worldwide. Because of easy misattribution, a quoted meme is of no value. This is the problem with social media in general. The content is full of lies, and the targeted public is too stupid or naive to question what they are reading.
Some sources will actually cite their quotes on memes. The Bertrand Russell Bertrand Russell site is one. I am not terribly surprised that I would see a source quoting Russell with citations. Russell was an exceptional thinker. Anyone who reads him or takes an interest in his thought is a remarkable person also.
