When you plant a fertile meme in my mind you literally parasitize my brain, turning it into a vehicle for the meme's propagation in just the way that a virus may parasitize the genetic mechanism of a host cell.
Interpretation
The quote illustrates how ideas can spread and replicate in our minds like viruses, influencing our thoughts and behaviors.
In this quote, Richard Dawkins compares the process of idea transmission to the way viruses infect host cells. He suggests that when a powerful idea or 'meme' is introduced to someone's mind, it can take over their cognitive processes and proliferate, much like a virus that hijacks a cell's machinery to reproduce itself. This analogy emphasizes the contagious nature of ideas and how they can manipulate our thinking, underscoring the significant impact that influential concepts can have on individual and collective thought.
In practice
In a discussion about social media's effect on culture, this quote can highlight how ideas spread.
No educated person believes the Adam and Eve myth nowadays, but it's surprising how many parents think that it's somehow fun to pass on this falsehood to their children...I would want to argue that the truth of evolution is more interesting and more poetic
If the history-deniers who doubt the fact of evolution are ignorant of biology, those who think the world began less than ten thousand years ago are worst than ignorant, they are the deluded to the point of perversity.
The population of the U.S. is nearly 300 million, including many of the best educated, most talented, most resourceful, humane people on earth. By almost any measure of civilised attainment, from Nobel prize-counts on down, the U.S. leads the world by miles.
When you make machines that are capable of obeying instructions slavishly, and among those instructions are 'duplicate me' instructions, then of course the system is wide open to exploitation by parasites.
Even if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.
The bitter hatreds that now poison Middle Eastern politics are rooted in the real or perceived wrong of the setting up of a Jewish State in an Islamic region. In view of all that the Jews had been through, it must have seemed a fair and humane solution. Probably deep familiarity with the Old Testament had given the European and American decision-makers some sort of idea that this really was the historic homeland of the Jews.
My practise as a scientist is atheistic. That is to say, when I set up an experiment I assume that no god, angel, or devil is going to interfere with its course; and this assumption has been justified by such success as I have achieved in my professional career. I should therefore be intellectually dishonest if I were not also atheistic in the affairs of the world. And I should be a coward if I did not state my theoretical views in public.
Quantum mechanics is certainly imposing. But an inner voice tells me that this is not yet the real thing. The theory says a lot, but does not bring us any closer to the secrets of the "Old One." I, at any rate, am convinced that He is not playing at dice.
NASA has spin-offs, and it's a huge and very impressive list, including accurate and affordable LASIK eye surgery.
An Experiment, like every other event which takes place, is a natural phenomenon; but in a Scientific Experiment the circumstances are so arranged that the relations between a particular set of phenomena may be studied to the best advantage.
I profess to learn and to teach anatomy not from books but from dissections, not from the tenets of Philosophers but from the fabric of Nature.
Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.
