By simple observation and logic, we know these facts:
1. Every goal has the best possible path to achieve it.
2. Those who search for such path the most, and those who consider the most paths, are most likely to find the best path.
Survival of the fittest isnt, as some may think, circular reasoning theory.
Some think its a circular reasoning because "they survive because they are fit, and they are fit because they survive".
At first look, it seems like a theory which tells you nothing, because it doesnt tell you anything about what is necessary for survival.
However, the theory is proved by simple observation of general way of things.
For example, if survival is a goal, then it stands obvious that there is the best path to achieve that goal.
Those who take the best path will survive the best.
Its like with all other things in life, and just like any other goal, survival has the best path person can take to achieve it.
There are also the worst paths which guarantee that you wont survive.
Since survival of society or group is a goal which obviously has the best path which must be followed to achieve it, then it follows that only those societies who follow the best path towards that goal will survive.
Same applies to ideas and ideologies. Only those ideas and those ideologies which follow the best path towards survival will survive in the minds of the people.
Thus, not all can survive because not all follow the best path.
The survival, of course, doesnt mean mere existence but it also means the multiplying of the same.
When it comes to multiplying, only some ideas can multiply and conquer the world. Only some ideas are on the best path, or part of best path.
Thus, when the idea is part of the best path, it multiplies and conquers the world.
When idea takes the best path, it conquers the world.
Thus, for conquering the world, it takes the best path, the best idea.
Those who produce the most ideas are, by mere statistics, most likely to produce best ideas, ideas which are on the best path to conquer the world.
Thus, we see that some ideas are largely unknown, while some ideas are known to almost everyone.
So some ideas obviously spread better than others, some are part of the best path to achieve the spreading of those ideas throughout the world.
Thus, if goal is that idea conquers the world, only the best ideas can do that, only those ideas which are part of best path to achieve the goal of those ideas conquering the world.
To say it in simplest way possible, both quantity and quality of ideas is important.
Quality, because only ideas which have certain qualities, which are part of the best path, can conquer the world.
Quantity, because producing greatest number of ideas increases the odds that one of them will conquer the world.
