Tyger Tyger, burning bright,
In the forests of the night;
What immortal hand or eye,
Could frame thy fearful symmetry?
William Blake.
Our modern society is in love with Darwin. Our ideas about nature, evolution, society and ourselves have been shaped by this man. It seems like every reasonable person in the world agrees that Darwin’s theory is correct and useful. Darwin’s theory aims at explaining how species evolve and become new species through the means of what he called “Natural Selection”, which was defined by him as follows: “This preservation of favourable individual differences and variations, and the destruction of those which are injurious, I have called Natural Selection”. In other words, traits that benefit the individual tend to be preserved over time, while injurious traits tend to disappear. Traits that are not beneficial or detrimental are not affected by Natural Selection.
The accusation that this definition is tautological is nothing new and is well known, but it is generally ignored. A tautology is a statement that is true in every possible case. For instance, a statement like “The car is red because it’s not green” can’t be false because everything that is red is, by definition, not green. This statement is true but it’s useless as an explanation because it doesn’t give any information other than what is implied by its terms. Darwin’s critics accuse him of crafting a tautological statement because in his definition “favourable” or “beneficial” traits are defined as those that are preserved, and traits that are preserved are of course those that are favourable or beneficial. In other words, what Darwin says is that traits that are preserved are preserved. For instance: A Darwinist would say that human thumbs exist because they provide an advantage for the survivability of the species, so humans with thumbs have always been more successful at being alive and passing on their genes than human species without them. But if humans had no thumbs we could make the exact same argument, mutatis mutandis. Because of course what already exists has a higher chance of continuing to exist than things that no longer exist or that have never existed. Another example: Individuals who are born with healthy reproductive organs are more likely to pass on their genes than individuals who are born infertile. In both cases we can see “natural selection” in action. Both “explanations” are obviously true, but they are tautological, they don’t add any new information.
So the theory of Natural Selection explains nothing, and while scientists and biologists may admire Darwin and “believe” in Natural Selection, especially in opposition to creationist explanations, the truth is that Darwin’s book On The Origin of Species is an artifact of the past and university curriculums hardly devote any time to it. If people were to suddenly forget all about Darwin our understanding of evolution would remain roughly the same - although we would lose his contributions in other fields. Nowadays people seem to think that “evolution” and “natural selection” are synonyms but that’s not true at all. Evolution wasn’t a new concept to educated people back in the XIXth century, and everyone grasped the concept of heritability. So why was it so important, or why was it considered important, and why did it cause such a revolution in our understanding of nature? The answer is: Because of the concept of struggle for existence. People have always known that animals and humans change throughout the generations, but Darwin’s theory asserted that everything in nature, both animal and human, is determined by a struggle for scarce resources, that is, by an economic problem. Again, this is something that everyone who has felt hunger or desire to reproduce has understood to some degree, but before Darwin nature was much more than simply being alive and reproducing yourself. It was a divine creation, it had meaning, it had truth, it spoke in a rich language understandable to humans. Darwin’s theory made this language unintelligible, because it showed that an economic mindset was enough to understand nature for the purpose of fulfilling our needs. If a car is red, we don’t need to know the owner’s preferences or the manufacturer’s motivations in order to know that it is not green, and this knowledge is enough to use it. The fact that humankind descends from apes was polemic only because it showed that humans and apes have the same needs and aspirations, even if they had different evolutionary strategies to acquire them. But this is the conscious part, the part that everyone acknowledges. There’s also an unconscious consequence of the theory of natural selection: That nothing exists outside the struggle for existence.
This last idea is what makes Darwin’s theory so apt for the modern world. Science can overcome Darwin, modern society seemingly cannot. And even though biologists don’t pay much attention to him, Darwin is still quite popular in politics, philosophy, and social sciences. Because if there’s something at which modern society is particularly good, it’s at providing the means for existence and reproduction. So a theory of nature that asserts that this is all there is to it it’s bound to be popular, because it justifies the current state of affairs and exalts it as the best possible outcome of a long evolution towards an efficient society. All other possible alternatives are overcomed, and any possible development can only follow its example. Politically, liberals love it because it justifies and naturalizes their belief in the free market, and marxists love it because it promises future and exciting developments when men conquer the course of the evolution of their species with their own hands. Philosophically it solves the problem of how living creatures were created out of lifeless things, and it solves it in such a way that is comprehensible for human cognition. But the most peculiar development comes from the social sciences. First, came the social Darwinists who tried to apply the principle of survival of the fittest quite literally, but after WWII this became impossible for political reasons. We now have evolutionary psychology, a field that instead of trying to control human behavior creates a mythology around it, providing panglossian theories for human behavior that explain nothing and are therefore impossible to prove or disprove, but that provide a common ground between the general public and solicitors, drivelers, quacks, pickup artists - in a world, charlatans of all kinds. Everybody wants the secret to “hack” human behavior. There’s a particular internet subculture of men who are frustrated with modern society and with the changes in gender roles, and who look in evolutionary psychology for mating strategies to end their loneliness, believing that the atavistic caves where man supposedly learned to be man are like the rooms in which they spend most of their lives, without realizing that it is the selfishness of modern society that created this idea of the primitive caveman and that erodes human connections by reducing them to a mere survival strategy.
But it is clear that man became man not by surviving or by conquering the means to preserve and reproduce himself, but by the conquest of the unnecessary. As Gaston Bachelard(1) puts it: “Man is a creation of desire, not a creation of necessity”. Furthermore, there’s no evidence for the existence of a “survival instinct” anywhere in nature. We believe ourselves to be smarter than animals because they risk their lives in pointless endeavors, they are mostly unable to plan ahead and to cooperate for their survival as we do. But who said they needed to? If everything life needed is to survive, then asexual organisms would be the pinnacle of evolution, everything that has come after it is useless and inferior by this standard. While it is true that a struggle is necessary to exist, if existence were its only goal, if one could not risk even existence itself in exchange of something else, this struggle would be meaningless. Sexual reproduction is an example of a struggle where individual existence is put into question, because it bridges the gap between two individuals and creates something new. It is luxurious and exuberant, as life itself. This is something that has always been quite clear for humans since the dawn of time, but that seems incomprehensible now. Biology can progress through Darwinism but only by obscuring the mystery of life, turning it into something miserable and petty, like human economy. This progress is nothing but a change of perspective, focusing one thing and ignoring another. But as all perspectives are, in principle, equally valid, it’s only desire what moves us towards something else and something better than our trivial everyday existence and its meaningless struggles. Is it not, as Georges Bataille puts it, the tiger’s fruitlessness what makes it the king of the jungle? By predating on other animals, that eat other animals, that eat plants, and so on, the tiger splurges a huge amount of the jungle’s resources. Some would say that it serves the purpose of maintaining the balance of the ecosystem, but couldn’t this balance be imposed by the tiger itself? Its existence would then be more than a struggle for existence, it would be a struggle to impose its own norm, its own will, its right to splurge. This struggle would be unintelligible without the base of mere existence, because individual existence imposes a period of activity and silence, a discrete grammar for the tiger’s individuality to express itself, but the meaning of the tiger’s behavior can only be confused with its grammar by a fool. The tiger itself is but an echo of something infinite.

Notes -
The initial objection feels a little like saying '2+2=4 is tautological because our mathematical system defines it to be so, therefore it's a meaningless statement of no value.'
Sure, the model defines numbers and operations such that 2+2=4 is tautological within the model.
The interesting theory is that this model accurately describes some aspect of reality. Which everyone before Darwin would not have expected his model to do.
That's generally true of hypothesizing models to describe reality. It's not a knock on a model that it is internally consistent and complete.
You are right, if we look hard enough we can find a tautology at the root of all human knowledge, but they are generally useful to study a share of reality. 2+2=4 may mean the same as 4=4, but by changing the terms you are providing new information: That this operation may be written differently. Pragmatically we can use this to explain many things. But when Darwin says that traits that favor the preservation of the species are preserved, no new information is gained. It describes an aspect of reality, but in terms that don't imply anything beyond themselves. Saying that everything that is red is not green accurately describes reality as well, but pragmatically fails at explaining anything.
To someone who thinks that traits are not passed down, it is. Someone might think that the distribution of traits in cats today are the exact same as the distribution of traits in cats 5000 years ago.
Also, there are interactions between traits. Say someone has a mutation that removes their thumbs, but has another mutation that makes them a super genius. Are they more or less likely to pass down their traits than an average person with no unusual mutations? Understanding Darwin's theory is the first step to understanding the exceptions, to understanding why detrimental traits are passed down sometimes.
5000 years ago people knew that short haired cats had short haired offspring. Entire empires and civilizations were created out of the concept of inheritance. What people lacked was the theory of genes, but Darwin lacked that as well. Darwin does not explain at all why detrimental traits are passed down, if we were to prove then Darwin's theory would be false. But we cannot prove that things that don't exist are preserved. If something exists then it is 1. Benefitial, 2. Bening, or 3. Extinted/In process of disappearing.
Yet no one put together the theory of natural selection. People also knew objects fell when you dropped them, but it took millennia for people to really start formalizing it.
Or 4., linked to another trait that is beneficial, such that the two traits are passed down together.
Darwin's theory let him make predictions about nature. Before him, people weren't making predictions about nature, about how different environments would lead to different traits being more prevalent.
No one had put together the theory of natural selection before because we had to wait for Malthus to publish his Essay On The Principle Of Population. We also had to wait for industrialization and secularism to come up with the idea that nature is bound by economic principles. As I said, Natural Selection explains nothing, the concept of Struggle for Existence is what made Darwin popular and different from other biologists.
Regarding your other statement, 4. would just be 1. with extra steps. And yes, people did make predictions about nature, they did it all the time. In fact, agriculture is based on the observation that certain conditions produced changes in the species that were benefitial for humans. You'd be surprised how "modern" some ancient thinkers were.

Other thinkers had some good ideas, but they didn't come up with Darwin's.
Other thinkers had some good ideas, Darwin did as well but this is not one of them.
