Spinoza vol 1 ebook Chapter 12: How Spinoza’s Conatus Fares Against Darwin’s Theory, the Pizzly Bear Example



Further to the previous chapters, I suggest that Spinoza’s reworking of divine teleology also informs his views on whether human behaviour and events in nature are also teleological or not. I think Spinoza is claiming that both human behaviour and nature are not teleological. This is because, as I mentioned earlier, firstly, they arise from all that flows from God’s nature[i] and secondly, because these phenomenon can be better described by his account of how things in the world strive to persevere in their being[ii]. By not restricting his account to specific, teleological goals to explain human behaviour and the natural world around us, he builds in a flexibility into his account that Aristotle and Maimonides didn’t have. In contrast to Della Rocca's view, I think this flexibility of telos means we can read Spinoza as being consistent in his rejection of all types of teleology, including in relation to human behavioural psychology[iii].

I think this also means that Spinoza is a ‘forerunner’, for want of a better word, to Darwin’s theory of evolution. This is because his account of striving to persevere in one’s being describes our conatus in a flexible, adaptive way which flows from our nature and relates to our instinctive desires. Thus his account matches up with Darwin’s theory of survival instincts, survival of the fittest and generational evolutionary adaptation to one’s environment, for both individuals and perhaps passed epistemically and socially down the generations. I think Spinoza’s account of the conatus also compares interestingly with Darwin because Darwin’s theory is not only a scientific one but has a societal aspect to it as well. This may be because Darwin writes that he was, in part, inspired by Malthus’ social theory and applied it to his theory of evolution, especially in his chapter ‘Struggle for Existence’ in his ‘Origin of the Species’ (originally published 1859)[iv]. There is good textual evidence for this because Darwin summarises his use of Malthus’ theory thus in his preface to this book:

“This is the doctrine of Malthus, applied to the whole animal and vegetable kingdoms. As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected.”[v]

I would also suggest that what is often interpreted as egoism in Spinoza’s writings[vi], may instead be an observational account of the natural world and society that is trying to capture the problem of survival rather than egoism. Thus the Spinozian concepts I examined earlier of striving and struggling for continued existence may be somewhat along the lines of what Darwin describes in his preface to his ‘Origin of the Species’:

“As natural selection acts by competition, it adapts the inhabitants of each country only in relation to the degree of perfection of their associates; so that we need feel no surprise at the inhabitants of any one country, although on the ordinary view supposed to have been specially created and adapted for that country, being beaten and supplanted by the naturalised productions from another land. Nor ought we to marvel if all the contrivances in nature be not, as far as we can judge, absolutely perfect; and if some of them be abhorrent to our ideas of fitness.”[vii]

Darwin’s theory can be seen as, inadvertently or otherwise, supporting Spinoza’s dissatisfaction with notions of fitness with biological examples such as use and disuse. For instance, a calf pre-birth has teeth in its gums that will not grow into functioning teeth when it matures because such teeth have fallen into disuse over the generations[viii]. This refutes Aristotle’s notion of usefulness and his argument for a teleological, fixed, immutable final cause that explains why things are as they are in the world[ix]. Indeed, in his preface to his ‘Origin of the Species’, Darwin explicitly rejects Aristotle’s explanation of the purpose of teeth, when writing “We here see the principle of natural selection shadowed forth, but how little Aristotle fully comprehended the principle, is shown by his remarks on the formation of the teeth.”[x]

Hence, Spinoza’s psychological-biological account of human striving without a fixed, teleological end allows for organisms to change, adapt and mutate. This, as well as the aim of dispelling prejudiced notions, are also key features of Darwin’s theory:

“A few naturalists, endowed with much flexibility of mind, and who have already begun to doubt on the immutability of species, may be influenced by this volume; ....Whoever is led to believe that species are mutable will do good service by conscientiously expressing his conviction; for only thus can the load of prejudice by which this subject is overwhelmed be removed.”[xi]

“Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation.”[xii]

Furthermore, I suggest that Spinoza’s account of our conatus, striving to persevere/continue in one’s being/existence and increasing one’s mental powers could be seen as being not only in line with Darwin’s theory of evolution but also, and to a greater extent, being a ‘forerunner’, as it were, to modern-day scientific theories, especially in the field of genomics. Until relatively recently, Darwin’s theories had only been supported by patchy fossil records and other evidence which was not very conclusive[xiii]. However, more recently, studies on DNA and genomic make-up are considered to support Darwin’s theory of evolution and provide the scientific evidence for his theory by looking at, for instance, genetic variation and how our genomic make-up also helps to give explanations of our nature, features, tendencies and behaviour[xiv]. Indeed, this can even inform our knowledge of emotion, including the emotion of fear[xv], which is an emotion that Spinoza gives a vital role to both in his Ethics and TTP. Our DNA may also impact on our survival instincts, how we adapt and react to our environment and so, in Spinozian terms, how we persevere in our being and strive to survive in the world. If this is the case, then this modern-day genomic account of human beings, I suggest, would suit Spinoza’s account of a non-teleological way of striving since the telos of our striving is not for a static, fixed, unchanging end goal or telos but rather a striving for whatever helps us survive and adapt, which are factors that drive the evolution of the species. This both fits with Darwin’s theory of evolution as well as modern day scientific accounts of evolution.

So, how would the various theories explored in this chapter apply to a practical example, such as the genetic hybrid animal the pizzly bear? Which would win out as the most plausible and successful at providing explanations of the world around us? I shall try to imagine how each of the views may respond to an example I found which I think works as a test case for my hypothesis.

Example: Due to global warming, the polar bear has become maladapted to its environment. So, it has migrated south and mixed, both socially and sexually with grizzly bears who are better adapted to the warmer climate. They have offspring together which are known as pizzly bears. They are genetically a hybrid of the polar and grizzly bear.  

An Aristotelian-style explanation for the pizzly bear:

The purpose of the polar bear’s coat is for keeping it warm despite the freezing weather in its habitat (purpose/telos of its coat). Just as the eye is for seeing, so the polar bear’s coat is for keeping it warm in its habitat.

This is not a satisfactory explanation: Global warming has changed the polar bears’ environment and their behaviours, aims, purposes, what they strive for and how they attempt to persevere in their being including what purpose their coat is for. Now it is not as useful for the polar bear to have an arctic coat of fur given global warming. This account doesn’t take into consideration that future generations of bears will socialise and interbreed together so the telos of their design will change accordingly over time.  So Aristotle struggles to explain the pizzly because he can’t keep pace with natural changes in the world.

A Maimonidean-style explanation for the pizzly bear: 

The polar bear has a white warm coat of fur because God in His infinite wisdom thinks this best for the well-being of the bear so has designed the polar bear this way and wills it to be the case. 

This is not a satisfactory explanation: This may undermine God’s infinite wisdom and omnipotence. Why did God design the animal in such a way that it cannot adapt to its future environments that He should have foreseen? Such apparent short-sightedness ruins God’s perfection. Also, if God is the only cause, then He both causes the global warming and the design of the bear yet the two will be in conflict with one another during some eras. Does this make God contradict Himself? Another Spinozian concern may be that it would be impossible to comprehend why God willed this since divine will and intellect do not resemble anything human-like (such as the Dog example in E. I. p17s[xvi]).   

A Darwinian explanation for the pizzly bear

Through natural selection, the polar bear is now struggling to survive more than the grizzly so gradually the polar bear may become extinct and adapt by mating with the grizzly. 

This explanation can only explain some of the phenomenon of the pizzly and not others. For instance, why did the pizzly not evolve and mutate over many generations gradually rather than appearing immediately as a result of interbreeding? So, Darwin’s theory of evolution can be too incremental and so explains certain modern theories, for example, mitochondrial Eve but can’t explain all cases, especially where there’s a more sudden discrepancy or development, for example, skull findings.

Genetic explanation of the pizzly bear:

The evolution of species is propelled by genetic variation. Beneficial characteristics such as the grizzly’s fur coat will be genetically selected and overall will out-live less beneficial features such as the polar bear’s fur coat and will be inherited by future generations ie the pizzly in the process of natural selection.

This is purely a scientific account and so wouldn’t help resolve the tension between science and religion which was an important issue in the seventeenth century and sometimes continues to be so today. Some genetic explanations still cite random chance and brute luck in their explanations of why people inherit some genetic traits and not others or have relatively broad-brush explanations of how environmental factors impact on genetic changes. I suggest it would be better to put such apparently inexplicable or difficult to explain phenomenon down to a current lack of knowledge rather than resorting to randomness and chance. There perhaps is some necessity involved which is merely difficult to explain until we discover, for instance, the relevant natural law for it and gain a better understanding of how that law behaves.   

Spinoza’s explanation of the pizzly bear in terms of their conatus striving to persevere in their being in a non-teleological way:

God is the cause of the polar bear coming into existence and how it continues to exist and act

Polar bear strives to persevere in its being

Polar bear struggles to persevere in its being (eg due to global warming, climate change). It will only go out of existence due to external causes (eg global warming) not internal causes (eg losing the will to live)

Polar bear needs to adapt, strive differently in a different way for different ends (conatus)

Polar bear needs different survival skills/knowledge/habitat and starts to socialize with grizzly bears who are now better adapted/persevere in their being more successfully in the polar bears’ environment than they do

Polar bears mate with grizzly bears and have offspring -pizzly bears- that are a genetic combination of the two bears which means they are better adapted to this new environment and they can persevere in their being and strive more successfully than their polar bear parent and their generation. The polar bear also has a better chance of survival because it has teamed up with grizzlies who strive successfully in warmer climates.

From this, I think Spinoza’s theory wins out as being the most all-rounded theory which encompasses all the issues and facts that need to be factored into a cohesive theory which aims at explaining various aspects of the world and God. So Spinoza is not just a forerunner to Darwin but, in addition, we can use his account to understand modern science because his theory predicts genetic explanations. I don’t think that Spinoza felt the same concerns or conflict between science and religion that many other thinkers have felt. Indeed, this may be partly because Maimonides himself thought that science and religion should always go hand in hand and so not diverge in their thought that much. In this way, I think Spinoza may have thought it was not heretical of him to provide an account that takes both religion and scientific thought into consideration simultaneously. Unlike Maimonides, however, he does not need to change his science or religion to make them coincide with each other. They merely function together interdependently and compatibly. If I am right in thinking that Spinoza may have believed in the possibility of constant creation, then even the theory of evolution and laws of nature would not pose a theological threat to him. For some it does, because they struggle with (seemingly random) evolution taking place without God’s will whereas for Spinoza, this is resolved by seeing the laws of nature and all that exists and happens in the world as flowing from God. Hence, in this way, we can study pure science without Aristotelian teleology and without clashing with the belief that God exists and is the first cause, which is a view with which Maimonides would agree.  

So, I suggest that Spinoza not only provides an alternative account to an ancient Greek and medieval one but also, in some ways, anticipates the structure of Darwin’s views. For, both Spinoza and Darwin claim that:

One, there are observable laws of nature to study

Two, humans and things in the world strive, adapt and change

Three, this striving, adapting and changing does not entail a fixed, static purpose they are suited to or involve an end goal or telos.

Therefore, I advocate that Spinoza attempts to circumvent the need for explanations in terms of final causes by:

Firstly, providing differently reasoned answers to questions about humans and the world

Secondly, by his type of axiomatic argumentation

Thirdly, by substituting the linear, futuristic, goal orientated final cause account with his interrelated accounts of eternity, God, nature, necessity, human desire, superstition, the intellect and the passions.
