If the religious community has focused more on proofs for the existence of G-d than for the existence of mankind, it is only because the former is denied far more directly than the the latter. We are told all the time to doubt the existence of human beings, but in subtler language. The question is not whether fuzzy bipeds walk the earth, speaking to each other, playing baseball, writing books, etc. The question is whether they’re human, that is, essentially distinct from all other beings. The voices ring out with a resounding No!: “A human being is just an ape plus details.” “A human being is just an artificial intelligence minus details.” “A human being is like any other localized set of particles plus (illusory?) details.”*
It is not (just) a particular disdain for human beings that motivates these arguments. We can hardly blame the contemporary thinker for denying human beings in particular if he denies all non-reductive essences in general; in fairness, he also says a frog is something else plus details, water is just two other things combination, and so on. The denial of human beings per se is just the subset of denying anything per se, of denying anything has essential characteristics making it what it is. This is, in most cases, called nominalism and may or may not be the scourge of modernity.
Whether there’s a particular ire for humanity or merely no apparent reason to exclude them from the illusory appearance of essences, the result is the same. In essence, the human being is a concept that needs defense, demonstration, proof. It would be extremely helpful to discover or rediscover arguments that point to something like the “essential nature” of the human being, something very much akin to a soul, as we shall see. Such an argument would preferably be logically sound, easily-conveyed, and rooted in easily-acceptable premises.
One such argument is dropped like a bomb in a short paragraph by David Berlinski on p.116 of his outstanding collection of essays, Human Nature:
A simple modal argument is sometimes of use in this argument; and if not of use, then carelessly neglected. If human beings are largely insignificant in the cosmos, then surely they are not necessary either. Krauss says as much explicitly. “You could get rid of us and all the galaxies and everything we see in the universe and it will be largely the same.” But if human beings are not necessary to the universe, then it follows that the universe is not sufficient for human beings. If ∼(∼Q⊃∼P) then ∼(P⊃Q). If this is so, anything that might reasonably be called a naturalistic explanation for the emergence of human life is beside the point. There could not be any such thing.
This “carelessly neglected” line of reasoning is directed toward those who would offer a “naturalistic explanation for the emergence of human life.” That is, it speaks to those who view humanity as something like a cosmic accident, a meaningless complication thrown out by impersonal universal forces for some infinitesimally short slice of time, preceded (in time or in importance) by eons and likely followed by infinity. This view is a subset of those who deny humanity per se; in this case, the human being is reduced to forces of nature plus details.
This sort of naturalist inevitably believes that human beings are not necessary to the universe. After all, if human beings were necessary, a built-in outcome of all those universal forces, then the forces would not be impersonal at all, but rather inherently geared toward producing not just life, but human life! They could do nothing else but result in human beings; humanity was baked into the universe from the beginning!
No, per the naturalist, human beings must be unnecessary, or merely possible, to the universe. The difference between being necessary to a prior state of affairs and being merely possible to it can be illustrated by two different recipes for cake. The baker for whom the cake is necessary to the recipe writes the following:
Chocolate Cake Recipe:
1 x Chocolate Cake
There is no outcome from these ingredients other than cake, and no other ingredients are required to produce the cake as an outcome. These ingredients inevitably yield cake, to the extent that the baker doesn’t even have to do anything. If we have the ingredients, we actually already have cake, just as when humans are necessary to the universe, they already exist in a certain sense from the moment time begins; we are truly inevitable.
The naturalist baker views the human cake as having a recipe more like:
Chocolate Cake Recipe:
2 x Eggs
4 Tbsp. Baking Chocolate
2 Cups Flour
None of these ingredients on their own is cake, and on the contrary, they must come together in a specific way under specific conditions (e.g., mixed together and then baked in a pan at 350 °) to yield cake as their outcome. The cake is not a necessary result of this recipe; if we forget the eggs or fail to mix the ingredients properly or don’t place them in a warm enough oven, there will be no cake. The naturalist claims, at the very least, that the ‘starting ingredients’ of the universe (e.g., matter, energy, forces) necessitate no human beings, that human beings could have or could not have existed just as easily as far as those starting ingredients care.
In truth, the naturalist claims the ingredients are not even ingredients except in retrospect when they happen to have created a cake. Ingredients imply that there is a purposive process intended to produce a certain result. The naturalist, as explained above, won’t have it. To them, the ordering “recipe” is an imposition of the human mind rather than an expression of qualities inherent to the ingredients. But to make this claim of purposelessness, one must already have concluded that human beings are not necessary to the universe, or in other words, that it could have turned out differently, with no human beings emerging on the scene at all.
Berlinski then makes a rather straightforward argument: If human beings are not necessary to the universe, then the universe is insufficient to produce human beings. In the language of our metaphor, if the resultant cake is not necessary to the second cake recipe, then the ingredients of the recipe are not sufficient to produce the cake.
In other words, the first recipe plus nothing equals its result. The second recipe, however, being a normal recipe, requires additional things to produce the result.** The ingredients alone are insufficient to produce the cake because if they alone were sufficient, we would have the cake already! Since we do not necessarily have the cake just because we have the ingredients, the ingredients are not enough to produce the cake on their own (without mixing, baking, etc.).
This leaves our friend the naturalist in a bit of a bind. On the one hand, the naturalist cannot say that human beings are necessary to the universe, like the first recipe, because that would imply human beings are as important as the entire universe; after all, the universe must produce humankind the way the first recipe must produce a cake. On the other hand, the naturalist cannot say that human beings are not necessary to the universe, like the second recipe, because that would imply the universe is insufficient to produce humankind, that the universe needs mysterious outside help to create a human being. Either we are a totally predetermined inherent reality to the universe, or the universe alone cannot create us at all.***
The naturalist’s description of us as insignificant accidents of nature seems, well, half-baked.
While Berlinski has not demonstrated the human essence or soul, exactly, he has given us a nudge in the right direction. He shows that understanding the recipe for a thing tells us a lot about it. When we say ‘recipe,’ we mean not only the material components but what it means for something to have a recipe, what it means for something to have a necessary or unnecessary effect, for its components to be sufficient or insufficient grounds.
As my teacher, Rabbi Yitzchak Kaufmann, points out, a similar argument to Berlinski’s is found in the Discourses of the Tzemach Tzedek, the third Rebbe of Lubavitch. This argument does speak directly to the human essence and the human soul. It is found in Torah Ohr, Bereishis, Hosafos p.434, and in Sefer HaChakira, p.63, and it starts like this:
In Midrash Rabbah, Parshas Bereishis, ch. 8, on the words (Genesis 5:2), “male and female He created them”:
Rabbi Yehoshua bar Nechemya says in the name of Rabbi Chanina bar Yitzchak, and the Rabbanan say in the name of Rabbi Eliezer: G-d created in humankind four qualities from above and four qualities from below. They eat and drink like an animal, reproduce and multiply like an animal, leave waste like an animal, and die like an animal. From above: They stand like attending angels, speak like attending angels, have knowledge like attending angels, and see [both to the front and to the sides] like attending angels.
In my opinion, we learn from this a demonstration of the soul’s persistence [after the body’s death], for Maimonides writes in his Guide for the Perplexed, pt. II, ch. 1, in the second argument, that when we see the composite of two components, and then we also discover one of these components alone, then certainly the other component exists on its own. For example, there is a honey/vinegar mixture, and when we know that honey also exists without vinegar, we may deduce from seeing honey alone that the mixture of honey and vinegar is not necessary. And therefore, we know that vinegar exists apart from honey. Even if we’ve never seen pure honeyless vinegar, we know it exists from the fact that we’ve seen honey alone.
What happens if we buy a cake made of eggs, flour, and chocolate, then later see eggs by themselves, without the other ingredients? This would prove to us, beyond a doubt, that our cake is not made with the first type of recipe mentioned above. The recipe for cake is not simply cake. Rather, it’s made with the second type of recipe. By seeing that eggs can exist on their own, we show that the cake is an unnecessary composite. If the recipe for cake is just cake, its ingredients always come together; you will never find an ingredient apart from the whole. Since we’ve discovered the eggs on their own, the cake’s ingredients must come together only sometimes, but not always. And if they don’t always come together, that means there must be chocolate out there, too. Even if I’ve only ever seen a cake and the eggs that are one of its ingredients, I know that these ingredients don’t always occur together, and so, at least sometimes, chocolate must exist without eggs.
So, if we knew that a human being was just such an unnecessary composite, we would know that a human being’s component parts must, at least sometimes, occur independently of one another.
Continues the Tzemach Tzedek:
So, too, in man, do we see a composite of animal and human life. Man has four qualities, as the Midrash describes, that are just like an animal’s, and four additional qualities that animals have not at all. This means man is a composite of the animal and the human. Even though the animal in man is more refined, it is still literally like that of an animal and equal to an animal in the four traits mentioned above. It is just that man has an additional four traits from above, knowledge and the faculty of speech, etc. And since we find the four animal traits in animals without the higher traits, from this we can judge the four traits from “above” to also exist on their own, without animal aspects.
That is, the “animal” [in man must be just] the physical body of flesh and blood receiving life, and therefore say that the four aforementioned heavenly traits of knowledge, speech, etc., exist without a physical body in abstract intelligences [e.g., angels]. And this is demonstrated through the above demonstration. And now, since the soul of man contains aspects from intelligences abstracted from matter, even if the animal soul does not persist [after the destruction of its physical matter], the human soul certainly does.
And even though we believe in this according to the Torah without any philosophical investigation or [need for] human intellect, as the verse says (Shmuel 25:29), “the soul of my lord shall be bound in the bundle of life” and (Zecharia 3:7), “I will permit you to move about,” nevertheless, nothing is lost by supporting it with this demonstration as well. And even though the philosophers bring other demonstrations for the soul’s persistence, this demonstration is supported by the above Midrash.
The Ephodi and ReSheT question our principle and say we indeed to find composites and one of their components alone without discovering the other component alone. [For example, a] man contained both life and speech, and life is found without speech, but speech is never found without life.
But according to what was said above in the name of the Midrash, on the contrary, this is proof for our point. Speech is found in man from above, i.e., in speech, he is like the attending angels, and it is about this that the verse says, “man is created in the image of G-d.” And if so, speech is found apart from life, that is, apart from bodily life, in the abstract intelligences.****
The human being is made of multiple components, multiple ingredients. These components do not exist as a necessary composite; that is, they can exist apart from each other, just as the eggs can exist apart from the cake. Just as man eats and drinks, for example, so does an animal. This shows that the various faculties of the human being do not have to coincide. But if the human being is not a necessary composite, this means that those aspects of man which do not occur in animals, like his abstract intellect or his ability to speak, must occur separately from the animal faculties of man as well. If the egg exists in a pure form unmixed with any other ingredient, so much the chocolate.
Not only are we either necessary to the universe or beyond its sufficiency, as Berlinski would have it. We are also human beings. We are not an ape plus details, or an artificial intelligence minus details, or any other being plus or minus a few incidental traits. All of these beings’ traits are bodily. In us, bodily traits exist in addition to unique human traits. Since the composite is not a necessary one, our unique human traits also must exist alone, apart from any bodily traits, persisting beyond (chronologically and spiritually) our body, the way a piece of chocolate persists beyond a chocolate cake.
This persistent collection of human traits constitutes human life and human identity, and may comfortably be called the human soul. If we have not found G-d, we have at least found ourselves. And that is a large part of finding G-d as well, if our holy teachers are to be believed.
* It has especially been the role of Darwinism to displace this essential distinction; other modern philosophies like transhumanism have merely rushed to fill the gap left by evolution’s assertion that species are infinitely malleable. This is what Darwin means when he writes (quoted in Berlinski p.109), “[W]e will have to treat species in the same manner as those naturalists treat genera, who admit that genera are merely artificial combinations made for convenience.” Since species can change into other species by a series of piecewise steps, the species themselves cannot be essentially fixed. Each species becomes like a genus, that is, a group of species. Philosophically, there is nothing below the genera in this system, which to this essentialist sounds almost like an infinite regress, a tower built on air, a bunch of zeros summed to produce not just one but all known numbers. Darwin, of course, did not invent the philosophical aspects of evolution in his theory; earlier, more coherent versions trace all the way back to the essentialist Plato. His influential theory of forms implies an order of being such that differentiating essences may be appended to shared common denominators. Aristotle’s definition of man as the ‘rational’ animal is a prime example. To him, animality is a true shared essence and rationality the distinguishing factor, such that man and animal are metaphysically “related.” The Talmud (in law) and Jewish philosophy and Kabbalah (in metaphysics) repeatedly deny this ‘accretion of forms,’ particularly due to their commitment to creation ex nihilo.
**In fact, this is what makes the second recipe a normal recipe; “normal” for finite beings like us means “something from something,” the creation of a new thing by multiple parties in agreement. When G-d makes the universe ex nihilo, from nothing, He does so as the sole party to the creation (and He does not and cannot count as a “something,” hence, “from nothing”). He says, “Let there be light,” and there was light, and what was the cause? G-d alone. Nothing in our reality works like this; when we make something, it is by actualizing an already-existent potential, by attaching form to matter. Thus, there can, in principle, be no recipe (in the cookbooks of the finite universe) with only a single ingredient and no further instructions; this is not a “recipe” but just a food ready to eat. When we say G-d creates ex nihilo, then, we are saying He creates with no ingredients and no process. It is not just impossible for us to understand because we’ve never seen it, but impossible to understand in principle; there is no answer to the questions of “how” or “by what process” or “by what means” or “on what basis.” Creation ex nihilo is, by human standards, very not-normal.
***There is a third option, which is that the universe does not necessitate human beings but rather wills human beings to exist. Will has the advantage of being free, rather than necessary, and so ‘the universe’ can be sufficient to produce humankind without having to do so. For some reason, naturalists don’t seem comfortable saying an infinite intelligence willed humanity into being. If I had to predict, I’d say they’re far more likely to take the first option, that human beings are necessary to the universe, and downplay this concession by saying everything else in the universe is necessary to it, too. But this merely elevates all creatures to a position of literal cosmic significance, rather than returning humanity to the desired(?) position of insignificance.
****The conclusion of the discourse, moved to this footnote so as not to confuse the reader, is as follows:
And this that they ask based upon essence and accident, the ReSheT already answers there, that accident is not its own existence and exists only with an essence. Thus, it is not true that when you find the essence without the accident, you will also find the accident without the essence.
An example of this question and answer in the ReSheT, as I understand them:
(Q) You say if I run into a composite and one of its parts I will know with certainty that the other parts exist apart from the composite, but that seems to imply if I see a brown cake and then the same cake colored white, that “being brown” exists in a pure state apart from any cake! And this seems absurd.
(A) “Being brown” is the sort of thing that exists only as a quality of another thing, but is not a thing in-and-of-itself; it is an accident, not an essence. Accidents are exceptions to the rule outlined by the Rambam and with which we have learned the persistence of the soul from the Midrash. They cannot, by definition, exist alone, apart from any composite. This is in contrast with speech or eggs or eating, which are substantial.
