In 1996, the complexity theorist John Casti described the behavior of systems like the global economy or the weather as being governed by "investment indivisibilities" and "feedback loops." He argued that such systems are not just complicated, but complex — meaning they cannot be understood by simply breaking them down into their constituent parts. Instead, they exhibit emergent properties that are greater than the sum of their parts. One of the key characteristics of complex systems is their susceptibility to "tail events" — rare, high-impact events that lie at the extreme ends of a probability distribution. Casti pointed out that in a normal distribution, these events are so rare they can be safely ignored. However, in complex systems, the distribution of events often follows a "power law," where tail events are much more frequent than a normal distribution would predict.

Furthermore, Casti argued that the occurrence of a first-order tail event often changes the underlying structure of the system, making subsequent tail events more likely. This is what he termed a "cascade effect." For example, a major stock market crash doesn't just happen in isolation; it alters the psychology of investors and the liquidity of the market, creating a new environment where further crashes are more probable. This inherent instability makes long-term prediction in complex systems nearly impossible, as any model based on past data is rendered obsolete the moment a major tail event occurs. Consequently, the only way to manage such systems is through resilience and adaptation, rather than through attempts at precise control or prediction.

The aesthetic of electronic music has often been challenged by those who view it as "inhuman" or "mechanical." Critics argue that because the sound is generated by oscillators and processed by circuits, it lacks the expressive nuance of acoustic instruments played by human hands. However, this view fails to account for the unique "language of forms" that electronic music employs. As the composer Karlheinz Stockhausen noted, electronic music is not an attempt to imitate acoustic instruments, but a quest for entirely new sonic territories. The very lack of acoustic antecedents is what makes electronic sound sui generis — of its own kind.

The "communication problem" that listeners often face when first encountering electronic music arises from its unfamiliar structural procedures. In traditional music, we are accustomed to melody, harmony, and rhythm as the primary vehicles of expression. Electronic music often replaces these with textures, timbres, and spatial distributions of sound. When a listener understands that the composer is manipulating the very internal structure of the sound itself — rather than just arranging pre-existing notes — the music begins to communicate in a powerful, albeit different, way. It requires a shift in perception, moving away from the nineteenth-century ideal of music as a vehicle for emotional storytelling and toward a more modern conception of music as a speculation in terms of sound and time.

The debate over whether income inequality drives or hinders economic growth remains one of the most contentious issues in modern economics. Proponents of a positive link often point to three main arguments. First, "investment indivisibilities": in economies with underdeveloped capital markets, concentrated wealth is necessary to fund large-scale projects that require significant upfront investment. Second, the "incentive or moral hazard argument": inequality provides the necessary motivation for individuals to work harder and take risks, as the rewards for success are significantly higher. Third, corporate governance: concentrated ownership can lead to better monitoring of management, reducing free-rider problems associated with dispersed ownership.

However, critics argue that these arguments are often overstated or only applicable in specific, limited contexts. They point out that extreme inequality can lead to social instability, underinvestment in human capital, and the entrenchment of rent-seeking elites who use their power to stifle competition. Furthermore, the "democratization" of finance and the development of sophisticated stock markets have made the "investment indivisibilities" argument increasingly obsolete in mature economies. In such settings, wealth concentration may actually be harmful, as it limits the pool of potential investors and can lead to market distortions. The primary function of the case for inequality-driven growth is thus to show that while it may aid growth in certain underdeveloped settings, it is far from a universal law.

The legal history of criminal responsibility in the nineteenth century is a fascinating study in the "democratization" of the law. Prior to this period, the defense of insanity was rarely used and even more rarely successful. The legal standard for insanity was the "wild beast test," which required the defendant to be as totally deprived of their understanding and memory as a wild beast. However, as the century progressed, the influence of "alienists" — early psychiatrists — began to reshape the courts' understanding of mental states. They argued that a defendant could appear perfectly rational while still suffering from a "moral insanity" that rendered them incapable of controlling their actions.

This shift in understanding led to the establishment of the M'Naghten Rules in 1843, which remains the basis for the insanity defense in many jurisdictions today. However, the application of these rules was often inconsistent and influenced by the social identity of the defendant. Alienists, who were typically middle-class, white, professional men, were more likely to find empathy for defendants who shared their background. When a defendant struck officials as unlike themselves — whether by dint of disease, gender, confession (religion), or race — the precariousness of judgments about mental state was exposed. The "borders of criminal responsibility" were thus not just legal lines, but social ones, reflecting the biases and anxieties of the era.
