Introduction
Two classes of people inhabit this world: some perceive nature as it ought to be, and those who perceive it as it is. The former portends the world to be a better place. They are optimistic of a better life based on hope, as Elman & Jensen (2014) assert. This class of philosopher is called the idealist and tends to romanticise their perception of nature. The latter are normally called the realists. They are diametrically divergent from the romanticism associated with the idealists (Binkley, 2009). Realists, sometimes called the cynics, offer cold and calculating illustrations of the way the world operates. Their view of reality is considered pessimistic. Actors in the world stage, according to the realist world view, seek to achieve selfish interests (Elman & Jensen, 2014).
The theory of realism, which is divided into two sub-groups, has gone through serious changes since it was developed. Despite this, its subclasses have maintained their uniqueness. These subclasses are the classical realism subclass and the structural realism, also referred to as neo-realism (Binkley, 2009). There are marked differences between these two types of realisms, albeit slight. These differences are illustrated below.
Fundamental Differences
Initially, realism originated in opposition to a moralistic as well as idealistic understanding of how the components that form life relate. Classical idealists explain that human nature is not value-free. Instead, they assert that the investigation of domestic and international political exercise and an all-inclusive study of human nature constitute classical realism (Elman & Jensen, 2014). By having a multifaceted analysis of political exercise into the idea of realism, classical realism grows into an unoperationalizable idea, as viewed by scholars of structural realism.
Structural realists see realism as not a scientific discipline, at least not scientific enough. They assert that true realism is built on a system made of a structure as well as interacting units. They argue that the fundamental structure is the main feature of realism. In defining the structure, Structural aver that features of the units that make up the structure have to be omitted so as to cultivate a strictly scientific structure (Realism, 2012). According to neo-realists, only the structure brings out a pure and secure outset for the understanding of interstate relations. They draw equivalents to economic research, in which an ongoing examination of specific companies or specific transactions is a theory founded on the well-known concept of the economic market, and rational markets (Elman & Jensen, 2014). Proponents of this notion, such as Walt, are familiar with the fact that the economic man does not exist in real life. He is made to exist theoretically to develop an operationalisable theory of realism, which is only useful in determining general life expectations.
Clearly, classical realism does not support the idea of a scientific theory that is entrenched in assumptions. By making these assumptions as significant as structural realism, the entire substance of neo-realism turns is based on stipulation rather than on an unending argument, as it ought to be (Keohane, 2014). Thus, the nature of human beings and structural considerations are foundations of classical realism, while structural realism assumes that the nature of human beings is based on broad assumptions equivalent to the notion of the economic man, yet of only gives attention to the structure.
Classical realists believe that the way a man feels, thinks, and acts is not rational as neo-realists see it. A thorough examination of constant human behaviour discloses instincts of honour and profiteering that exceed the structurally inspired uncertainties that structural realism is founded on. Therefore, seen against real-life phenomena such as international relations, realism is assumed to be a method that can be directed to master peace in the sense of a universal empire, a scholar of classical realism concludes. Neo-realism, on the other hand, favours a realistically restricted interpretation of national interests and a sensible appreciation of common good for all international relations, which is a device through which conflict is minimised. This nurtures global peace. Further, sustained achievements are perceived as more important than relative gains (Realism, 2012). This belief holds rationalistic assumptions about the nature of humanity, something that classical realism experts dismiss as intangible and theoretical.
Interestingly, structural realism, while focusing only on the structure itself of life, overlooks the structural components acting within the larger structure, and is perceived as the science of peace as well as a technology meant for a just and peaceful universe. Undoubtedly, neo-realism eliminates moral considerations in the design of the Neo-realism theory. Yet, the results are morally positive. This ought to be equivalent to economic markets in which economic players act towards their own self-interest in an unrestrictive environment (Carlson & Owens, 2003). Yet, the outcome is usually favourable to all and sundry. Definitely, one can argue that the theories of economic man stated elsewhere in this paper are very operationalizable. However, conversely, it is ot worth much.
Regarding conflicts, even though the two schools of realistic thought come to an agreement on the unavoidability of conflict, they differ on the causes of the conflicts. Classical realists propose the theory that humanity is flawed, wicked, and imperfect. This is the core cause of conflicts. On the other hand, neo-realists see conflict as a more systemic. They discard the subjective view of the classical realists (Ferguson & Mansbach, 2011). Waltz emphasizes this and argues that given that human nature originates conflict, the same nature can design peace. Structural realists assert the notion that the international system, here termed as disordered and anarchical, leads to competition for power because of the absence of a central authority figure. Suffice it to state that the United Nations undoubtedly cannot be considered a Goliath force that successfully supervises and commands all global peace efforts (Carlson & Owens, 2003). Therefore, countries are typically left to rely on their own internal devices in their efforts to assert power and authority on the global stage of international relations (Ferguson & Mansbach, 2011).
To clearly express how the universe operates, neo-realists seek to generate a more systematic and unprejudiced method within international relations. They derive their ideals from traditional classical ideas and build on them by including empiricism. Neorealist philosophers deduce global politics as a constituting a delicate scheme of balance. They aver that regardless of the prevailing style of management, each nation-state is regarded as the foundational component in the neo-realistic theory (Rahman, Primiero & Marion, 2012). All countries have common needs that include, but are not limited to, security, food, energy, and infrastructure. However, world nations experience deficits in the ability to attain these requirements. Such deficits are referred to as distribution of capabilities, and these deficits limit collaboration amongst nations since each country worries about any relative gains accrued by competition, which impinges on the interests of individual states (Carlson & Owens, 2003).
Conclusion
To conclude, while many critics argue that there is fundamentally no difference between structural and classical theories of realism, according to Rahman, Primiero, & Marion (2012), it appears that there is a major difference between these two subclasses of realism. The major difference appears to be the extent to which the two sub-theories are grounded in scientific principles. Opponents of structural realism argue that, in a similar fashion to the economic theory, the realist theory takes itself away from actual reality the more scientific it claims to be. While this notion is clearly neither right nor wrong, it appears that the more operational it is, the less realist philosophers can define future advancements. The opposite is also true. The less scientific realism is the more it becomes attached and relatable to real life.
