Jacques Derrida’s deconstruction is a critical strategy that challenges the belief that words and concepts possess stable meanings. Although its principles are simple and widely applicable, deconstruction is formidable because it threatens the very stability of meaning itself. This essay argues that through différance, inversion and subversion, Derrida shows that philosophy’s foundational concepts are unstable. By applying deconstruction to reason itself, the essay challenges reason’s claim to be philosophy’s secure foundation of truth and meaning.
Derrida utilises the term différance to combine the meanings of the two words difference and deferral into a single term. When applied to specific words, différance exposes the unstable condition of the relationship between words and their meanings. To demonstrate this, consider the word “house”. Rather than being self-contained within the word, the meaning of “house” emerges through its difference from related words such as “shed”, “apartment”, “tent”, or “building”. However, those related words are not fixed either. They are themselves understood through their relations to further words. Derrida refers to this condition as deferral: the process by which meaning passes from one word to another, and from there to another again, ad infinitum, without ever becoming fully present in any single term (Derrida 1996, 441-49).
Inversion and subversion further destabilise meaning by exposing the hierarchies within binary oppositions where one concept is privileged and its opposite subordinated. For example, in the binary opposition of strong and weak, “strong” is often treated as primary because it appears, at first glance, to be preferable. Inversion involves reversing a hierarchical opposition by temporarily privileging the term that has traditionally subordinated. This exposes the dependence of the primary term on the term it excludes. Subversion then destabilises the opposition itself by showing that each term depends on the other for its meaning (Lawlor 2023, sec. 5). Using the term “reason” as an example, reason can be positioned in a binary with a range of other terms which it appears to oppose: reason / madness, reason / emotion and reason / faith – to list just a few. In these three examples, reason is often understood to be hierarchically superior. Through inversion and subversion, these hierarchies are first reversed and then destabilised, showing that reason cannot be cleanly separated from the terms it excludes.
In the opposition of reason/madness, by temporarily privileging madness, it is revealed that reason only defines itself as sane, coherent, and logical by excluding madness as irrational, incoherent, and illogical. This destabilises the opposition by showing that madness is not external to reason, but part of the boundary through which reason defines itself. The inversion of the reason / emotion opposition reveals that reason is not a pure and self-contained concept, but dependent on emotion for its direction and value. Reason can be understood as an individual’s capacity to think, judge and form conclusions through logic and rigor. In order for an individual to utilise their faculty of reason, they must be sufficiently motivated to do so. Without motivation, there is no cause to utilise reason. Motivation, then, is prior to reason. Since motivation involves affective concern for some end or value, reason depends on emotion to give it direction. Emotion therefore is not reason’s inferior opposite but a condition for its possibility.
Finally, in the reason / faith opposition, reason might be regarded as superior because it is logical, rigorous, evidence-based, and impartial. Faith, by contrast, is treated as inferior because it entails belief in things that cannot be fully demonstrated through reason or empirical evidence. When this opposition is inverted, however, reason can be presented as dependent on faith-like trust. Valid reasoning frequently leads philosophers to simultaneously incompatible conclusions, yet philosophers continue to treat reason as the proper judge of truth. For instance, one line of reasoning can conclude that the Universe must have a single point of origin, whereas another robust line of reasoning concludes the Universe is infinite. If valid reason can lead to incompatible conclusions, then it does not follow that reason itself contains innate authority. This reveals a circular dependence: reason cannot justify its own authority without first assuming that reason is authoritative. Thus, reason’s authority depends on a faith-like commitment.
This deconstruction of the meaning of reason can result in multiple conclusions, ranging from moderate to radical. A moderate conclusion is simply pointing out how reason appears dependent on the very terms it traditionally subordinates. A more ambitious conclusion would be to reject reason’s privileged status entirely: if reason depends on the very terms it subordinates, then its claim to superiority as logical, rigorous, evidence-based, and impartial is no longer secure.
Given that deconstruction can be applied to virtually all concepts involving a binary such as truth / error, and good / evil, deconstruction threatens to undermine the foundations which philosophy depends on. However, such a radical conclusion is open to the criticism that deconstruction moves too quickly from the instability of particular meanings to much larger claims about rhetoric and metaphysics without sufficient warrant (Culler 1982, 246). By pointing out that the concept of reason has an unstable boundary with its opposites, the traditional meaning of the term reason dissolves, but this alone does not automatically necessitate that reason itself collapses. It remains plausible that reason has unstable conceptual boundaries without losing its usefulness as a tool for thought. Suppose this is correct, and reason survives as a valuable mode of thinking in spite of its conceptual identity breaking down. Reason then takes the form of an abstract phenomena that resists a clear definition and an understanding of exactly what its capabilities and limits are. In this state, reason no longer presents with the power and potency of its traditional understanding. Without its former prestige, it remains difficult to hold reason as the single secure foundation from which philosophy grounds truth and meaning.
This aligns with the broader critique of what Derrida calls logocentrism: the privileging of reason, logic, speech and rational ordering in western philosophy. If logos cannot be fully stabilised, then philosophy can no longer claim that reason gives it direct access to secure truth and meaning (Reynolds n.d., sec. 2a). Logocentrism prevails throughout modern academia, but it also presents as a common popular ideal throughout society today with intuition, relating and functions involving emotion and feeling are subordinated to reason and rationality. Logos is undoubtedly useful, but once deconstruction undermines its authority, there is no reason why it should be exalted to the heights in which it is. This realisation may be catastrophic to philosophy, but for society in general, the deflation of logos and the liberation of other functions such as feeling may lead to a more balanced mode of understanding ourselves and the world.
