Even before he wrote the Travels, Swift opposed excessive pride in reason. In his ironical Argument Against Abolishing Christianity, he makes plain what he considers to be the consequences of depending on reason, rather than upon faith and revelation. Disbelief, he said, is the consequence of presumptuous pride in reasoning, and immorality is the consequence of disbelief. Swift believed that religion holds moral society together. A person who does not believe in God by faith and revelation is in danger of disbelieving in morality.
To Swift, rationalism leads to Deism, Deism to atheism, and atheism to immorality. Where people worship reason, they abandon tradition and common sense. Both tradition and common sense tell humankind that murder, whoring, and drunkenness, for example, are immoral. Yet, if one depends on reason for morality, that person can find no proof that one should not drink, whore, or murder. Thus, reasonably, is one not free to do these things? Swift believed that will, rather than reason, was far too often the master.
Alexander Pope agreed with the position that Swift took. In his Essay on Man, he states that people cannot perceive accurately. Our axioms are usually contradictory, and our rational systems of living in a society are meaninglessly abstract. People, he insists, are thoroughly filled with self-love and pride; they are incapable of being rational — that is, objective. Swift would certainly concur.
In Book III, Laputan systematizing is exaggerated, but Swift's point is clear and concrete: Such systematizing is a manifestation of proud rationalism. The Laputans think so abstractly that they have lost their hold on common sense. They are so absorbed in their abstractions that they serve food in geometric and musical shapes. Everything is relegated to abstract thought, and the result is mass delusion and chaos. The Laputans do not produce anything useful; their clothes do not fit, and their houses are not constructed correctly. These people think — but only for abstract thinking's sake; they do not consider ends.
