It is clear even in the opening chapters of the novel, that the Time Traveler shares many of Wells own biases and belief systems. Though he believes that the Eloi have devolved due to the fact that they no longer need to work or improve their minds, the Time Traveler believes that this society is better than the one he came from where the poor were routinely mistreated and often malnourished. In many ways, the Time Traveler is the ultimate egalitarian: he believes that an Eloi society where the community works together to find its food and to live as equals is superior to his own society.
It is not until the Traveler becomes aware of the presence of the Morlocks that he begins to question his initial impression. The fact that the Morlocks have become cannibalistic, Eloi-herders as a way of life is incredible depressing to the Traveler and he sets about to document these changes. Wells writes eventually that the Traveler is wrong in his theory about how the Morlocks and the Eloi come to be, but never discusses what the real cause of the evolution might be.
From a philosophical standpoint, Wells development of the Eloi and Morlocks in his story is a remarkable commentary on his observations regarding the nature of man and how society might evolve. It is clear that in the Travelers initial opinion, the Eloi have developed from the upper class, from those who were too soft for manual labor and to enamored of recreational pursuits to challenge their minds. Likewise, the Morlocks are clearly supposed to have developed from the underclass and have resorted to violence and death as their way of life, never evolving to the point of problem solving or higher thought. In these most basic descriptions, Wells reveals his own bias towards the class warfare of Victorian England.
Indeed, the Morlocks propensity for flesh-eating might well have developed out of the satirical writings of Jonathon Swift and his A Modest Proposal. Though in Swifts essay it is the rich who eat the poor as a form of population control, his commentary on the classes is very clearly echoed in The Time Machine. Both men argue effectively that class differences in the British Isles will likely lead to one class eating the other. By the subtle change from Swifts Proposal to Wells Morlocks, we find that Wells believes it is likely the working class that will become cannabalistic and that the upper class has no redeeming qualities other than the ability to stuff their faces.
Another philosophical issue facing the Time Traveler is the impact his travel will have on the world around him. This issue is central to the most recent film adaptation of the movie. In it, the Traveler attempts repeatedly to change the course of time to save his ill-fated fianc from certain death. In both the film and the novel, the Time Traveler is forced to eventually face that he is unable to change the natural progression of time.
The most interesting question here is whether he should have attempted to change time in the first place. Having seen the existence of the Eloi and the Morlocks and the eventual destruction of the planet, does the Traveler have any right to unwind, rewind or otherwise twist the fabric of time? This question is largely unresolved in the novel, as the Traveler simply discovers that if he changes one event in the past, other events adapt to end with the same conclusion.
The other question that this demands an answer to is the theory of time itself and of predetermination. If the Traveler is unable to change destiny by changing a specific event and if time adapts so that what is supposed to happen does, in one fashion or another, is there truly any conception of self-determination or is everything predestined. In his novel, Wells makes an effective argument for the concept that things happen as they are ordained to happen and mans impact on them is infinitesimal. He argues through the repeated deaths of the Time Travelers fianc that fate is fate and cannot be changed.
The joy of Wells novel is that on the surface it is simply a fantastical voyage into a future that might be, but that once one begins to scratch the surface, he finds a commentary on social justice, industrialization and even religion, as some religions argue that man is pre-destined to live his life in a certain manner.
By never resolving the issues within the book, Wells allows the reader to determine for themselves whether they believe in predetermination or if they believe the future can be changed. He allows the reader to make his own judgments regarding the battle between nature and industrialization and he allows the reader to decide how the battle between the classes will end. The novel allows the reader to take as much or as little from it as they desire and as such it is a classic of English literature.
