The Time Machine
How we cite our quotes:
I saw mankind housed in splendid shelters, gloriously clothed, and as yet I had found them engaged in no toil. There were no signs of struggle, neither social nor economical struggle. The shop, the advertisement, traffic, all that commerce which constitutes the body of our world, was gone. (4.27)
With his interest in social class and economic problems, the Time Traveller notes their absence as a major change. But there are still similarities: people still need shelter and clothes (so it must not be that warm), and it still rains.
Humanity had been strong, energetic, and intelligent, and had used all its abundant vitality to alter the conditions under which it lived. And now came the reaction of the altered conditions. (4.29)
In The Time Machine, Time can't be turned off – change still goes on, even if you don't want it to. People made deliberate changes to the world and got very comfortable – and now they are evolving in response to the changes they made.
The Upper-world people might once have been the favoured aristocracy, and the Morlocks their mechanical servants: but that had long since passed away. The two species that had resulted from the evolution of man were sliding down towards, or had already arrived at, an altogether new relationship. (7.2)
While the Time Traveller gets to see snapshots of the world at certain points of time, he recognizes that time is an ongoing thing, and that change will continue to occur.
