Thomas More was a statesman, theologian, humanist, friend of Erasmus of Rotterdam. He opposed Henry VIII's separation from the Catholic Church. After refusing to take an oath acknowledging the King as Supreme Head of the Church of England, More was convicted of treason and executed in 1535.
His book "Utopia" was first printed in 1516, well before the industrial revolution.

The book describes the fictitious island state Utopia, which is organized as a pre-industrial communist society. (That Thomas More was a Catholic scholar corroborates that there is a Christian base for communism.)
The Utopians' justifications for conquest of land are similar to the pretexts given for the upcoming European colonialism, the seizure of land of American Indians and Hitler's invasion of Eastern Europe.
The Utopians share some of their main stream ideas with Epicurus' philosophy:
"They seem, indeed, more inclinable to that opinion that places, if not the whole, yet the chief part, of a man’s happiness in pleasure;"
“Thus, upon an inquiry into the whole matter, they reckon that all our actions, and even all our virtues, terminate in pleasure, as in our chief end and greatest happiness; and they call every motion or state, either of body or mind, in which Nature teaches us to delight, a pleasure."
“They reckon up several sorts of pleasures, which they call true ones; some belong to the body, and others to the mind."
"... they almost universally agree that health is the greatest of all bodily pleasures; and that as there is a pain in sickness which is as opposite in its nature to pleasure as sickness itself is to health, so they hold that health is accompanied with pleasure."
Reasons are given that health is not just a neutral state but a pleasure:
E.g. "What is the pleasure of eating, but that a man’s health, which had been weakened, does, with the assistance of food, drive away hunger, and so recruiting itself, recovers its former vigour? And being thus refreshed it finds a pleasure in that conflict; and if the conflict is pleasure, the victory must yet breed a greater pleasure, except we fancy that it becomes stupid as soon as it has obtained that which it pursued, and so neither knows nor rejoices in its own welfare."
Other main stream ideas of the Utopians are opposite to Epicurus' philosophy:
“These are their religious principles:—That the soul of man is immortal, and that God of His goodness has designed that it should be happy; and that He has, therefore, appointed rewards for good and virtuous actions, and punishments for vice, to be distributed after this life."
Regarding those who do not believe in an immortal soul and rewards and punishments in the afterlife, the Utopians "never raise any that hold these maxims, either to honours or offices, nor employ them in any public trust, but despise them, as men of base and sordid minds. Yet they do not punish them, because they lay this down as a maxim, that a man cannot make himself believe anything he pleases; nor do they drive any to dissemble their thoughts by threatenings, so that men are not tempted to lie or disguise their opinions; which being a sort of fraud, is abhorred by the Utopians: they take care indeed to prevent their disputing in defence of these opinions, especially before the common people: but they suffer, and even encourage them to dispute concerning them in private with their priest, and other grave men, being confident that they will be cured of those mad opinions by having reason laid before them."
