“The world has not been hindered in its progress, but immensely aided in it, by England.”

"The Emotional Factor"Religion is based, I think, primarily and mainly upon fear.
Often paraphrased as "The Christian religion has been and still is the principal enemy of moral progress in the world."
1920s, Why I Am Not a Christian (1927)
Context: You find as you look around the world that every single bit of progress of humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or even mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world. I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world.

Report on Manufactures (1791)
Context: The Cotton Mill invented in England, within the last twenty years, is a signal illustration of the general proposition, which has been just advanced. In consequence of it, all the different processes for spinning Cotton are performed by means of Machines, which are put in motion by water, and attended chiefly by women and Children; and by a smaller number of persons, in the whole, than are requisite in the ordinary mode of spinning. And it is an advantage of great moment that the operations of this mill continue with convenience, during the night, as well as through the day. The prodigious affect of such a Machine is easily conceived. To this invention is to be attributed essentially the immense progress, which has been so suddenly made in Great Britain in the various fabrics of Cotton.

The Vocation of the Scholar (1794)
Context: Upon the progress of knowledge the whole progress of the human race is immediately dependent: he who retards that, hinders this also. And he who hinders this, —what character does he assume towards his age and posterity? Louder than with a thousand voices, by his actions he proclaims into the deafened ear of the world present and to come —"As long as I live at least, the men around me shall not become wiser or better; — for in their progress I too, notwithstanding all my efforts to the contrary, should be dragged forward in some direction; and this I detest I will not become more enlightened, — I will not become nobler. Darkness and perversion are my elements, and I will summon all my powers together that I may not be dislodged from them."

It is said with us to be unattainable. All communities divide themselves into the few and the many. The first are the rich and well born, the other the mass of the people. The voice of the people has been said to be the voice of God; and however generally this maxim has been quoted and believed, it is not true in fact. The people are turbulent and changing; they seldom judge or determine right. Give therefore to the first class a distinct, permanent share in the government. They will check the unsteadiness of the second, and as they cannot receive any advantage by a change, they therefore will ever maintain good government. Can a democratic assembly, who annually revolve in the mass of the people, be supposed steadily to pursue the public good?
