The most ingenious men are now agreed, that [universities] are only nurseries of prejudice, corruption, barbarism, and pedantry.

Casting an eye on the education of children, from whence I can make a judgment of my own, I observe they are instructed in religious matters before they can reason about them, and consequently that all such instruction is nothing else but filling the tender mind of a child with prejudices.

From my own being, and from the dependency I find in myself and my ideas, I do, by an act of reason, necessarily infer the existence of a God, and of all created things in the mind of God.

I had rather be an oyster than a man, the most stupid and senseless of animals.

Whenever I attempt to frame a simple idea of time, abstracted from the succession of ideas in my mind, which flows uniformly, and is participated by all beings, I am lost and embrangled in inextricable difficulties.

But, say you, surely there is nothing easier than for me to imagine trees, for instance, in a park [. . .] and nobody by to perceive them. [...] The objects of sense exist only when they are perceived; the trees therefore are in the garden [. . .] no longer than while there is somebody by to perceive them.

I imagine that thinking is the great desideratum of the present age; and the cause of whatever is done amiss may justly be reckoned the general neglect of education in those who need it most, the people of fashion. What can be expected where those who have the most influence have the least sense, and those who are sure to be followed set the worst examples?
