To begin with clear and self-evident principles, to advance by timorous and sure steps, to review frequently our conclusions, and examine accurately … - David Hume

It is seldom that liberty of any kind is lost all at once.

Nothing is more usual and more natural for those, who pretend to discover anything new to the world in philosophy and the sciences, than to insinuate the praises of their own systems, by decrying all those, which have been advanced before them. And indeed were they content with lamenting that ignorance, which we still lie under in the most important questions, that can come before the tribunal of human reason, there are few, who have an acquaintance with the sciences, that would not readily agree with them. 'Tis easy for one of judgment and learning, to perceive the weak foundation even of those systems, which have obtained the greatest credit, and have carried their pretensions highest to accurate and profound reasoning. Principles taken upon trust, consequences lamely deduced from them, want of coherence in the parts, and of evidence in the whole, these are every where to be met with in the systems of the most eminent philosophers, and seem to have drawn disgrace upon philosophy itself.

Nay, if we should suppose, what seldom happens, that a popular religion were found, in which it was expressly declared that nothing but morality could gain the divine favor; if an order of priests were instituted to inculcate this opinion in daily sermons and with all the arts of persuasion; yet so inveterate are the people's prejudices, that, for want of some other superstition, they would make the very attendance on these sermons the essentials of religion, rather than place them in virtue and good morals.
