For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or… - David Hume

But though all the general rules of art are founded only on experience and on the observation of the common sentiments of human nature, we must not imagine, that, on every occasion, the feelings of men will be conformable to these rules.

It is indeed a mortifying reflection to those who are actuated by the love of fame, so justly denominated the last infirmity of noble minds, that the wisest legislator and most exalted genius that ever reformed or enlightened the world can never expect such tributes of praise as are lavished on the memory of pretended saints, whose whole conduct was probably to the last degree odious or contemptible, and whose industry was entirely directed to the pursuit of objects pernicious to mankind. It is only a conqueror, a personage no less entitled to our hatred, who can pretend to the attainment of equal renown and glory.

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.
