You even changed some words to make them fit into your distorted, dishonest version.
Again, this is what you wrote:
A crowd of difficulties…occur…Some of them are so serious that to this day I can hardly reflect on them without being in some degree staggered…
And this is the true quote that you chopped up and altered:
Long before having arrived at this part of my work, a crowd of difficulties will have occurred to the reader. Some of them are so grave that to this day I can never reflect on them without being staggered; but, to the best of my judgment, the greater number are only apparent, and those that are real are not, I think, fatal to my theory.
