We are on the road to producing a race of men too mentally modest to b — Skepticism

"They know their profession, but they ignore anything unconnected with their profession. So, to protect their self-esteem, they call everything into question, criticize right and left; seem skeptical but are actually gullible, and drown their minds in interminable discussions. Almost all of them adopt convenient social, literary, or political prejudices so as to dispense with having to form an opinion of their own, just as they place their conscience in the shelter of common law, or of the commercial court. Having left home early in order to become remarkable men, they become mediocre, and crawl along the heights of society. Accordingly, their faces present us with this sour pallor; these false complexions, these dull, lined eyes, these talkative and sensual mouths where the observer recognizes the symptoms of the degeneration of thought and its turning round and round in the dull circle of specialization that kills the generative faculties of the brain, the gift of seeing the big picture, of generalizing and deducing."

"Even if my philosophy does not extend to discovering anything new, it does nevertheless possess the courage to regard as questionable what has long been thought true."

"During the nine subsequent years, I did nothing but roam from one place to another, desirous of being a spectator rather than an actor in the plays exhibited on the theatre of the world; and, as I made it my business in each matter to reflect particularly upon what might fairly be doubted and prove a source of error, I gradually rooted out from my mind all the errors which had hitherto crept into it. Not that in this I imitated the Sceptics who doubt only that they may doubt, and seek nothing beyond uncertainty itself."

"This conceit which understands how to belittle every truth, in order to turn back into itself and gloat over its own understanding, which knows how to dissolve every thought and always find the same barren Ego instead of any content—this is a satisfaction which we must leave to itself."

"By the conversion of opinion held on authority into opinion held out of personal conviction, the content of what is held is not necessarily altered, and truth has not thereby taken the place of error. If we stick to a system of opinion and prejudice resting on the authority of others, or upon personal conviction, the one differs from the other merely in the conceit which animates the latter. Scepticism, directed to the whole compass of phenomenal consciousness, on the contrary, makes mind for the first time qualified to test what truth is; since it brings about a despair regarding what are called natural views, thoughts, and opinions, which it is matter of indifference to call personal or belonging to others, and with which the consciousness, that proceeds straight away to criticize and test, is still filled and hampered, thus being, as a matter of fact, incapable of what it wants to undertake."

"The doctrine of those who have denied that certainty could be attained at all, has some agreement with my way of proceeding at the first setting out; but they end in being infinitely separated and opposed. For the holders of that doctrine assert simply that nothing can be known; I also assert that not much can be known in nature by the way which is now in use. But then they go on to destroy the authority of the senses and understanding; whereas I proceed to devise helps for the same."
