Regarding skepticism, I didn't say that skepticism was a new idea, I said that the idea that science can replace philosophy is a new idea. The kind of skepticism you're talking about is actually incompatible with modern science, so it can hardly be taken as an example of a scientific world view. After all, one pretty clear example of recent progress in philosophy is the demonstration that scientific theories are not reducible to statements about actual and hypothetical experiences or "appearences" (i.e., the failure of logical positivism).
"By suspending judgment, by confining oneself to phenomena or objects as they appear, and by asserting nothing definite as to how they really are, one can escape the perplexities of life and attain an imperturbable peace of mind."
It's the "confining oneself to phenomena or objects as they appear" where the break from philosophy occurs.
From the scientific standpoint you ignore the concept of life after death and other "perplexities of life" because it's not knowable. A true scientist builds models on what phenomena he sees and lays no clams one what he can't. Now you might question how that works with a paleontologist, but confining oneself to phenomena means a he thinks it's reasonable to look for patterns based on what your eyes tell you because they are not deceiving you even if they are not a window to deep truth. A paleontologist does not argue with the fact god could have created the world ten seconds ago, rather he argues "excluding unknowable things" this is the patterns I see. But, a philosopher sees no lines of inquiry outside of his purview and still attacks the unknowable questions such as life after death or the invisible god who does nothing.
PS: A better example from that time would be how a water clock behaves after you leave the room, if it displayed the correct time when you get back may have gotten up and danced about the room before you got back and hidden that from you but if that's the case it's an unknowable truth best ignored for visible phenomena.
