As I sit here typing on my computer, it’s easy to get
overwhelmed by the wealth of knowledge and benefits science has brought
us. In fact, it’s so easy that we have
to a great extent forgotten the appalling depths of our ignorance.
How can I say that?
Very simple: the quantity of unknowns in the universe is by definition
unknowable. This gives us Layne’s First
Law of General Ignorance: We don’t know
how much we don’t know. If we know,
then, that the extent of our ignorance is unknowable, we know that at least one
thing is unknowable. But we don’t know
if there’s anything else that Man cannot comprehend or will not be able to
comprehend at some future date.
Therefore, the corollary to the First Law: We don’t know how much we can’t
know.
Got a headache yet?
Most thought systems have to start with at least some
assumptions that neither need nor admit of proof. For instance, you can’t get anywhere in plane
geometry if you don’t accept that “a line is the shortest distance between two
points”, or in algebra if a2 =
b2 + c2 is merely an opinion. Likewise, reason has a fundamental assumption
that “a thing cannot both be and not-be at the same time and in the same
manner”.
Why can’t we take atheism as self-evidential? This seems to be the answer the New Atheist
prefers, given that philosophers since Socrates have known that it’s impossible
to prove that something does not
exist. In law, we take it as a necessary
presumption of justice that a person accused of a crime is innocent until
proven guilty. Are there not situations
in which we can safely presume that a theory is false until proven true?
