Famous quotes containing the words external and/or links:
“Truth in philosophy means that concept and external reality correspond.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“The conclusion suggested by these arguments might be called the paradox of theorizing. It asserts that if the terms and the general principles of a scientific theory serve their purpose, i. e., if they establish the definite connections among observable phenomena, then they can be dispensed with since any chain of laws and interpretive statements establishing such a connection should then be replaceable by a law which directly links observational antecedents to observational consequents.”
—C.G. (Carl Gustav)
