“My sister and I, you will recollect, were twins, and you know how subtle are the links which bind two souls which are so closely allied.” —Sir Arthur Conan Doyle (1859–1930)
“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)
“Nothing is more indispensable to true religiosity than a mediator that links us with divinity.” —Novalis [Friedrich Von Hardenberg] (1772–1801)
