No less than Newton, Hooke believed in the existence of principles that would unify the whole of creation.
The following sections make no attempt to explore all aspects and interconnections of complex material systems, but they highlight a few ideas which pervade the field and which indicate the existence of principles that find little place in the fundamental laws yet are the outcome of their operation.
It was not primarily a debate over the existence of principles of beauty, a matter over which theorists of taste might disagree.
Indeed, according to some scholars, this is the only place to track down a demonstration of the existence of the Principle in the Metaphysics of the Book of the Healing (Bertolacci 2007).
Finally, I am indebted to Jerzy Hanusek for pointing out that Existence of Extensions principle can be derived more simply in Frege's system directly from the classical logic of identity.
(A More Complex Example) But now the Existence of Extensions principle follows by universal generalization on the concept variable F. Thus, simply by adding a term-forming operator such as ε to classical logic with identity, it is provable that every concept gets correlated with an extension.
In conclusions, our study on CNF and FSGS tubular cells during cystogenesis revealed serious disturbances of cells proliferation, apoptosis and primary cilia formation, implying existence of general principle of kidney cystogenesis, independently of its cause.
They held the eternal existence of moral principles and of truth and that the human mind is equipped with the principles of reason and morality.
Hard-nosed Bayesians may insist that whatever reasoning goes on in the categorical mode must eventually be justifiable in Bayesian terms, but this presupposes the existence of bridge principles connecting the epistemology of belief with the epistemology of degrees of belief and, as mentioned, whether such principles exist is presently unclear.
This alteration probably dates back at least to the 4th century bce, for Aristotle said in the Peri philosophias ("On Philosophy") that the Magi preached the existence of two principles, Oromasdes and Areimanios.
