The Encyclopedia presents a contemporary version of the ancient encyclopedic ideal of Aristotle, the Scholastics, Leibniz, the Encyclopedists, and Co… - Charles W. Morris

What of the term 'meaning'? In the preceding discussion the term 'meaning' has been deliberately avoided. In general it is well to avoid this term in discussions of signs; theoretically, it can be dispensed with entirely and should not be incorporated into the language of semiotic. But since the term has had such a notorious history, and since in its consideration certain important implications of the present account can be made clear, the present section is devoted to its discussion.

Men are the dominant sign-using animals. Animals other than man do, of course, respond to certain things as signs of something else, but such signs do not attain the complexity and elaboration which is found in human speech, writing, art, testing devices, medical diagnosis, and signaling instruments. Science and signs are inseparably interconnected, since science both presents men with more reliable signs and embodies its results is systems of signs. Human civilization is dependent upon signs and systems of signs, and the human mind is inseparable from the functioning of signs - if indeed mentality is not to be identified with such functioning.

Semiotic itself neither rests on nor necessarily implies a particular philosophy. A science of signs no more decides between an 'empirical' and a 'non-empirical' philosophy than it decides between a 'naturalistic' and a 'supernaturalistic' religion. In itself it cannot force one to believe only scientifically verified statements, nor to use only scientific discourse, nor to form one's appraisals and prescriptions in the light of science. It will nevertheless have a profound influence on the course of philosophy, since it deals with topics peculiarly relevant to philosophic systematization... In this sense, the philosophy of the future will be semiotically oriented. But the nature of this influence will not always be the same, and will depend upon the role which given individuals and societies assign to scientific knowledge.
