Charles Sanders Peirce
Charles Sanders Peircewas an American philosopher, logician, mathematician, and scientist who is sometimes known as "the father of pragmatism". He was educated as a chemist and employed as a scientist for 30 years. Today he is appreciated largely for his contributions to logic, mathematics, philosophy, scientific methodology, and semiotics, and for his founding of pragmatism...

character mind littles
When anything is present to the mind, what is the very first and simplest character to be noted in it, in every case, no matter how little elevated the object may be? Certainly, it is its presentness .
taken may pairs
A pair of statements may be taken conjunctively or disjunctively; for example, "It lightens and it thunders ," is conjunctive, "It lightens or it thunders" is disjunctive. Each such individual act of connecting a pair of statements is a new monad for the mathematician .
mean thinking objects
By an object, I mean anything that we can think, i.e. anything we can talk about.
science drawing study
The one [the logician] studies the science of drawing conclusions, the other [the mathematician] the science which draws necessary conclusions.
wine men psychology
It has never been in my power to study anything, mathematics, ethics, metaphysics, gravitation, thermodynamics, optics, chemistry, comparative anatomy, astronomy, psychology, phonetics, economics, the history of science, whist, men and women, wine, metrology, except as a study of semeiotic .
determined latter former
I define a Sign as anything which is so determined by something else, called its Object, and so determines an effect upon a person, which effect I call its Interpretant, that the latter is thereby mediately determined by the former.
math needs logic
Mathematics is distinguished from all other sciences except only ethics, in standing in no need of ethics.
mean two important
It is important to understand what I mean by semiosis . All dynamic action, or action of brute force, physical or psychical, either takes place between two subjects, whether they react equally upon each other, or one is agent and the other patient, entirely or partially, or at any rate is a resultant of such actions between pairs. But by "semiosis" I mean, on the contrary, an action, or influence, which is, or involves, a cooperation of three subjects, such as a sign, its object, and its interpretant, this tri-relative influence not being in any way resolvable into actions between pairs.
ideas ego unity
The consciousness of a general idea has a certain "unity of the ego" in it, which is identical when it passes from one mind to another. It is, therefore, quite analogous to a person, and indeed, a person is only a particular kind of general idea.
morning spring mean
Looking out of my window this lovely spring morning I see an azalea in full bloom. No, no! I do not see that; though that is the only way I can describe what I see. That is a proposition, a sentence, a fact; but what I perceive is not proposition, sentence, fact, but only an image which I make intelligible in part by means of a statement of fact. This statement is abstract; but what I see is concrete.
men satisfied every-man
Every man is fully satisfied that there is such a thing as truth, or he would not ask any question.
ontology logic mathematics
Mathematics is purely hypothetical: it produces nothing but conditional propositions.
essence giving different
The essence of belief is the establishment of a habit; and different beliefs are distinguished by the different modes of action to which they give rise.
knowledge men knowing
It is not knowing, but the love of learning, that characterizes the scientific man.
