Philosopher (deceased).
As an example of Being conceived as consisting in the acting of its subject upon other objects, we have Actuality.

Although assertoriness, with it metaphysical correspondent, actuality, is the absence of modality, yet it has to be considered from the point of view of modality.

The double relation of equiparance which constitutes duality is surd. It may be described in words, but those words can only be understood by means of reference to certain experiences; just as a person may be told that a piece of textile fabric is a yard wide,

…while action may,in the first place,be purely physical and open to outward inspection, it may also, in the second place, be purely mental and knowable (by others,at any rate, than the actor) only through outward symptoms or indirect effects,and thirdly it may be partly inward and partly outward,

Habermas criticizes both me and Castoriadis for indulging in Lebenphilosophie; this charge means, roughly, that we both want to poeticize rather than rationalize.

In the ideas of Firstness, Secondness, and Thirdness, the three elements, or Universal Categories, appear under their forms of Firstness. They appear under their forms of Secondness in the ideas of Facts of Firstness, or Qualia, Facts of Secondness, or Relations, and Facts of Thirdness, or Signs;

Philosophers are fond of saying that their field boosts critical thinking. Two of them decided to put that claim to the test.

Science is research; and research is science, from the first moment when the researcher casts aside all desire to prove his present opinions right, and burns with ardent desire to find out wherein they are wrong. Science thus consists in a disposition of living men; and therefore,

Logic treats of signs. A sign is a third.

Activity implies a generalization of effort; and effort is a two-sided idea, effort and resistance being inseparable, and therefore the idea of Actuality has also a dyadic form.

That conception of Aristotle which is embodied for us in the cognate origin of the terms actuality and activity is one of the most deeply illuminating products of Greek thinking.

The waking state is a consciousness of reaction; and as the consciousness itself is two sided, so it has also two varieties; namely, action, where our modification of other things is more prominent than their reaction on us, and perception,

Observe, if you please, the difference of meaning between a consequent the thing led to, and a consequence, the general fact by virtue of which a given antecedent lead to a certain consequent.

But since this, after all, is only conjectural, I have on reflexion decided to give this kind of reasoning the name of retroduction to imply that it turns back and leads from the consequent of an admitted consequence, to its antecedent.

A is that process in which the mind goes over all the facts the case, absorbs them, digests them, sleeps over them, assimilates them, dreams of them, and finally is prompted to deliver them in a form, which, if it adds something to them,

Abduction furnishes all our ideas concerning real things, beyond what are given in perception, but is mere conjecture, without probative force.
November 21, 2025 at 2:27 AM
An Abduction is Originary in respect to being the only kind of argument which starts a new idea.

Happy World Philosophy Day to all who celebrate!

And to those who celebrate the importance of critical thinking about fundamental concepts, eg, rationality, meaning, inspiration, but shun the label 'philosophy'...

Happy Critical Thinking Day!

Argument is of three kinds: Deduction, Induction, and Abduction (usually called adopting a hypothesis).
November 20, 2025 at 3:58 PM
Methodeutic has a special interest in Abduction, or the inference which starts a scientific hypothesis. For it is not sufficient that a hypothesis should be a justifiable one.
November 20, 2025 at 12:55 AM
Abduction is reasoning which professes to be such that in case there is any ascertainable truth concerning the matter in hand, the general method of this reasoning, though not necessarily each special application of it, must eventually approximate to the truth.
