Consciousness concerns the feelings that accompany science and therefore signifies the awareness of what is happening in us. It is that inner knowledge that each has of good and evil; it forms the judgment that everyone does of his feelings according to the relationship they have with the principles of morality.
Formerly, with consciousness was meant something different from what is considered today in the psychological and philosophical settings. Not all the ancients divided man in mind and body. Indeed, there was a widespread idea that man had three functions relatively independent called "intellectual center", "center motor-instinctive" and "emotional center", located respectively in a part of the brain, in the final part of the spine (where once humans had the tail) and in the area of the solar plexus, in what are now called "the sympathetic and parasympathetic ganglia." "Consciousness" indicated that inner state of harmony between the three centers which, if reached, allowed man to elevate his own reason.
Traditional psychology indicates as consciousness a general function of its human capacity to assimilate knowledge. At first there is awareness, that is, active observation of the new knowledge; when this is followed by the final breakthrough of the new as part of the old, we can speak of consciousness.
This function, applied to the succession of phenomena of knowledge (not only sensory) generates the phenomenon of consciousness. As a dynamic phenomenon that continues over time can be identified as a real process.
• Consciousness - in ethics, can be defined as the ability to distinguish between good and evil, to act accordingly, as opposed to unconsciousness.
• In philosophy, consciousness acquires a theoretical value in those authors who understand it as interiority and make of the return to consciousness the recollection in themselves, the main tool to capture basic truths, otherwise inaccessible. Throughout the history of philosophy has assumed special and specific significance distinguishing itself from the generic term of awareness, activity with which the subject comes into possession of a knowledge.
The term consciousness has taken over the history of philosophy specific and particular meanings standing out from the generic term of consciousness to which is sometimes equated. The American philosopher John Searle joins awareness to self-consciousness: "Consciousness is a set of states and subjective processes. They are states of self-awareness, inner qualitative and individual. Consciousness is then that thing that begins to appear in the morning, when from the state of dream and sleep we pass to the waking state and continues for the duration of the day until the evening, when, returning to sleep, we become unconscious. The term consciousness is thus brought to psychoanalytic terminology that considers it as a condition of conscious attention as opposed to the unconscious situation of sleep.
As part of the consciousness philosophy has meant not only sensory data but also the complex interiority represented by feelings, emotions, desires, products of thought, as well as the sense of personal identity.
The process of the analysis of the inner life is called introspection that can sometimes be confused with reflection improperly understood as synonymous.
In Stoicism and Platonism to refer to consciousness meant to relate to the inner "voice", to that "dialogue of the soul with itself" which characterized the final production of the dialogic Platonic works where the literary and philosophical form of dialogue with an interlocutor vanished replaced by that of the monologue. The wise man of post-classical period of Greek philosophy is then the very one that moving away from worldly things and passions reflect on itself.
In defining consciousness, the philosophical vision seeks to grasp, therefore, the sense of knowing and describing the forms, especially those ‘a priori’, of its configuration, that means the dialectic that pervades the relationship of subject and object; in contrast, the scientific conception takes care of how this activity is achieved.
In the Kantian Critique of Practical Reason morality is understood as the voice of conscience, of our interiority, which claims the absolute value of the moral law sometimes misled by our sensitive inclinations.
According to Kant, taking up the ideas of Jean-Jacques Rousseau, is this a moral experience that unites all men regardless of their different cultural and intellectual conditions.
The Kantian statements were in contrast to the relativist morality of Renaissance that already with Michel de Montaigne in the Essays (1580), made it clear that in reality the so-called moral safe principles that vary according to the different areas of origin are inculcated in the child's mind that reached the 'adulthood, forget their origin and believes that those values are innate and have always been present in their consciousness.
With Descartes the term consciousness takes on the meaning of "subjective awareness" of himself, a direct consciousness of ourselves as to be safe while all mental contents of which we are conscious are only "ideas".
This Cartesian conception is found throughout the English empiricism up to David Hume who arrives to solipsism, (i.e. the belief that everything the individual perceives is created by his conscience) because he argues that thought can go to the limits of universe but always remaining within the essential purview of consciousness and knowing only sensitive "impressions" or "ideas" of reason without any cognitive certainty.
Against this interpretation reacted Immanuel Kant's Critique of Pure Reason where it distinguishes empirical consciousness, based on the single individual sensitivity and such to belong only to ourselves individually, and a consciousness in general or "transcendental apperception" that is expressed in the '' I think ", an activity of thought that belongs to all men, but to none of them in particular, structurally identical in all as a formal activity of knowing which is realized through ‘a priori’ synthetic judgment through the different" categories ".
The Kantian ‘I think’ will become the ‘absolute I’ of Fichte and of the first Schelling: while the individual ‘empirical ‘I’ is found to be always limited by the ‘non-I’, the objects, in the theoretical and practical activity, the absolute ‘I’, principle of all reality, in opposition to the ‘non-I’, in an original self-awareness activity, self-production (self-knowledge) and self-creation.
The intentionality, originally a concept of scholastic philosophy, was reintroduced in contemporary philosophy by the philosopher and psychologist Franz Brentano in his work 'Psychology from the empirical point of view'.
With the intentionality of consciousness or mind is meant the idea that consciousness is always directed to an object, which had always a content. Consciousness is so tense to the knowledge of the outside world while man with self-consciousness will become aware of his rationality as connected to reality.
The understanding of consciousness as awareness of something is found in the twentieth century in the philosophy of Husserl and some authors of existentialism such as Jean Paul Sartre's, Karl Jaspers.
The necessary reference of consciousness towards an object is called by Husserl, in the work ‘Ideas for a pure phenomenology’, "intentionality" and this meaning has penetrated into contemporary research, both in the continental and analytical philosophy.
In many cultural systems, consciousness is likened to the soul. However, the metaphysical sense of consciousness is only a philosophical abstraction that originates from different religious beliefs as a pure act of faith.
As a conclusion, it is in the consciousness and by virtue of the same, that cognitive science and cognitive psychology - but also, more generally, knowledge and cognition - find their common ground: that unity to which both can be traced. A unity that keeps the duality, and therefore the differentiation that justifies the multipliciy of experience, but also transcends it, in the ideal value that is intended to express.
