Quality (philosophy) in the context of "Intension"

Rationality is the quality of being guided by or based on reason. In this regard, a person acts rationally if they have a good reason for what they do, or a belief is rational if it is based on strong evidence. This quality can apply to an ability, as in a rational animal, to a psychological process, like reasoning, to mental states, such as beliefs and intentions, or to persons who possess these other forms of rationality. A thing that lacks rationality is either arational, if it is outside the domain of rational evaluation, or irrational, if it belongs to this domain but does not fulfill its standards.

There are many discussions about the essential features shared by all forms, or accounts, of rationality. According to reason-responsiveness accounts, to be rational is to be responsive to reasons. For example, dark clouds are a reason for taking an umbrella, which is why it is rational for an agent to do so in response. An important rival to this approach are coherence-based accounts, which define rationality as internal coherence among the agent's mental states. Many rules of coherence have been suggested in this regard, for example, that one should not hold contradictory beliefs or that one should intend to do something if one believes that one should do it.

A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms a sign of disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs (notices, road signs, etc., collectively known as signage) generally inform or instruct using written text, symbols, pictures or a combination of these.

The philosophical study of signs and symbols is called semiotics; this includes the study of semiosis, which is the way in which signs (in the semiotic sense) operate.

Quantity or amount is a property that includes numbers and quantifiable phenomena such as mass, time, distance, heat, angle, and information. Quantities can commonly be compared in terms of "more", "less", or "equal", or by assigning a numerical value multiple of a unit of measurement. Quantity is among the basic classes of things along with quality, substance, change, and relation. Some quantities are such by their inner nature (as number), while others function as states (properties, dimensions, attributes) of things such as heavy and light, long and short, broad and narrow, small and great, or much and little.

Under the name of multitude comes what is discontinuous and discrete and divisible ultimately into indivisibles, such as: army, fleet, flock, government, company, party, people, mess (military), chorus, crowd, and number; all which are cases of collective nouns. Under the name of magnitude comes what is continuous and unified and divisible only into smaller divisibles, such as: matter, mass, energy, liquid, material—all cases of non-collective nouns.

Workmanship is a human attribute relating to knowledge and skill at performing a task. Workmanship is also a quality imparted to a product. The type of work may include the creation of handcrafts, art, writing, machinery and other products.

There are various names of God and many titles that refer to God, many of which enumerate the various qualities of a Supreme Being. The English word god (and its equivalent in other languages) is used by multiple religions as a noun to refer to different deities, or specifically to the Supreme Being, as denoted in English by the capitalized and uncapitalized terms God and god. Ancient cognate equivalents for the biblical Hebrew Elohim, one of the most common names of God in the Bible, include proto-Semitic El, biblical Aramaic Elah, and Arabic ilah. The personal or proper name for God in many of these languages may either be distinguished from such attributes, or homonymic. For example, in Judaism the tetragrammaton is sometimes related to the ancient Hebrew ehyeh ("I will be"). It is connected to the passage in Exodus 3:14 in which God gives his name as אֶהְיֶה אֲשֶׁר אֶהְיֶה (Ehyeh Asher Ehyeh), where the verb may be translated most basically as "I Am that I Am", "I shall be what I shall be", or "I shall be what I am". In the passage, YHWH, the personal name of God, is revealed directly to Moses.

Correlation between various theories and interpretation of the name of "the one God", used to signify a monotheistic or ultimate Supreme Being from which all other divine attributes derive, has been a subject of ecumenical discourse between Eastern and Western scholars for over two centuries. In Christian theology the word is considered a personal and a proper name of God. On the other hand, the names of God in a different tradition are sometimes referred to by symbols. The question whether divine names used by different religions are equivalent has been raised and analyzed.
