Present

Last updated

The present is the period of time that is occurring now. The present is contrasted with the past, the period of time that has already occurred, and the future, the period of time that has yet to occur.

It is sometimes represented as a hyperplane in space-time, [1] typically called "now", although modern physics demonstrates that such a hyperplane cannot be defined uniquely for observers in relative motion. The present may also be viewed as a duration. [2] [3]

Historiography

Contemporary history describes the historical timeframe immediately relevant to the present time and is a certain perspective of modern history.

Quotations

You shouldn't chase after the past or place expectations on the future. What is past is left behind. The future is as yet unreached. Whatever quality is present you clearly see right there, right there.

Buddha, Bhaddekaratta Sutta [4]

What we perceive as present is the vivid fringe of memory tinged with anticipation.

Alfred North Whitehead, The Concept of Nature [5]

Philosophy of time

"The present" raises the question: "How is it that all sentient beings experience now at the same time?" [6] There is no logical reason why this should be the case and no easy answer to the question.[ citation needed ]

In Buddhism

Buddhism and many of its associated paradigms emphasize the importance of living in the present moment—being fully aware of what is happening, and not dwelling on the past or worrying about the future. [7] This does not mean that they encourage hedonism, but merely that constant focus on one's current position in space and time (rather than future considerations, or past reminiscence) will aid one in relieving suffering. They teach that those who live in the present moment are the happiest. [8] A number of meditative techniques aim to help the practiser live in the present moment.

Christianity and eternity

Christianity views God as being outside of time and, from the divine perspective past, present and future are actualized in the now of eternity. This trans-temporal conception of God has been proposed as a solution to the problem of divine foreknowledge (i.e. how can God know what we will do in the future without us being determined to do it) since at least Boethius. [9] Thomas Aquinas offers the metaphor of a watchman, representing God, standing on a height looking down on a valley to a road where past, present and future, represented by the individuals and their actions strung out along its length, are all visible simultaneously to God. [10] Therefore, God's knowledge is not tied to any particular date. [11]

It follows from Albert Einstein's Special Theory of Relativity that there is no such thing as absolute simultaneity. When care is taken to operationalise "the present", it follows that the events that can be labeled as "simultaneous" with a given event, can not be in direct cause-effect relationship. Such collections of events are perceived differently by different observers. Instead, when focusing on "now" as the events perceived directly, not as a recollection or a speculation, for a given observer "now" takes the form of the observer's past light cone. The light cone of a given event is objectively defined as the collection of events in causal relationship to that event, but each event has a different associated light cone. One has to conclude that in relativistic models of physics there is no place for "the present" as an absolute element of reality, and only refers to things that are close to us. [12] Einstein phrased this as: "People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion". [13] [14]

Cosmology

In physical cosmology, the present time in the chronology of the universe is estimated at 13.8 billion years after the singularity determining the arrow of time. In terms of the cosmic expansion history, it is in the dark-energy-dominated era, after the universe's matter content has become diluted enough for dark energy to dominate the total energy density. It is also in the universe's Stelliferous Era, after enough time for superclusters to have formed (at about 5 billion years), but before the accelerating expansion of the universe has removed the local supercluster beyond the cosmological horizon (at about 150 billion years). [15]

Archaeology, geology, etc.

In radiocarbon dating, the "present" is defined as AD 1950.

Grammar

In English grammar, actions are classified according to one of the following twelve verb tenses: past (past, past continuous, past perfect, or past perfect continuous), present (present, present continuous, present perfect, or present perfect continuous), or future (future, future continuous, future perfect, or future perfect continuous). [16] The present tense refers to things that are currently happening or are always the case. [16] For example, in the sentence, "she walks home everyday," the verb "walks" is in the present tense because it refers to an action that is regularly occurring in the present circumstances.

Verbs in the present continuous tense indicate actions that are currently happening and will continue for a period of time. [16] In the sentence, "she is walking home," the verb phrase "is walking" is in the present continuous tense because it refers to a current action that will continue until a certain endpoint (when "she" reaches home). Verbs in the present perfect tense indicate actions that started in the past and is completed at the time of speaking. [17] For example, in the sentence, "She has walked home," the verb phrase "has walked" is in the present perfect tense because it describes an action that began in the past and is finished as of the current reference to the action. Finally, verbs in the present perfect continuous tense refer to actions that have been continuing up until the current time, thus combining the characteristics of both the continuous and perfect tenses. [16] An example of a present perfect continuous verb phrase can be found in the sentence, "she has been walking this route for a week now," where "has been walking" indicates an action that was happening continuously in the past and continues to happen continuously in the present.

In grammar, tense is a category that expresses time reference. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns.

In linguistics, aspect is a grammatical category that expresses how an action, event, or state, as denoted by a verb, extends over time. Perfective aspect is used in referring to an event conceived as bounded and unitary, without reference to any flow of time during the event. Imperfective aspect is used for situations conceived as existing continuously or repetitively as time flows.

A verb is a word that in syntax generally conveys an action, an occurrence, or a state of being. In the usual description of English, the basic form, with or without the particle to, is the infinitive. In many languages, verbs are inflected to encode tense, aspect, mood, and voice. A verb may also agree with the person, gender or number of some of its arguments, such as its subject, or object. Verbs have tenses: present, to indicate that an action is being carried out; past, to indicate that an action has been done; future, to indicate that an action will be done.

<span class="mw-page-title-main">Future</span> Time after the present

The future is the time after the past and present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end. In the Occidental view, which uses a linear conception of time, the future is the portion of the projected timeline that is anticipated to occur. In special relativity, the future is considered absolute future, or the future light cone.

In linguistics, a participle is a nonfinite verb form that has some of the characteristics and functions of both verbs and adjectives. More narrowly, participle has been defined as "a word derived from a verb and used as an adjective, as in a laughing face".

<span class="mw-page-title-main">English verbs</span> Verbs in the English language

Verbs constitute one of the main parts of speech in the English language. Like other types of words in the language, English verbs are not heavily inflected. Most combinations of tense, aspect, mood and voice are expressed periphrastically, using constructions with auxiliary verbs.

The present tense is a grammatical tense whose principal function is to locate a situation or event in the present time. The present tense is used for actions which are happening now. In order to explain and understand present tense, it is useful to imagine time as a line on which the past tense, the present and the future tense are positioned. The term present tense is usually used in descriptions of specific languages to refer to a particular grammatical form or set of forms; these may have a variety of uses, not all of which will necessarily refer to present time. For example, in the English sentence "My train leaves tomorrow morning", the verb form leaves is said to be in the present tense, even though in this particular context it refers to an event in future time. Similarly, in the historical present, the present tense is used to narrate events that occurred in the past.

<span class="mw-page-title-main">Spanish verbs</span> Verbs in the Spanish language

Spanish verbs form one of the more complex areas of Spanish grammar. Spanish is a relatively synthetic language with a moderate to high degree of inflection, which shows up mostly in Spanish conjugation.

The perfect tense or aspect is a verb form that indicates that an action or circumstance occurred earlier than the time under consideration, often focusing attention on the resulting state rather than on the occurrence itself. An example of a perfect construction is I have made dinner. Although this gives information about a prior action, the focus is likely to be on the present consequences of that action. The word perfect in this sense means "completed".

The continuous and progressive aspects are grammatical aspects that express incomplete action or state in progress at a specific time: they are non-habitual, imperfective aspects.

<span class="mw-page-title-main">Past</span> Events that occurred before a given time point

The past is the set of all events that occurred before a given point in time. The past is contrasted with and defined by the present and the future. The concept of the past is derived from the linear fashion in which human observers experience time, and is accessed through memory and recollection. In addition, human beings have recorded the past since the advent of written language. The first known use of the word "past" was in the fourteenth century; it developed as the past participle of the Middle English verb passen meaning "to pass."

The imperfect is a verb form that combines past tense and imperfective aspect. It can have meanings similar to the English "was walking" or "used to walk". It contrasts with preterite forms, which refer to a single completed event in the past.

In French grammar, verbs are a part of speech. Each verb lexeme has a collection of finite and non-finite forms in its conjugation scheme.

The sequence of tenses is a set of grammatical rules of a particular language, governing the agreement between the tenses of verbs in related clauses or sentences.

<span class="mw-page-title-main">Simple present</span> Verb form

The simple present, present simple or present indefinite is one of the verb forms associated with the present tense in modern English. It is commonly referred to as a tense, although it also encodes certain information about aspect in addition to the present time. The simple present is the most commonly used verb form in English, accounting for more than half of verbs in spoken English.

The grammar of Macedonian is, in many respects, similar to that of some other Balkan languages, especially Bulgarian. Macedonian exhibits a number of grammatical features that distinguish it from most other Slavic languages, such as the elimination of case declension, the development of a suffixed definite article, the lack of an infinitival verb, and the constructions with ima/nema formed with the auxiliary "to have", among others.

Tense–aspect–mood or tense–modality–aspect is a group of grammatical categories that are important to understanding spoken or written content, and which are marked in different ways by different languages.

In linguistics, the aspect of a verb is a grammatical category that defines the temporal flow in a given action, event, or state. As its name suggests, the habitual aspect, not to be confused with iterative aspect or frequentative aspect, specifies an action as occurring habitually: the subject performs the action usually, ordinarily, or customarily. As such, the habitual aspect provides structural information on the nature of the subject referent, "John smokes" being interpretable as "John is a smoker", "Enjoh habitually gets up early in the morning" as "Enjoh is an early bird". The habitual aspect is a type of imperfective aspect, which does not depict an event as a single entity viewed only as a whole but instead specifies something about its internal temporal structure.

From a semantic perspective, a tense is a temporal circumstance in which an event takes place relative to a given point in time. It is absolute (primary) if it relates the represented event to the time of the speech event and it is relative if it relates the represented event to the time of another event in the context of discourse. In turn, a relative tense may be “relative to absolute” (secondary) if it relates the represented event to the primary tense. Read more about possible tenses in the article on grammatical tense.
