He past is the weather that already happened and that, in a chronological line, has been left behind . It is known as past both at that time and at what happened in the period in question. For example: "The singer's addictions are already in the past", "The player's turbulent past came to light when he tried to cross the border and was stopped by the police", “Argentina was a very prosperous country in the past, but currently it suffers major economic problems and has more than half of the population below the poverty line”.
There are different ways of analyze last. There are those who believe that All the past time was better : It is a pessimistic position that does not trust the progress of Humanity, but defends the reality lived in previous years.
Another philosophical position, more grounded in reality, argues that the past must be remembered to rescue the positive and not to repeat the mistakes . In this sense, the past would be the basis on which the I presented and the future is planned.
A third position states that the past does not exist (or that, at least, it only exists in the minds of people ). According to this notion, the only thing that has real existence is the present: the past has already died and the future has not yet arrived.
Despite this ideological distinction, it is almost inevitable to feel a certain nostalgia about our past. Even those who claim to look to the future, always think about development and growth, love innovation and not fear change, go through moments of weakness when they long for childhood, innocence typical of that time when, in the case of the most fortunate, there were no obligations, death or uprooting, among so many different ailments that can suffer in life.
The past gives a sense of security, of control, as is known and does not change. Of course we have the power to remember it with certain modifications that conform to the needs that we have at every stage of our lives. It is very common that the same fact is brought to memory with different connotations each time, depending on the feelings present at the time of evoking it; For example, someone who manages to leave poverty behind may scorn his childhood full of deficiencies and, later, if he suffers a very deep loss, long for it because of the emotional security he felt, despite the economic instability.
As often happens in other cases, a balanced posture is the most advisable, since it allows us to learn from the past to build a better present. It is inevitable to rely on experience to grow; What would become of a scientist without starting from the infinity of discoveries made by his predecessors, or of a writer without having cultivated reading through the great classics? In many cases, pride leads certain people to seek a reality completely detached from the roots, believing that only in this way is it possible to achieve authenticity. And this could not be further from the truth.
No one can choose their origins, and people who seek answers for everything often regret many events from their past, be they parents' teachings that lacked meaning or morals, or ideas they used to defend in adolescence and with whom they no longer feel identified. But someone capable of questioning those events and capitalizing on what they learned from mistakes has an incalculable wealth and there probably aren't many obstacles that I can't overcome in the lifetime.
For the physical , the past of an event X is formed by the totality of the points of the spatio-temporal dimension that can influence what happens in X.
