Time (n.) is created by individual perception, and that therefore, nothing prevents mankind as such from having no future at all if for example our genus evolves to enjoy other varieties of being and dreaming, beyond man's notion of time.
Time (n.) only exist when perceived by human consciousness. Should all of 'mankind' vanish, 'time' itself will cease to exist, as the word 'time' is merely a description of human cognition.
Time (n.) is the creation of the individual experiencing it, rather than of human consciousness as a whole.There is no time for any given individual before that individual's first memory, and there will be no time for that individual after his death.
Time (n.) is so boundless at first blush, but it is, in fact, a prison.
Time (n.) is rhythm: the insect rhythm of a warm humid night, brain ripple, breathing, the drum in my temple—these are our faithful timekeepers; and reason corrects the feverish beat.
