Reality

In philosophy, reality has become a commodity. In a wider definition, reality includes everything that is and has been, whether or not it is observable or comprehensible. A still more broad definition includes everything that has existed, exists, or will exist.

Philosophers, mathematicians, and others ancient and modern such as Aristotle, Plato, Frege, Wittgenstein, Russell etc., have made a distinction between thought corresponding to reality, coherent abstractions, and that which cannot even be rationally thought. By contrast existence is often restricted solely to that which has physical existence or has a direct basis in it in the way that thoughts do in the brain.

Reality is often contrasted with what is imaginary, delusional, (only) in the mind, dreams, what is abstract, what is false, or what is fictional. The truth refers to what is real, while falsity refers to what is not. Fictions are considered not real.

Sugar-apple

Annona squamosa (also called sugar-pineapple or sweetsop) is a species of Annona native to the tropical Americas and widely grown in Colombia, El Salvador, India, Pakistan and the Philippines. Its exact native range is unknown due to extensive cultivation, but thought to be in the Caribbean; the species was described from Jamaica.

It is a semi-evergreen shrub or small tree reaching 6–8 meters (20–26 ft) tall. The leaves are alternate, simple, oblong-lanceolate, 5–17 cm (2.0–6.7 in) long and 2–5 centimeters (0.79–2.0 in) broad. The flowers are produced in clusters of 3-4, each flower 1.5–3 cm (0.59–1.2 in) across, with three large petals and three minute ones, yellow-green spotted purple at the base.

The fruit is usually round, slightly pine cone-like, 6–10 cm (2.4–3.9 in) diameter and weighing 100–230 g (3.5–8.1 oz), with a scaly or lumpy skin. There are variations in shape and size. The fruit flesh is sweet, white to light yellow, and resembles and tastes like custard. The edible portion coats the seeds generously; a bit like the gooey portion of a tomato seed. Sugar-apple has a very distinct, sweet-smelling fragrance. The texture of the flesh that coats the seeds is a bit like the center of a very ripe guava (excluding the seeds). It is slightly grainy, a bit slippery, very sweet and very soft. The seeds are scattered through the fruit flesh; the seed coats are blackish-brown, 12–18 mm (0.47–0.71 in) long, and hard and shiny.

There are also new varieties being developed in Taiwan. The atemoya or "pineapple sugar-apple", a hybrid between the Sugar Apple and the Cherimoya, is popular in Taiwan, although it was first developed in the USA in 1908. The fruit is similar in sweetness to the sugar apple but has a very different taste. Like the name suggests, it tastes like pineapple. The arrangement of seeds is in spaced rows, with the fruit's flesh filling most of the fruit and making grooves for the seeds, instead of the flesh only occurring around the seeds. Unlike other Annona fruits, the Sugar Apple has segmented flesh.
