From today's featured article

Premises are true or false statements that act as the starting points of arguments by presenting reasons to substantiate or refute assertions. For example, the premises "all men are mortal" and "Socrates is a man" guarantee the conclusion "Socrates is mortal". Explicit premises are overtly stated, whereas implicit premises are tacitly assumed without appearing in the text. Independent premises give distinct reasons, whereas dependent premises only work in combination. The role of premises in arguments is typically either to preserve truth or to transfer justification to a conclusion. To succeed, premises must be true or justified and must be relevant to the conclusion. In deductively valid arguments, true premises guarantee a true conclusion. In non-deductive arguments, the premises aim to make the conclusion more reasonable or increase its probability. Defective arguments, called fallacies, can often arise from faulty premises. Premises are central to many fields, including logic, argumentation theory, mathematics, philosophy, science, and law. (Full article...)

Today's featured picture

Leotia lubrica, commonly referred to as a jelly baby, is a species of fungus in the family Leotiaceae. The species produces small fruit bodies up to 6 cm (2.4 in) in height, featuring a head and a stalk. The youngest fruit bodies are small and conical, but the fertile head quickly grows from the stalk. Ochre with tints of olive green, the heads are irregularly shaped, while the stalk, of a similar colour, attaches them to the ground. The appearance can be somewhat variable and is similar to a number of other species. It has been recorded in Europe, Asia, North America, and Australasia. Growing in woodland among moss, plant detritus or other habitats, the fruit bodies are typically found in large numbers, though they can grow in tight clumps or even individually. The species may feed as a saprotroph or possibly obtains nutrition from living trees through ectomycorrhizae. It is often described as inedible, despite its common name, but has occasionally been reported as a good edible. This cluster of L. lubrica fruit bodies was photographed near Erbach in Baden-Württemberg, Germany.
