C. D. Broad

Charlie Dunbar Broad (30 December 1887 – 11 March 1971), usually cited as C. D. Broad, was an English epistemologist, historian of philosophy, philosopher of science, moral philosopher, and writer on the philosophical aspects of psychical research. He was known for his thorough and dispassionate examinations of arguments in such works as Scientific Thought, published in 1923, The Mind and Its Place in Nature, published in 1925, and An Examination of McTaggart's Philosophy, published in 1933.

Broad's essay on "Determinism, Indeterminism, and Libertarianism" in Ethics and the History of Philosophy (1952) introduced the philosophical terms "occurrent causation" and "non-occurrent causation", which became the basis for today's "agent causal" and "event causal" distinctions in the debates on libertarian free will.

Life

Broad was born in Harlesden, in Middlesex, England. He was educated at Dulwich College from 1900 until 1906. He gained a scholarship to study at Trinity College, Cambridge in 1906. In 1910 he graduated with First-Class Honours, with distinction.

Compact disc

Compact disc (CD) is a digital optical disc data storage format. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CDs and audio CD players have been commercially available since October 1982.

Standard CDs have a diameter of 120 millimetres (4.7 in) and can hold up to about 80 minutes of uncompressed audio or about 700 MiB of data. The Mini CD has various diameters ranging from 60 to 80 millimetres (2.4 to 3.1 in); they are sometimes used for CD singles, storing up to 24 minutes of audio, or delivering device drivers.

At the time of the technology's introduction in 1982, a CD had greater storage capacity than a personal computer hard drive. By 2010 hard drives commonly had capacities exceeding those of CDs by a factor of several thousand.

2C-D

2C-D (2,5-dimethoxy-4-methylphenethylamine, also known as 2C-M) is a psychedelic drug of the 2C family that is sometimes used as an entheogen. It was first synthesized in 1970 by a team from the Texas Research Institute of Mental Sciences, and its activity was subsequently investigated in humans by Alexander Shulgin. The full name of the chemical is 2,5-dimethoxy-4-methylphenethylamine. In his book PiHKAL (Phenethylamines i Have Known And Loved), Shulgin lists the dosage range as being from 20 to 60 mg and many people recommend higher doses. Lower doses (generally 10 mg or less) of 2C-D have been explored as a potential nootropic, albeit with mixed results. 2C-D is generally taken orally, though may be insufflated (i.e. taken nasally). Insufflating tends to cause intense pain, however, and the dosage level is usually much lower, typically in the region of 1 to 15 mg.

Not much information is known about the toxicity of 2C-D, as no major studies have been conducted. According to Shulgin, the effects of 2C-D typically last for 4–6 hours. Shulgin himself referred to this substance as a “pharmacological tofu,” meaning that when mixed with other substances, it can extend or potentiate their effects without coloring the experience too much, in a manner similar to how tofu absorbs the flavors of sauces or spices it is cooked with. Some people have claimed 2C-D is relatively uninteresting on its own, but many other users have strongly disagreed with this assessment and believe instead 2C-D to be a true psychedelic in its own right. Hanscarl Leuner, working in Germany, explored the use of 2C-D under the name LE-25 in psychotherapeutic research.
