most are less indivisible than they are part and parcel of each other
of the group
not individuals

*individual (adj.) early 15c., "one and indivisible" (with reference to the Trinity), from Medieval Latin individualis, from Latin individuus "indivisible," from in- "not, opposite of" (see in- (1)) + dividuus "divisible," from dividere "divide" (see divide). Not common before c.1600 and the 15c. usage might be isolated. Sense of "single, separate" is 1610s; meaning "intended for one person" is from 1889.
