The Peanese convention for the use of dots as brackets has the disadvantage that it gives only an awkward method for representing chains of indefinite length, such as the compound implicationSuch chains occur frequently in logical investigations of a metatheoretic nature, and it is convenient to have a systematic method of abbreviating them. The most obvious method of doing this would be to leave the parentheses out entirely, and to understand that in such cases the implication sign or other operation (...) appearing on the extreme left is the most inclusive; but this method, which has been followed by Quine, is at variance with our ordinary algebraic usage, in which we write a − b + c − d for ((a − b) + c) − d, and consequently leads to confusion. It is desirable to have a modification of the Peanese convention which gives a simple method of representing such chain implications, and at the same time avoids this difficulty.Such a modification is easily obtained by generalizing somewhat a procedure of Church. The latter author uses only a single dot, which he writes on the right of an operator to signify a bracket extending from that point to the end of the formula (or parenthesized expression). If dots are used only on the right of operations this is all that can be desired. But the essential idea of this device can be extended to the case where dots are used also on the left, as follows: let us suppose that a group of dots on the right of an operation or prefix denotes the beginning of a bracket which extends to the right until it meets a group with an equal or larger number of dots on the left of an operation; and that the scope of a group of dots on the left of an operation shall extend to the left until it reaches a larger group of dots on the right of some operation.

In a given polity, interactions between the Governed and the Governing Strata are symbiotic. The Governed desire, and indeed need, infrastructure services organized. If such basic foundations are not provided, the economic activity so deeply cherished by both groups cannot be realized. The Governing Strata cannot function without the Governed. After all, without the Governed, there will not be a polity; hence nothing to govern. Regardless of the politico-economic system in effect, this co-dependence is inevitable, inescapable, indenturing both groups to (...) each other. This is the case, regardless of the designation, functions, or the style of the governance system. It matters not if the designation or philosophy of the said governance is a variation of pluralism or authoritarianism by a minority. (shrink)

It is argued that dispositional explanations are radically incomplete causal explanations that are employed when (1) a description of the stimuli is insufficient to account for the object's response and (2) not enough is known about the object to specify what its specific causal contribution is. ryle's failure to refer to the causal contribution of the organism in his account of dispositions is regarded as a serious weakness.
