Reginald Scot, in the Discoverie of Witchcraft, says that the aforesaid exclamation of Fazio was the Paracelsian charm to drive away spirits that haunt any house. Cardan gives his impressions of musicians: "Unde nostra ætate neminem ferine musicum invenias, qui non omni redundat vitiorum genere.
Bishop Lowth says of it ironically, 'The Divine Legation, it seems, contains in it all knowledge, divine and human, ancient and modern; it treats as of its proper subject, de omni scibili et de quolibet ente; it is a perfect encyclopædia; it includes in itself all history, chronology, criticism, divinity, law, politics, &c. &c. A Letter to the Right Rev. Samuel Chandler, an eminent Dissenter.
In every religious and moral use of the word, God, taken absolutely, that is, not as a God, or the God, but as God, a relativity, a distinction in kind 'ab omni quod non est Deus', is so essentially implied, that it is a matter of perfect indifference, whether we assert a world without God, or make God the world. The one is as truly Atheism as the other.
So long as what were termed Universals were regarded as a peculiar kind of substances, having an objective existence distinct from the individual objects classed under them, the dictum de omni conveyed an important meaning; because it expressed the intercommunity of nature, which it was necessary on that theory that we should suppose to exist between those general substances and the particular substances which were subordinated to them.
The dictum de omni et nullo, viz. that whatever can be affirmed or denied of a class can be affirmed or denied of everything included in the class, which is a true account generalised of the constituent parts of the syllogism in the first figure, was thought the basis of the syllogistic theory.
"Man may securely sin, but safely never." "Vulgarem locutionem anpellamus cam qua infantes adsuefiunt ab adsistentibus cum primitus distinguere voces incipiunt: vel, quod brevius dici potest, vulgarem locutionem asserimus quam sine omni regula, nutricem imitantes accepimus." Dantes, de Vulg. Eloquio, Lib I. cap. i.
M. Olbinett busied himself in passing round refreshments which were very acceptable in such hot weather. Half a barrel of Scotch ale was sent in bodily. Barclay and Co. was declared to be the greatest man in Great Britain, even above Wellington, who could never have manufactured such good beer. This was a Scotch estimate. Jacques Paganel drank largely, and discoursed still more de omni re scibili.
Quod est istud crimen senectutis, cum id ei videatis cum adulescentia esse commune? 68 Sensi ego in optimo filio, tu in exspectatis ad amplissimam dignitatem fratribus, Scipio, mortem omni aetati esse communem. At sperat adulescens diu se victurum, quod sperare idem senex non potest. Insipienter sperat; quid enim stultius quam incerta pro certis habere, falsa pro veris?
The class is nothing but the objects contained in it: and the dictum de omni merely amounts to the identical proposition, that whatever is true of certain objects, is true of each of those objects. If all ratiocination were no more than the application of this maxim to particular cases, the syllogism would indeed be, what it has so often been declared to be, solemn trifling.
When a philosopher adopted fully the Nominalist view of the signification of general language, retaining along with it the dictum de omni as the foundation of all reasoning, two such premises fairly put together were likely, if he was a consistent thinker, to land him in rather startling conclusions.
