Note 732 — Chapter V · (continued 2)

‘All reasoning must be from first principles; and for first principles no other reason can be given but this, that, by the constitution of our nature, we are under a necessity of assenting to them.’ Reid's Inquiry, p. 140. ‘All reasoning is from principles.’ … ‘Most justly, therefore, do such principles disdain to be tried by reason, and laugh at all the artillery of the logician when it is directed against them.’ p. 372. ‘All knowledge got by reasoning must be built upon first principles.’ Reid's Essays, vol. ii. p. 220. ‘In every branch of real knowledge there must be first principles, whose truth is known intuitively, without reasoning, either probable or demonstrative. They are not grounded on reasoning, but all reasoning is grounded on them.’ p. 360.
