Once a man’s understanding has settled on something (either because it is an accepted belief or because it pleases him), it draws everything else also to support and agree with it. And if it encounters a larger number of more powerful countervailing examples, it either fails to notice them, or disregards them, or makes fine distinctions to dismiss and reject them, and all of this with much dangerous prejudice, to preserve the authority of its first conceptions.

[Intellectus humanus in iis quae semel placuerunt (aut quia recepta sunt et credita, aut quia delectant), alia etiam omnia trahit ad suffragationem et consensum cum illis: et licet major sit instantiarum vis et copia, quae occurrunt in contrarium; tamen eas aut non observat, aut contemnit, aut distinguendo summovet et rejicit, non sine magno et pernicioso praejudicio, quo prioribus illis syllepsibus authoritas maneat inviolata.]

Francis Bacon (1561-1626) English philosopher, scientist, author, statesman
Instauratio Magna [The Great Instauration], Part 2 “Novum Organum [The New Organon],” Book 1, Aphorism # 46 (1620) [tr. Silverthorne (2000)]

(Source (Latin)). Alternate translations:

The human understanding, when any preposition has been once laid down, (either from general admission and belief, or from the pleasure it affords,) forces every thing else to add fresh support and confirmation; and although more cogent and abundant instances may exist to the contrary, yet either does not observe or despises them, or gets rid of and rejects them by some distinction, with violent and injurious prejudice, rather than sacrifice the authority of its first conclusions.
[tr. Wood (1831)]

The human understanding when it has once adopted an opinion (either as being the received opinion or as being agreeable to itself) draws all things else to support and agree with it. And though there be a greater number and weight of instances to be found on the other side, yet these it either neglects and despises, or else by some distinction sets aside and rejects; in order that by this great and pernicious predetermination the authority of its former conclusions may remain inviolate.
[tr. Spedding (1858)]

The human Intellect, in those things which have once pleased it (either because they are generally received and believed, or because they suit the taste), brings everything else to support and agree with them; and though the weight and number of contradictory instances be superior, still it either overlooks or despises them, or gets rid of them by creating distinctions, not without great and in jurious prejudice, that the authority of these previous conclusions may be maintained inviolate.
[tr. Johnson (1859)]

Once a human intellect has adopted an opinion (either as something it likes or as something generally accepted), it draws everything else in to confirm and support it. Even if there are more and stronger instances against it than there are in its favour·, the intellect either overlooks these or treats them as negligible or does some line-drawing that lets it shift them out of the way and reject them. This involves a great and pernicious prejudgment by means of which the intellect’s former conclusions remain inviolate.
[tr. Bennett (2017)]
