It marks a progressive improvement when, in time, it became customary, on receiving a denunciation, to interrogate the informer whether he knew if the accused was a drunkard or suffered from any mental disturbance and, in instructions to commissioners in taking testimony, these inquiries were directed always to be made. This was a praiseworthy precaution, and the modern softening of temper produced a marked improvement in the treatment of the insane. This is well exhibited in 1818, in the case of Pedro Benito Lobariñas, in which the Suprema ordered the Santiago tribunal to treat him with especial kindness, and to give him every comfort compatible with his safe-keeping. Confidential persons, as well as the physicians, are to be admitted to him, who in friendly talk could form an estimate of his mental condition, while investigations were also to be made at his place of abode. Still, the outcome of the case shows the conflict between humanity and extreme dread of doctrinal error. His offence was simply some "propositions" and, in view of his sanity in all else, and his experience as a garden laborer, he was to be handed over to the gardener of some convent so walled as to prevent his escape, and to forbid his speaking with any one, so that he might have no chance to disseminate his heresies.[170]
As for the other pleas in abatement, such as intoxication, sudden anger, thoughtlessness, ignorance, jocularity and the like, they could only be advanced in minor cases, like blasphemy and propositions not involving formal heresy. In such matters they were often alleged in extenuation and were given more or less consideration, according to the temper of the tribunal, the penalties, not infrequently, being moderated in consequence.
Defence, when the accused denied the charge, was practically limited to _tachas_ and _abonos_--the former being the disabling of witnesses by proving enmity or other disability, the latter being the accumulation of evidence to prove good character and assiduous religious observance. The _interrogatorio de indirectas_, to secure testimony disproving or explaining away specific accusations, was occasionally employed, and sometimes flaws or contradictions in the incriminating evidence were exposed, or an alibi might be proved when time and place were specified in the publication, but these cases were exceptional. In the great mass of trials on serious charges, no attempt at defence was made except by _tachas_ and _abonos_. To the latter little attention was usually vouchsafed, and the struggle, as a rule, was over the former.
