Truth

We must not look for truth in the deeds and actions of nations; we must investigate truth at its divine source.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 85

When you meet those whose opinions differ from your own, do not turn away your face from them. All are seeking truth, and there are many roads leading thereto. Truth has many aspects, but it remains always and forever one. Do not allow difference of opinion, or diversity of thought to separate you from your fellow-men, or to be the cause of dispute, hatred and strife in your hearts. Rather, search diligently for the truth and make all men your friends.

‘Abdu’l-Bahá, Paris Talks, p. 53

All men, not scholars alone, are exhorted to seek out and uphold the truth, no matter how uncomfortable it may be. But they are also exhorted to be wise in their utterance, to be tolerant of the views of others, to be courteous in their behaviour and speech, not to sow the seeds of doubt in faithful hearts, to look at the good rather than at the bad, to avoid conflict and contention, to be reverent, to be faithful to the Covenant of God, to promote His Faith and safeguard its honour, and to educate their fellowmen, giving milk to babes and meat to those who are stronger.

It has been suggested that the words of Bahá’u’lláh that a true seeker should "so cleanse his heart that no remnant of either love or hate may linger therein, lest that love blindly incline him to error, or that hate repel him away from the truth," support the viewpoint of methodological agnosticism. But we believe that on deeper reflection it will be recognized that love and hate are emotional attachments or repulsions that can irrationally influence the seeker; they are not aspects of the truth itself.

Moreover, the whole passage concerns taking "the step of search in the path leading to the knowledge of the Ancient of Days" and is summarized by Bahá’u’lláh in the words: "Our purpose in revealing these convincing and weighty utterances is to impress upon the seeker that he should regard all else beside God as transient, and count all things save Him, Who is the Object of all adoration, as utter nothingness." It is in this context that He says, near the beginning of the passage, that the seeker must, "before all else, cleanse and purify his heart ... from the obscuring dust of all acquired knowledge, and the allusions of the embodiments of satanic fancy." It is similar, we think, to Bahá’u’lláh's injunction to look upon the Manifestation with His Own eyes. In scientific investigation when searching after the facts of any matter a Bahá’í must, of course, be entirely open-minded, but in his interpretation of the facts and his evaluation of evidence we do not see by what logic he can ignore the truth of the Bahá’í Revelation which he has already accepted; to do so would, we feel, be both hypocritical and unscholarly.

Scholarship has a high station in the Bahá’í teachings, and Bahá’í scholars have a great responsibility. We believe that they would do well to concentrate upon the ascertainment of truth -- of a fuller understanding of the subject of their scholarship, whatever its field -- not upon exposing and attacking the errors of others, whether they be of non-Bahá’í or of their fellow believers. Inevitably the demonstration of truth exposes the falsity of error, but the emphasis and motive are important. We refer to these words of Bahá’u’lláh: Consort with all men, O people of Bahá, in a spirit of friendliness and fellowship. If ye be aware of a certain truth, if ye possess a jewel, of which others are deprived, share it with them in a language of utmost kindliness and goodwill. If it be accepted, if it fulfil its purpose, your object is attained. If any one should refuse it, leave him unto himself, and beseech God to guide him. Beware lest ye deal unkindly with him. A kindly tongue is the lodestone of the hearts of men. It is the bread of the spirit, it clotheth the words with meaning, it is the fountain of the light of wisdom and understanding.
